This year will be the 76th anniversary of the MG.42, the only machine gun created during the Second World War that is still used in the armies of many countries.
Many military historians claim that the Maschinengewehr 42 (better known as the MG 42) was the best general purpose machine gun ever created by human genius.
I remembered him well as a kid from films about the Great Patriotic War. Let's remember the history and features of this weapon...
In 1937, three German companies took part in the competition to develop a new single machine gun: Rheinmetall-Borsig A.G., Stubgen A.G. and Metall und Lackierwarenfabrik Johannes Grossfuss AG. In April of the following year, competitive tests were carried out, from which the machine gun of Grossfuss engineer Werner Gruner emerged as the winner. After extensive refinement of the design, 1,500 machine guns, first designated MG.39 and subsequently MG.39/41, were sent to the Eastern Front at the end of 1941 for the last military tests, where they showed their best performance. And soon the modernized model was adopted by the Wehrmacht under the designation “7.92 mm single machine gun MG.42". The first combat use of the new machine gun was its use by General Rommel's infantrymen in the Battle of Ghazala (Tunisia) in May-June 1942.
The MG.42 machine gun was a typical representative of wartime weapons. With the exception of the barrel, bolt, muzzle, clamp and sear, all parts of the machine gun are stamped. MG.42 consisted of the following main parts, assemblies and mechanisms: barrel with breech; locking mechanism; return spring; machine gun box with muzzle device; barrel return mechanism; bipod; lid boxes with a feeding mechanism; tape feed mechanism; trigger mechanism; butt with butt plate and buffer; sighting devices.
The automatic machine gun operated on the principle of using the recoil of the barrel during its short stroke and removing part of the powder gases through the muzzle device to increase the recoil energy. In order to simplify the design, the rotation of the combat cylinder was replaced by its translational movement, while the barrel bore was locked by two symmetrical rollers, which were moved apart by the figured faces of the breech and the bolt stem. The locking mechanism is combined with a shutter acceleration mechanism. All the main mechanisms and accessories of the machine gun are mounted in a box.
Striker-type impact mechanism. The trigger mechanism was designed only for continuous fire. A push-button safety, assembled in the pistol grip of the fire control, locked the sear of the trigger mechanism. The sight is an open sector type, designed for a firing range of up to 2000 m. The front sight, mounted in the front part of the barrel casing on a bracket, could be adjusted in height and in the lateral direction. In the stowed position, the bracket with the front sight was pressed against the casing and secured with a tension rod and a spring. The length of the sighting line is small compared to other German machine guns (430 mm), and the sight slot (neck) was located at a large distance from the butt plate (550 mm). Such a large distance from the shooter’s eye to the sight slot had a positive side, because the slot was within the depth of field of the eye and did not blur when aiming. However, the small size of the slot itself worsened the visibility of the target, especially at dusk.
The sight clamp moved along the bar with clicks, which was achieved by the presence of a spring tension in the clamp and cutouts on the bar itself. This design of the sight made it possible to install it by ear and touch in conditions of poor visibility: when shooting from embrasures, from attics, etc. For shooting at air targets, the MG.42 could also use a sight for anti-aircraft shooting. The barrel was cooled by air, and the machine gun had large oval windows in the barrel casing for more intense heat transfer, and on the right side there was a full-length cutout for changing the barrel. The barrel had relatively small weight and size characteristics, which was done to increase the maneuverability of the weapon at the expense of the ability to conduct long-term continuous fire.
One of the distinctive features of the MG.42 was the quick-change barrel mechanism. The overheated barrel was simply snapped off from the body (a special clamp was provided for this), and a new one was placed in its place. The entire operation took no more than a couple of seconds and could be performed with one hand.
A slider-type direct cartridge feeding mechanism assembled in the box lid with a double feed finger system ensured smooth feeding of the tape when the bolt moved back and forth, as well as the absence of delays, despite the high rate of fire (1200-1300 rds/min). The cartridges were fed from a metal one-piece hinged link tape with an open link. One piece of 50-round belt could be connected to another using a cartridge, so the length of the loaded belt could be increased as much as desired.
The high rate of fire, which was achieved thanks to the rectilinear sliding movement of the bolt parts and the use of an improved buffer, is explained by the desire of the Wehrmacht command not only to increase the density of fire of infantry units, but also to increase the effectiveness of fire on moving and briefly appearing targets. When designing moving parts of automation, large tolerances between non-working surfaces and small values of rubbing surfaces were deliberately established, which made the operation of the weapon less sensitive to grease, contamination and unfavorable climatic conditions. The new MG.42 machine gun did not require careful maintenance and, which was extremely important for use in front-line conditions, it could be fired without any lubrication. The machine gun could be easily operated by one person, since the weight of the weapon in the light machine gun version was 11.4 kg. The bipod in the MG.42 could be attached, depending on the nature of the terrain, to the front or rear of the barrel casing. On a bipod, the machine gun was able to conduct aimed fire at a range of up to 800 m.
The indisputable advantages of the MG.42 included its simplicity and ease of maintenance, the speed of preparing the weapon for battle, the ease of its assembly and disassembly, and the relatively smooth operation of the automation, with the exception of the shock of the bolt in the forward position. But at the same time, the machine gun also had certain disadvantages: bulkiness (total length 1220 mm); the rate of fire was excessively high for a light machine gun, which led to rapid heating of the barrel and frequent cases of non-extraction of the cartridge case; low accuracy of combat (at a distance of 100 m the dispersion was approximately 25 cm), therefore, to ensure high accuracy, it was recommended to fire a machine gun in short bursts of 5-7 shots; the small distance from the butt to the reloading handle in its rear position (200 mm) required the butt to be lifted from the shoulder to cock the bolt, which to a certain extent reduced the combat capabilities of this otherwise successful model.
In the easel version, the MG.42 machine gun was mounted on a universal tripod machine model 42. Standard optical sights MGZ.34 and MGZ.40 were mounted on the machine, allowing shooting at a distance of up to 2,200 m.
During the war, the Germans tried to improve the machine gun. In 1943, experimental work was carried out to equip the MG.42 with a device for silent and flameless shooting weighing 3.5 kg, 350 mm long and 110 mm in diameter. Precision shooting was carried out at a distance of up to 150 m. The following year, an experimental version of this machine gun with a barrel curved by 30 degrees appeared.
The simplicity of the MG.42 design made it possible to train full-fledged riflemen in the shortest possible time (in total, before the end of the war, the Germans managed to train 400,000 machine gunners). According to the 1944 states, the infantry regiment was supposed to have 118 light and 24 heavy machine guns MG.42. In total, 408,323 MG.42 machine guns were manufactured before the end of the war.
A huge number of MG-42 machine guns were captured by the Red Army and used in battle for their intended purpose. The soldiers preferred to keep quiet about the fact that during the battle they captured a machine gun and kept it in their units for as long as possible.
After 1945, a significant number of MG-42s were distributed throughout Europe. Many European armies adopted it. The French fought with him in Indochina. But only one country captured so many machine guns that it was able to almost completely arm its army with them. This was Yugoslavia. The Yugoslavs liked the MG-42 so much that they even began assembling it in their homeland. They kept the caliber 7.92 mm and even produced a machine gun for export. The Yugoslav variant is known as the M-53 and is an exact copy German machine gun, as well as all its accessories, including the machine.
When the West German army needed a new machine gun, the MG-42 was chosen for modernization. And to this day its modernized version, converted to the NATO cartridge, MG-3, is in service.
After the end of World War II, this weapon, despite the crushing defeat of the Third Reich, found a rebirth due to its uniqueness. Thus, American experts still consider the MG.42 machine gun “one of the most remarkable examples of automatic weapons ever produced anywhere,” and that “its design influenced the development of new industrial production methods and will continue to do so for a long time.” influence the production of automatic weapons in the coming years.”
After Germany joined the North Atlantic bloc in 1959, the Bundeswehr adopted a single machine gun MG.42/59, which was an almost exact copy of the MG.42, but re-barreled for the new 7.62x51 NATO rifle and machine gun cartridge. In order to bring the characteristics of this far from old machine gun up to the level of modern requirements, Germany has been working for a number of years to improve its design, related to increasing the operational and combat qualities of the MG.42. As a result, several variants of the MG.42/59 machine gun appeared: MG.1 (used as a manual one - on a bipod, easel - on a tripod machine, anti-aircraft and tank), MG.1A3 (used as a manual one - on a bipod, easel - on a machine -tripod and anti-aircraft), MG.1A4 (used only in the tank version). 25 improvements were made to their design.
Horizontal adjustment of the rear sight, constant height of the front sight, hardening of the sight base, chrome plating of the barrel guide bushing made of heat-resistant material, finer adjustment of the recoil force of the barrel have been introduced (on the muzzle, instead of 8 fixing grooves, 36 are made), the design of the muzzle itself has been simplified (now consists of 2 parts ), the trigger force has been reduced (7-8 kg instead of 11-13 kg), etc. In addition, the survivability of the barrel was increased threefold as a result of the use of improved heat-resistant steel grades, hard chrome plating and uniform (conical) narrowing of the barrel bore to the muzzle. The survivability of moving automation parts has increased due to the use of high-quality materials. The feed roller on the shutter is spring-loaded, which makes it possible to close the box lid at any position of the shutter. The hinged head of the bipod has been strengthened. Tolerances on the dimensions of parts have in most cases been expanded.
Subsequently, 36 more changes were made to the design of the single Bundeswehr machine gun MG.1A3, aimed at increasing its efficiency and increasing the reliability of the automation. As a result of these works, in 1968, the West German armed forces adopted an improved model of a single machine gun called MG.3. In order to unify standard components and parts of small arms of the North Atlantic Alliance, the feed mechanism in the machine gun has been completely redesigned and the possibility of using all three cartridge belts used in the armies of NATO countries has been ensured: the German non-loose metal DM.1, as well as the loose link ones - the German DM.13 and the American (from the M60 machine gun) US M13. A disc brake has been introduced for the box cover, holding it in the open position in the range from 0 to 95 degrees. To more completely remove powder deposits, the pressure cavity in the muzzle is given a conical shape. The return spring force has been increased by 30%. A guide bushing is butt welded to the receiver. Each machine gun is equipped with a folding anti-aircraft sight. In MG.3, sighting devices are designed for a firing range of up to 1200 m.
Another innovation was the use of a barrel with a polygonal (multi-arc) channel profile, developed jointly by Rheinmetall GmbH and Heckler and Koch. Such a bore did not have the usual rifling and fields with sharp edges. Its profile is formed by 8 arcs of tangent radii, four of which are fields and four are rifling. The nominal caliber of the barrel is reduced so that the cross-section of the bullet becomes larger than the cross-section of the bore. The polygonal (multi-arc) profile of the barrel bore, combined with its reduced cross-section, ensures that there is no breakthrough of powder gases between the bullet and the inner surface of the barrel bore when firing, which ensures almost the same barrel survivability as that of expensive MG.1A3 machine gun barrels with a conical bore and a solid chrome plating
One of the features of the MG.3 was the ability to change the rate of fire in the range from 700-800 to 1300 rounds/min. A reduction in the rate of fire is achieved both through the use of a new spring-loaded plunger located in the bolt (in this case, the plunger resists the displacement of the locking rollers of the bolt inward when unlocked, thereby reducing the rate of fire), and the use of bolts with different masses and buffer springs of different stiffness. In export versions, the MG.3 barrel may have a liner made of a special alloy - stellite. The machine gun can also be used as an on-board weapon for tanks, armored personnel carriers, infantry fighting vehicles and helicopters. In this version, the machine gun received the index MG.3A1.
And today, 76 years after its creation, such an effective and high-quality weapon as the single MG.42 machine gun and its numerous modifications continues its military service. And not only in the Bundeswehr and special forces of both the West German armed forces and law enforcement(GSG-9), but also in the armies of other states, including Austria, Burma, Denmark, Indonesia, Norway, the United Arab Emirates, Sudan, Chile. In addition, under license from Rheinmetall GmbH, the MG.3 single machine gun is produced in Italy, Iran, Spain, Pakistan, Turkey and Yugoslavia.

War may never change, but its tools have changed many times. Ever since humanity moved from spears and arrows to firearms, it never ceases to improve it every year. In this review, we invite you to consider the best representatives of the “weapons family”. We will talk about both large-caliber and light machine guns - new items and classic models, competing in rate of fire, power and lethality.
A single German HK 121 machine gun replaced the famous MG 3. No matter how good the “troika” was, everything ends sooner or later. The Bundeswehr needed a more powerful option to support its army, which was the creation of the weapons company Heckler & Koch. Smart layout, lethal power, quick-change barrel, possibility of installation on military equipment– what else is needed to make a machine gunner happy?

The Negev machine gun, produced by the Israeli concern Israel Military Industries, has proven itself to be a powerful and mobile support weapon. But its firing range and lethality were clearly not enough for modern military conflicts. That is why the updated Negev NG7 entered service with the Israeli army, which corrected all the shortcomings of its predecessor.

FN MAG can rightfully be called the “Belgian horse” in the class small arms. The gunsmiths from Fabrique Nationale did their best, creating a truly good machine gun. A fairly simple and reliable design, combined with flexibility of use and adequate ammunition, has secured this machine gun a place in the weapons systems of over 50 countries, including Belgium itself, the UK, Australia, Canada, the USA, Sweden and many other countries.

Most domestic and foreign experts agree that the large-caliber machine gun "KORD" (Large-caliber Gun of Dyagterevtsev) is the best of its kind.
In the armed forces, the KORD is called a “sniper machine gun” for its amazing accuracy and mobility, which is unusual for this type of weapon. With a caliber of 12.7 mm, its weight is only 25.5 kilograms (body). Also, “KORD” is highly valued for its ability to fire both from a bipod and from the hands at a speed of up to 750 rounds per minute.

For several decades after the end of World War II, designers of light armored vehicles in Western countries developed their combat vehicles in such a way that their armor could withstand the armor-piercing bullets of the Soviet heavy machine gun of the S.V. system. Vladimirova KPV (GAU index 56-P-562).
This is explained by the fact that the KPV machine gun, which was in service with the Soviet army, was developed in 1944 as a weapon in which the rate of fire and accuracy of a heavy machine gun are optimally combined with the armor-piercing ability of an anti-tank rifle.
The ammunition adopted for the machine gun - a 14.5 x 114 mm cartridge - was developed for anti-tank rifles in the late 1930s, its first samples with an armor-piercing incendiary bullet with a steel (metal-ceramic) BS-41 and a B-32 core were adopted for service Red Army on July 16 and August 15, 1941, respectively.
When firing from a KPV, the muzzle energy of an armor-piercing 14.5 mm bullet exceeds the energy of bullets from 12.7 mm machine guns by almost two times; at a distance of 500 m, these bullets hit a vertically located armor plate up to 32 mm thick, so it is not for nothing that the KPV machine gun is considered powerful a means of combating not only armored personnel carriers and combat reconnaissance vehicles, but also infantry fighting vehicles and light tanks. The combat use capabilities of the KPV have been expanded due to the inclusion in its ammunition of 14.5 mm cartridges with armor-piercing incendiary tracer bullets BZ T and BST, incendiary bullets ZP and instantaneous incendiary bullets MDZ.
Kovrov enterprise OJSC Plant named after V.A. Degtyareva» in 1998, mastered the production of the 12.7-mm KORD machine gun (Kovron Gunsmiths Deggyarevtsy). The basic version of the machine gun is the tank version. It was assigned the GRAU index 6 P49. The infantry version has the GRAU index 6 P50. The need to develop and launch production of this machine gun is due to the fact that after the collapse of the USSR, supplies of the standard 12.7-mm machine gun of the Russian Army NSV-12.7 from the Kazakh manufacturing plant "Metalist" were in question.
KORD is designed to combat lightly armored targets and enemy fire weapons and to destroy enemy personnel at ranges of up to 1500 - 2000 m.
The machine gun also ensures destruction of air targets at slant ranges up to 1500 m.
KORD ensures effective shooting from both prepared and unprepared firing positions, as well as from buildings, stationary or moving vehicles in any position of the shooter. At the same time, the relatively light weight of the complex and the ability to quickly transfer the machine gun from the traveling position to the combat position allow the crew to easily change firing positions. And this, in turn, increases survivability, surprise and effectiveness of impact on the target.
It is noteworthy that in terms of overall dimensions, weight and docking characteristics, the KORD is similar to the NSV-12.7 machine gun, which ensures the replacement of the latter in all machine gun weapon systems without additional technical work.
During the Great Patriotic War, units of the Red Army successfully used a heavy machine gun DShK to combat enemy aircraft. The use of this machine gun as an infantry one was difficult due to its large weight - 155 kg.
At the end of the war, the DShK was retained in the small arms system of the Soviet infantry, but already in 1969, a group of designers consisting of G. I. Nikitin, V. I. Volkov and Yu. M. Sokolov was tasked with developing a new 12.7 mm machine gun , meeting modern tactical and technical requirements.
Work on the design, production of prototypes and their testing was completed in a relatively short time, and in 1972 the machine gun was adopted by the Soviet army under the designation “12.7-mm heavy machine gun NSV-12.7 (“Utes”).”
The abbreviation NSV was assigned to the machine gun based on the first letters of the designers' surnames - Nikitin, Sokolov, Volkov. The machine gun is assigned the index GRAU 6P11.
The infantry version of the machine gun on the alarm machine 6 T7 designed by K. A. Baryshev and A. V. Stepanov has the designation “NSVS-12.7”, index GRAU 6 P16. The NSVT-12.7 version (GRAU index 6 P17) has been developed for placement on anti-aircraft tank installations.
The airborne troops received a machine gun in the form of an anti-aircraft installation on the 6U6 machine, and for arming long-term fire installations, a version of the machine gun was produced on the 6U10 and 6U11 machines.
The Utes-M-12.7 shipborne turret-mounted machine gun mount should also be mentioned.
The machine gun has established itself as a powerful automatic weapon, providing reliable
On October 27, 1925, the Revolutionary Military Council of the USSR, the body of the highest military power of the USSR, by its resolution ordered the Artillery Committee of the Main artillery control by May 1, 1927, develop a machine gun with a caliber of 12 to 20 mm. Unlike similar machine guns that were being developed abroad at that time as primarily anti-tank weapons, the Soviet machine gun was intended to combat enemy air forces, while the solution of other tasks associated with its use should not be to the detriment of this goal.
The relatively short period of time allotted by the Revolutionary Military Council for the development of the machine gun was due to the fact that they planned to borrow the English 12.7 x 80 mm Vickers.50 cartridge as ammunition, and the machine gun itself was to be designed according to the design of the German Dreyse light machine gun.
The design of the first Soviet heavy machine gun was entrusted to the designers of the Tula Arms Plant. The prototype of the P-5 machine gun (5-line machine gun) they presented received a negative assessment during testing, since the reliability of its automation turned out to be unsatisfactory and the rate of fire was not high enough. In addition, it turned out that the power of the English cartridge did not reliably defeat the armor of tanks of that time.
Based on the test results, the Cartridge Tube Trust was instructed to develop a 12.7 mm cartridge increased power, The Tula Arms Plant was asked to modify the machine gun, and the Kovrov Union Plant No. 2 was involved in the work on creating a machine gun.
The cartridge designed by the Cartridge-Tube Trust was put into service
The single machine gun of the Kalashnikov system (PK, PKB, PKS, PKT) in service with the Russian Army is a powerful automatic weapon that ensures reliable destruction of enemy personnel and firepower at a range of up to 1000 m. Conducted in the late 1960s. The modernization of this machine gun was aimed primarily at changing the production technology of individual parts, which helped reduce the cost and labor intensity of its production. At the same time experience combat use machine gun showed that warming up the barrel during prolonged firing significantly reduces the effectiveness of shooting, and thermal leads of the barrel make it difficult or even impossible to use optical and night sights. In addition, the formation of a stream of heated air on the surface of the barrel causes the effect of a “mirage” or “floating target” and leads to errors in aiming. At the same time, the spare barrel included in the machine gun kit, intended to replace a heated barrel, increases its weight and complicates transportation, maintenance and storage.
To eliminate this drawback, which is characteristic of many modern single machine guns, the designers of the TsNIITOCHMASH enterprise have developed a new single machine gun "Pecheneg". In the version of the light machine gun it has the index GRAU b P41, in the version of the heavy machine gun on the machine b T5 designed by L. V. Stepanovn - 6 P41 S. Manual and heavy machine guns, equipped with a strap for attaching a night sight, are assigned the indices b P41 N and 6 P41 CH, respectively.
The new machine gun was developed on the basis of the modernized single Kalashnikov machine gun
In the battles of World War II, the German infantry successfully used the so-called single machine guns MS-34 and MS-42. On bipods they were used as light machine guns, and on alarm machines - as easel ones. These same machine guns were installed on armored personnel carriers, tanks and even airplanes.
Work to create such machine gun were conducted in the USSR in the 1930s, they were resumed after the end of World War II. In 1947 - 1960 More than 20 models of single machine guns were tested. By the end of the 1950s. a single machine gun was considered the most successful
PN designed by G.I. Nikitin. A series of PN machine guns was ordered for military testing, and work was underway to create a tank version of the machine gun in addition to the already developed light and heavy machine guns.
The disadvantages of the PN included the low service life of parts and the so-called hydrophobia - if water or condensate entered the valve of the gas outlet device, the reliability of the automation system left much to be desired.
In the second half of 1958, the Izhevsk Machine-Building Plant was involved in the work on creating a single machine gun. The prototype of the single PK machine gun of the M.T. Kalashnikov system, presented by the plant at the end of 1958, initially did not cause delight among the company’s experts
At the beginning of the Great Patriotic War, production of Maxim heavy machine guns was launched in Tula, Izhevsk and Zlatoust. In 1942, 55,258 machine guns of this system were produced, but in order to fully satisfy the demands of the front, the mobilization of additional production capacity was required. Since there were practically no enterprises not involved in the production of military products, it was possible to get out of this situation only by developing a new lightweight heavy machine gun simple design, which operating enterprises could master it in the shortest possible time. Need
in the new lightweight heavy machine gun was also due to the fact that Maxim had a machine gun large mass and, as a result, machine-gun units had low mobility on the battlefield and could not effectively support the advancing infantry with fire.
I.V. Stalin, who knew Degtyarev well and believed in his talent, believed that a new heavy machine gun should be developed on the basis of the DS-39. The People's Commissariat of Armaments was also guided by this system, but in the summer of 1942, the designer of the Kovrov plant P. M. Goryunov presented everyone with a surprise - a model of the heavy machine gun he had invented.
To the credit of the People's Commissar of Armaments D.F. Ustinov, he was not afraid to support Goryunov’s work and, contrary to Stalin’s instructions, ordered the production and testing of his machine gun.
Tests of the Goryunov machine gun carried out in the spring of 1943 showed its undeniable superiority over the improved Degtyarev machine gun. This did not correspond to Stalin’s opinion, but he did not make the usual “personnel decisions” in such cases. As Deputy People's Commissar of Armaments V.N. Novikov recalled in his memoirs, having familiarized himself with the test report, Stalin “convened a meeting of the heads of the People’s Commissariats
The main automatic weapon of the Soviet infantry - the Maxim system heavy machine gun, with all its positive qualities, also had a significant drawback - its mass was too large. When conducting offensive operations, this circumstance made it difficult to use the machine gun itself and significantly reduced the tactical maneuverability of rifle units. During exercises, things sometimes got to the point that out of the 18 Maxim machine guns in the rifle battalion, only 6 were left in service, while the rest were sent to the convoy and the machine gunners were used as shooters.
Numerous attempts to modernize Maxim's machine gun was reduced to improve its performance characteristics and improve production technology. The problem of the large mass of the machine gun remained unresolved. For this reason, on June 13, 1928, the Red Army Headquarters decided to begin creating a new, lighter heavy machine gun. The Artillery Committee developed the tactical and technical requirements for this machine gun on August 2 of the same year. These requirements predetermined the main design features of the new model, namely: in order to unify the system, convenience and ease of training, the heavy machine gun should be designed like a DP light machine gun, have an air-cooled barrel, belt feeding, a rate of fire of 500 rounds/min and a combat rate of fire of 200 - 250 rounds/min, system weight with the machine no more than 30 kg, alarm or wheeled machine weighing no more than 15 kg.
The first version of a heavy machine gun, made taking into account these tactical and technical Maxim machine guns (GAU index 56-P-421). The main changes in its design were due to the adoption of a new 7.62 mm rifle cartridge with a heavy bullet mod. 1930 (7.62 D gl with a brass sleeve and 7.62 D gzh with a bimetallic sleeve, GAU indices 57-D-422 and 57-D-423, respectively). With less than that of a pointed (light) bullet arr. 1908, initial speed (800 m/s compared to 865 m/s for a pointed bullet), the bullet of this cartridge provides the greatest firing range - 3900 m, and the maximum firing range is 5000 m.
For this reason, the modernized machine gun of the Maxim system mod. 1910/1930 equipped with a modified rack sight with two aiming bars: one with divisions in hundreds of meters from 0 to 22 for a light bullet, and the second with divisions from 0 to 26 for a heavy one. A movable rear sight with the ability to make lateral corrections can move left and right along a special horizontal tube.
To increase the accuracy of long-range shooting, as well as to ensure the possibility of firing semi-direct and indirect fire, an optical sight and a quadrant protractor were installed on the machine gun. Periscope optical sight
A machine gun is a group or individual small arms automatic support weapon designed to hit various ground, surface and air targets with bullets. Automatic action, as a rule, is achieved by using the energy of exhaust powder gases, sometimes by using the recoil energy of the barrel.
The Gatling gun (English: Gatling gun - Gatling gun, also Gatling canister, sometimes simply “Gatling”) is a multi-barreled rapid-fire small arms weapon, one of the first examples of a machine gun.
Patented by Dr. Richard Jordan Gatling in 1862 under the name Revolving Battery Gun. The predecessor of the Gatling gun is the mitrailleuse.
The Gatling is equipped with a top-mounted magazine with gravity-fed ammunition (without a spring). During the cycle of rotating the block of barrels by 360°, each barrel fires a single shot, is released from the cartridge case and loaded again. During this time, natural cooling of the barrel occurs. The rotation of the barrels in the first Gatling models was carried out manually, in later ones an electric drive was used for it. The rate of fire of manually driven models ranged from 200 to 1000 rounds per minute, and when using an electric drive it could reach 3000 rounds per minute.
The first prototypes of the Gatling gun were first used during the American Civil War. Machine guns were adopted by the US Army in 1866 after a manufacturing company representative demonstrated them on the battlefield. With the advent of single-barrel machine guns, operating on the principle of using the recoil energy of the barrel during its short stroke, the Gatling gun, like other multi-barrel systems, gradually fell out of use. Their significantly higher rate of fire did not have a significant impact on the fate of the Gatlings, since at that time there was no longer any special need for a rate of fire above 400 rounds per minute. But single-barrel systems clearly outperformed the Gatling gun in weight, maneuverability and ease of loading, which ultimately determined the priority of the single-barrel system. But the Gatlings were never completely supplanted - they continued to be installed on warships as air defense systems. Multi-barreled systems gained particular relevance during the Second World War, when the progress of aviation required the creation of automatic cannons and machine guns with a very high rate of fire.
The first truly operational machine gun, using the energy of the previous shot to reload, appeared in the United States only in 1895, through the works of the legendary gunsmith John Moses Browning. Browning began experimenting with weapons that used the energy of powder gases for reloading back in 1891. The first experimental model, created by him for the .45-70 cartridge with black powder, was demonstrated to Colt, and businessmen from Hartford agreed to finance further work in this direction. In 1896, the US Navy adopted the Colt M1895 machine gun, developed by Browning, in a version chambered for the 6mm Lee cartridge, which was in service with the fleet at that time. During the same period, the US Army purchased a small number of M1895 machine guns (nicknamed “potato diggers” by the troops for the characteristic lever swinging under the barrel) in a version chambered for the 30-40 Krag army cartridge. M1895 machine guns received baptism of fire(side by side with hand-cranked Gatling guns) in the US-Spain conflict that took place in Cuba in 1898. It is interesting that later Russia became one of the most widespread users of Browning M1895 machine guns, purchasing them in significant quantities (chambered in Russian 7.62mm) after the outbreak of the First World War.
The Colt Model 1895 machine gun used gas-operated automatics with a piston located under the barrel that rocked back and forth in a vertical plane. In the position before the shot, the gas piston lever was located under the barrel parallel to it, the piston head entered the transverse gas outlet hole in the barrel wall. After the shot, the powder gases pushed the piston head down, causing the piston lever to rotate down and back around an axis located under the barrel closer to the receiver of the weapon. Through a system of pushers, the movement of the lever was transmitted to the bolt, and a distinctive feature of the system was that in the initial period of opening the bolt, its rollback speed was minimal, and the opening force was maximum, which significantly increased the reliability of removing spent cartridges. The barrel bore was locked by skewing the rear part of the bolt downwards. The massive lever, swinging under the barrel at a considerable speed, required sufficient free space under the barrel of the machine gun, otherwise the lever began to literally dig up the ground, for which the machine gun received the nickname “potato digger” among the troops.
The machine gun barrel was air-cooled, non-replaceable, and had a fairly significant mass. The machine gun fired from a closed bolt, with automatic fire only. The trigger mechanism included a trigger hidden inside the receiver. The cocking handle was located on the swinging lever of the gas piston. To simplify loading, a cord was sometimes attached to it, with a jerk for recharging. The cartridges were fed from canvas belts; the cartridge was fed from the tape in two steps - as the bolt rolled back, the cartridge was pulled back from the belt, and then fed into the chamber as the bolt rolled back. The tape feeding mechanism had a simple design and used a gear shaft driven through a ratchet mechanism by a bolt pusher connected to a gas piston. The direction of feed of the tape is from left to right. The fire controls included a single pistol grip on the buttplate of the receiver, which later became traditional for Browning machine guns, and a trigger. The machine gun was used from a massive tripod machine of a relatively simple design, which had guidance mechanisms and a saddle for the shooter.
In 1905, tests began in Austria to determine a new, promising machine gun system for the armed forces of the empire. In these tests, the already well-tried and tested system of Sir Hiram Maxim and the new, just patented design of the German Andreas Wilhelm Schwarzlose came face to face. Currently fairly forgotten, the Schwarzlose machine gun was quite a serious weapon for its time. It was reliable, provided firepower quite comparable to the Maxims (except that the effective firing range was shorter), and most importantly, it was noticeably simpler and cheaper to manufacture than the Maxim machine gun or the modified Skoda machine gun. In 1907, after two years of testing and improvements, the Schwarzlose machine gun was adopted by the Austrian Army. Production of the new model was established at an arms factory in the city of Steyr. In 1912, the machine gun underwent a minor modernization, receiving the designation M1907/12. The main differences of this version were the improved design of the lever pair of the shutter and the reinforced design of a number of parts. The external difference was the different shape of the receiver cover, in the front part now reaching the rear section of the barrel casing.
It must be said that the machine gun turned out to be successful - following Austria-Hungary, it was adopted into service in Holland and Sweden (both countries established licensed production of Schwarzlose machine guns, which continued until the mid-1930s). In addition, even before the First World War, Bulgaria, Greece, Romania, Serbia and Turkey purchased Schwarzlose guns in the calibers accepted in their armies. After the loss in the First World War and the subsequent collapse of the empire, these machine guns remained in service in new countries - former parts of the empire (Austria, Hungary and Czechoslovakia). During the war, a fair number of Schwarzlose machine guns were captured by the enemies of the empire - Russia and Italy, while in the Russian army the Schwarzlose machine gun was studied in machine gunner courses along with Maxim and Browning machine guns. In Italy, the captured machine guns were kept in storage until the next war, during which they were used by the Italian army in the African theater of operations (in the original caliber 8x50R).
The machine gun's barrel is relatively short and, as a rule, is equipped with a long conical shock absorber, which reduces the shooter's blinding from the muzzle flash when shooting at dusk.
The cartridges are fed by a belt feed; the canvas feed is fed only from the right side. The cartridge supply system has an extremely simple design with a minimum of parts. The basis of the tape feed mechanism is a toothed drum, each slot of which accommodates one cartridge in the tape pocket. The rotation of the drum is carried out by a simple ratcheting mechanism when the bolt is rolled back, while the topmost cartridge in the drum is removed from the belt back by a special protrusion on the bottom of the bolt when it is rolled back and then fed forward into the chamber as the bolt rolls back. Spent cartridges are thrown out through a window in the left wall of the receiver.
The Maxim machine gun is a heavy machine gun developed by American-born British gunsmith Hiram Stevens Maxim in 1883. The Maxim machine gun became one of the founders of automatic weapons; it was widely used during the Boer War of 1899-1902, World War I and World War II, and in many minor wars and armed conflicts of the 20th century, and is also found in hot spots around the world and in our days.
In 1873, the American inventor Hiram Stephens Maxim (1840-1916) created the first example of an automatic weapon - the Maxim machine gun. He decided to use the recoil energy of the weapon, which had not been used in any way before. But testing and practical use of these weapons were stopped for 10 years, since Maxim was not only a gunsmith and was interested in other things in addition to weapons. His range of interests included various technology, electricity, and so on, and the machine gun was just one of his many inventions. In the early 1880s, Maxim finally took up his machine gun, but in appearance his weapon was already very different from the 1873 model. Perhaps these ten years were spent thinking about, calculating and improving the design in the drawings. After this, Hiram Maxim made a proposal to the US government to accept his machine gun for service. But no one in the USA was interested in the invention, and then Maxim emigrated to Great Britain, where its development initially also did not arouse much interest from the military. However, the British banker Nathaniel Rothschild, who was present at the testing of the new weapon, became seriously interested in it and agreed to finance the development and production of the machine gun.
After a successful demonstration of the machine gun in Switzerland, Italy and Austria, Hiram Maxim came to Russia with a demonstrative example of a .45 caliber (11.43 mm) machine gun.
In 1887, the Maxim machine gun chambered for the 10.67 mm Berdan rifle cartridge with black powder was tested.
On March 8, 1888, Emperor Alexander III fired from it. After the tests, representatives of the Russian military department ordered Maxim 12 machine guns mod. 1895 chambered for the 10.67 mm Berdan rifle cartridge.
The company “Sons of Vickers and Maxim” began supplying Maxim machine guns to Russia. The machine guns were delivered to St. Petersburg in May 1899. The Russian navy also became interested in the new weapon and ordered two more machine guns for testing.
Subsequently, the Berdan rifle was removed from service, and the Maxim machine guns were converted to accept the 7.62 mm cartridge of the Russian Mosin rifle. In 1891-1892 Five machine guns chambered for 7.62x54 mm cartridges were purchased for testing. During 1897-1904 Another 291 machine guns were purchased.
By the end of the 1930s, the Maxim design was obsolete. The machine gun without the machine, water and cartridges had a mass of about 20 kg. The weight of Sokolov's machine is 40 kg, plus 5 kg of water. Since it was impossible to use a machine gun without a machine and water, the working weight of the entire system (without cartridges) was about 65 kg. Moving such weight across the battlefield under fire was not easy. The high profile made camouflage difficult; Damage to the thin-walled casing in battle by a bullet or shrapnel practically rendered the machine gun inoperable. It was difficult to use Maxim in the mountains, where fighters had to use homemade tripods instead of standard machines. Significant difficulties in summer time caused the machine gun to be supplied with water. In addition, the Maxim system was very difficult to maintain. The cloth tape caused a lot of trouble - it was difficult to equip, it wore out, broke, and absorbed water. For comparison, the single Wehrmacht machine gun MG-34 had a mass of 10.5 kg without cartridges, was powered by a metal belt and did not require water for cooling (while being somewhat inferior to the Maxim in firepower, being in this indicator closer to the Degtyarev light machine gun, although and with one important nuance - the MG34 had a quick-change barrel, which made it possible, if there were spare barrels, to fire more intensive bursts from it). Firing from the MG-34 could be carried out without a machine gun, which contributed to the secrecy of the machine gunner's position.
On the other hand, the positive properties of the Maxim were also noted: thanks to the shockless operation of the automatic system, it was very stable when fired from a standard machine gun, gave even better accuracy than later developments, and allowed very precise fire control. Provided proper maintenance, the machine gun could last twice as long as the established service life, which was already longer than that of new, lighter machine guns.

The 12.7mm (0.5 inch) machine gun was developed in the USA by John M. Browning at the end of the First World War. This machine gun was, in general, a slightly enlarged copy of the M1917 machine gun, designed by the same Browning, and had a water-cooled barrel. In 1923 it entered service with the US Army and Navy under the designation "M1921", primarily as an anti-aircraft weapon. In 1932, the machine gun underwent its first modernization, which consisted of the development of a universal design of mechanisms and receiver, which allowed the machine gun to be used both in aviation and in ground installations, with water or air cooling and the ability to change the direction of feed of the belt. This variant was designated M2, and began to enter service with the US Army and Navy in both air-cooled (as an infantry support weapon) and water-cooled (as an anti-aircraft weapon) version. To provide the necessary intensity of fire, a heavier barrel was developed in the air-cooled version, and the machine gun received its current designation Browning M2HB (Heavy Barrel). In addition to the USA, in the pre-war period, Browning heavy machine guns were also produced under license in Belgium, by the FN company. During the Second World War, almost 2 million M2 12.7mm machine guns were produced in the United States, of which about 400,000 were in the M2HB infantry version, used both on infantry machines and on various armored vehicles.
The Browning M2HB heavy-caliber machine gun uses the recoil energy of the barrel during its short stroke for automatic operation. The bolt is engaged with the barrel shank using a locking wedge that is movable in a vertical plane. The design includes a lever-type shutter accelerator. The barrel has its own return spring and recoil buffer; in the rear part of the receiver there is an additional recoil buffer for the bolt group. Air-cooled barrel, replaceable (quick-change without adjustments on modern versions). The cartridges are fed from a loose metal tape with a closed link; the direction of feed of the tape is switched by rearranging a special selector on the upper surface of the bolt and rearranging a number of parts of the tape feeding mechanism. The cartridge is removed from the belt by the bolt as it rolls back, then lowered to the chambering line and fed into the barrel as the bolt rolls back. The spent cartridges are thrown down.
In the United States, the problem of machine guns, which acutely arose with the country's entry into the First World War, was quickly and successfully solved by John Moses Browning in collaboration with the Colt company, in 1917 presenting his analogue of the Maxim machine gun, which, with similar characteristics, was distinguished by a greater simplicity of design. Already the very first prototype of a Browning machine gun with a water-cooled barrel set a kind of record, using 20 thousand rounds of ammunition in one test without a single breakdown. It is not surprising that by the end of the First World War, the production of these machine guns, designated M1917, went into tens of thousands. The very next year, on the basis of the M1917, Browning created the M1918 aviation machine gun with an air-cooled barrel, and a year later - the M1919 tank machine gun, also with air cooling. On the basis of the latter, Colt produces several models of “cavalry” machine guns on light machine guns, as well as export commercial samples for different calibers. In 1936, the M1917 machine gun, which at that time was the main machine gun for the US Army, underwent minor changes aimed at increasing its service life, but its main drawback - excessive weight (both the machine gun itself and the tripod machine) did not go away. Therefore, in 1940, a competition was announced for a new lightweight machine gun for the US Army. A significant part of the competitors were variations on the theme of Browning's design, but there were also purely original systems. However, none of the samples fully satisfied the requirements of the military, and as a result, a variant of the Browning M1919 machine gun in the M1919A4 version, complete with a lightweight M2 tripod machine, was adopted. It was the M1919A4 machine gun that became the main weapon of the American troops during the Second World War and the Korean War. However, a significant number of earlier M1917A1 machine guns also actively participated in combat operations in all theaters of war.
In 1941, the United States also announced a competition for a belt-fed light machine gun, in which several large corporations and government arsenals participated. It should be noted that the American military, like the Soviet military, also wanted too much from a light machine gun, and just like in the USSR, and as a result, the army had to be content with a palliative solution in the form of a modification of an existing machine gun. And since the US Army did not have a ready-made “normal” light machine gun, the Americans had to follow the path taken in other countries back in the First World War or immediately after it. This way was the creation of a lightweight “manual” version of the M1919A4 heavy machine gun, designated M1919A6. The result was a path and a reliable and relatively powerful, but very heavy and inconvenient weapon. In principle, special round boxes for a 100-round belt were developed for the M1919A6, attached to the machine gun, but in most cases the infantry used standard 200-round boxes with a belt, carried separately from the machine gun. Theoretically, this machine gun could be considered a single machine gun, since it made it possible to install it on a standard M2 machine gun (if the kit included a corresponding pin attached to the receiver), but in reality, the “big brother” M1919A4, which had more heavy barrel, etc. as a result, it provided greater capabilities for conducting intense fire. Interestingly, the Americans, apparently, were quite satisfied with the rate of fire of their machine guns, despite the fact that it was only a third of the rate of fire of the German MG 42 machine gun.
Variants of the Browning infantry machine guns were produced under license from Colt in Belgium at the FN plant and in Sweden at the Carl Gustaf plant, and without a license in Poland.
At the beginning of the 20th century, the French army was, one might say, at the forefront of military progress. In particular, it was the French who, back during the First World War, were the first to adopt self-loading rifles for mass production. They were the first to adopt and massively equip troops with a fundamentally new class of small arms - automatic rifles, which were used as squad-level support weapons (light machine guns in Russian terminology). It's about about a system that is often not very deservedly classified as one of the worst examples of its period, namely the CSRG M1915 automatic rifle, named after its creators - designers Chauchat, Sutter and Ribeyrolle, as well as the manufacturing company - Gladiator (Chauchat, Suterre, Ribeyrolle, Établissements des Cycles “Clément-Gladiator”).
This light machine gun was originally designed taking into account the possibility of its mass production at non-specialized enterprises (let me remind you that its main manufacturer during the war was the Gladiator bicycle factory). The machine gun became truly widespread - its production during 3 years of the war exceeded 250,000 units. It was mass production that also became the main weak point of the new model - the level of industry at that time did not allow for the required quality and stability of characteristics from sample to sample, which, combined with a rather complex design and a magazine open to dirt and dust, led to increased sensitivity of the weapon to contamination and general low reliability. However, with proper care and maintenance (and the crews of these machine guns were recruited from non-commissioned officers and trained for up to 3 months), the CSRG M1915 light machine gun provided acceptable combat effectiveness.
An additional stain on the reputation of the Shosha machine gun was put by the unsuccessful modification M1918, developed by order of the American Expeditionary Force in Europe under the American cartridge 30-06. During the process of reworking, the machine gun lost its capacity of already not very voluminous magazines (from 20 to 16 rounds), but most importantly, due to an error in the drawings of the “Americanized” Shoshas that came from nowhere, the barrels had an incorrect chamber configuration, which led to constant delays and problems with the extraction of spent cartridges.
In the post-war period, machine guns of the CSRG system were in service in Belgium, Greece, Denmark, Poland, France and a number of other countries (in variants for cartridges of the appropriate calibers adopted in these countries), until they were replaced by more successful models.
Lewis light machine gun (USA - UK)
American Isaac Lewis developed his light machine gun around 1910, based on an earlier machine gun design by Dr. Samuel McLean. The machine gun was proposed by the designer for weapons American army, but the response was a harsh refusal (caused by a long-standing personal conflict between the inventor and General Crozier, then head of the US Army Weapons Department). As a result, Lewis sent his steps to Europe, to Belgium, where in 1912 he founded the company Armes Automatiques Lewis SA to sell his brainchild. Since the company did not have its own production facilities, an order for the production of the first experimental batch of Lewis machine guns was placed with the English company Birmingham Small Arms (BSA) in 1913. Shortly before the outbreak of the First World War, Lewis machine guns were adopted by the Belgian army, and after the start of the war they began to enter service with the British army and royal air force. In addition, these machine guns were widely exported, including to Tsarist Russia. In the United States, the production of Lewis machine guns in caliber .30-06 in the interests of mainly the nascent air force and marine corps was launched by Savage Arms. In the twenties and thirties, Lewis machine guns were quite widely used in aviation in various countries, and the barrel casing and radiator were usually removed from them. During the Second World War, a significant number of British Lewis were withdrawn from reserves and used to arm territorial defense units and for air defense of small commercial transport ships.
The Lewis light machine gun uses gas-operated automatics with a long-stroke gas piston located under the barrel. The barrel is locked by turning the bolt onto four lugs located radially at the rear of the bolt. Shooting is carried out from an open bolt, with automatic fire only. Features of the machine gun include a spiral return spring acting on the gas piston rod through a gear and gear train, as well as an aluminum radiator on the barrel, enclosed in a thin-walled metal casing. The radiator casing protrudes forward in front of the muzzle, so that when firing, an air draft is formed through the casing along the radiator, from the breech of the barrel to the muzzle. The cartridges were fed from disk magazines attached to the top with a multi-layer (2 or 4 rows, capacity 47 and 97 rounds, respectively) cartridges arranged radially, with bullets to the axis of the disk. At the same time, the magazine did not have a feed spring - its rotation to feed the next cartridge to the chambering line was carried out using a special lever located on the machine gun and driven by the bolt. In the infantry version, the machine gun was equipped with a wooden butt and a removable bipod; sometimes a handle for carrying the weapon was placed on the barrel casing. Japanese Type 92 Lewis machine guns (produced under license) could additionally be used from special tripod machines.
Bren (Brno Enfield) - English light machine gun, modification of the Czechoslovak ZB-26 machine gun. Development of the Bren began in 1931. In 1934, the first version of the machine gun appeared, which was called ZGB-34. The final version appeared in 1938 and was put into production. The new machine gun got its name from the first two letters of the names of the cities of Brno and Enfield, where production was launched. The BREN Mk1 was adopted by the British troops on August 8, 1938.
The Bren was used by the British Army as an infantry squad light machine gun. The role of the heavy machine gun was assigned to water-cooled Vickers machine guns from the First World War. The Bren was originally designed for the .303 caliber cartridge, but was later chambered for the 7.62mm NATO cartridge. The machine guns showed good performance in various climatic conditions - from the harsh winters of Norway to the hot Persian Gulf region.
Light machine gun MG 13 ‘Dreyse’ (Germany)
In the late twenties and early thirties, the German company Rheinmetall developed a new light machine gun for the German army. This model was based on the design of the Dreyse MG 18 machine gun, created during the First World War in the same concern by designer Hugo Schmeisser. Taking this machine gun as a basis, the designers of Rheinmtetal, led by Louis Stange, redesigned it for magazine feeding and made a number of other changes. During development, this machine gun, according to German tradition, received the designation Gerat 13 (Device 13). In 1932, this “device” was adopted by the Wehrmacht, which was beginning to strengthen itself, under the designation MG 13, due to an attempt to deceive the Versailles Commission by passing off a new machine gun as an old design from 1913. The new light machine gun itself was quite in the spirit of its time, differing only in the presence of an S-shaped double drum magazine with increased capacity in addition to the traditional box-shaped one for that period of time.
The MG 13 light machine gun is an automatic weapon with an air-cooled quick-change barrel. The automatic machine gun uses the recoil of the barrel during its short stroke. The barrel is locked by a lever swinging in a vertical plane, located in the bolt box below and behind the bolt and in the forward position of the moving parts supporting the bolt at the rear. Shooting was carried out from a closed bolt, the trigger mechanism was trigger. The machine gun allowed automatic and single fire; the fire mode was selected by pressing the lower or upper segments of the trigger, respectively. The cartridges are fed from a 25-round box magazine attached to the left; spent cartridges are ejected to the right. For use as an anti-aircraft gun or on armored vehicles, the machine gun could be equipped with a twin drum magazine with a capacity of 75 rounds S-shape. The machine gun was standardly equipped with a folding bipod; for use in the anti-aircraft role, it was equipped with a lightweight folding tripod and an anti-aircraft ring sight. Distinctive features of the MG 13 were the ability to move the bipod to the front or rear of the barrel casing, as well as a side-folding metal stock in the standard configuration.
The MG-34 machine gun was developed German company Rheinmetall-Borsig, commissioned by the German army. The development of the machine gun was led by Louis Stange, however, when creating the machine gun, the developments of not only the Rheinmetall company and its subsidiaries, but also other companies, such as Mauser-Werke, for example. The machine gun was officially adopted by the Wehrmacht in 1934 and until 1942 it was officially the main machine gun not only of the infantry, but also tank troops Germany. In 1942, instead of the MG-34, the more advanced MG-42 machine gun was adopted, but production of the MG-34 did not stop until the end of World War II, as it continued to be used as a tank machine gun due to its greater adaptability to this compared to MG-42.
The MG-34 is primarily worthy of mention as the first single machine gun ever put into service. It embodied the concept of a universal machine gun, developed by the Wehrmacht from the experience of World War I, capable of performing the role of both a light light machine gun used from a bipod and an easel machine gun used from an infantry or anti-aircraft machine gun, as well as a tank gun used in twin and separate installations of tanks and combat cars Such unification simplified the supply and training of troops and ensured high tactical flexibility.
The MG-34 machine gun was equipped with a folding bipod, which could be mounted either in the muzzle of the casing, which ensured greater stability of the machine gun when firing, or in the rear of the casing, in front of the receiver, which provided a larger sector of fire. In the easel version, the MG-34 was placed on a tripod machine of a rather complex design. The machine had special mechanisms that provided automatic range dispersion when firing at distant targets, a recoil buffer, a separate fire control unit, and a mount for an optical sight. This machine provided firing only at ground targets, but could be equipped with a special adapter for firing at air targets. In addition, there was a special lightweight tripod machine for firing at air targets.
Overall, the MG-34 was very worthy weapon, however, its disadvantages primarily include increased sensitivity to contamination of mechanisms. In addition, it was too labor-intensive to produce and required too many resources, which was unacceptable for wartime conditions, which required the production of machine guns in huge quantities. That is why the much easier to manufacture and reliable MG-42 machine gun, which used more advanced technologies, was born. Nevertheless, the MG-34 was a very formidable and versatile weapon that has earned its honorable place in the history of small arms.
MG 42 (German: Maschinengewehr 42) - German single machine gun from the Second World War. Developed by Metall - und Lackwarenfabrik Johannes Großfuß in 1942. Among Soviet front-line soldiers and allies he received the nicknames “Bone Cutter” and “Hitler’s Circular”.
By the beginning of World War II, the Wehrmacht had the MG 34, created in the early 1930s, as its only machine gun. For all its advantages, it had two serious drawbacks: firstly, it turned out to be quite sensitive to contamination of the mechanisms; secondly, it was too labor-intensive and expensive to produce, which did not make it possible to satisfy the ever-increasing needs of the troops for machine guns.
The MG 42 was created by the little-known company Großfuß (Metall - und Lackwarenfabrik Johannes Großfuß AG). Design authors: Werner Gruner and Kurt Horn. Adopted by the Wehrmacht in 1942. The machine gun was put into production at the Grossfus company itself, as well as at the Mauser-Werke, Gustloff-Werke and other factories. Production of the MG 42 continued in Germany until the end of the war, with a total production of at least 400,000 machine guns. At the same time, the production of the MG 34, despite its shortcomings, was not completely curtailed, since, due to some design features (easy barrel change, the ability to feed tape from either side), it was more suitable for installation on tanks and combat vehicles.
The MG 42 was developed to meet very specific requirements: it had to be a single machine gun, as cheap as possible to manufacture, as reliable as possible and with high firepower (20-25 rounds per second), achieved by a relatively high rate of fire. Although the design of the MG 42 used some parts from the MG 34 machine gun (which eased the transition to production of a new model of machine gun in wartime conditions), overall it is an original system with high combat performance. Higher manufacturability of the machine gun was achieved through the widespread use of stamping and spot welding: the receiver, together with the barrel casing, was made by stamping from a single blank, whereas for the MG 34 these were two separate parts made on milling machines.
As in the MG 34 machine gun, the problem of barrel overheating during prolonged shooting was solved by replacing the barrel. The barrel was released by snapping a special clamp. Changing the barrel required a matter of seconds and one hand, and did not lead to delays in combat.
The Italians, who used an “ultra-light light machine gun” chambered for the Villar-Perosa M1915 pistol cartridge with varying success in the First World War, immediately after the end of the war began developing light machine guns, and here it should be noted that the most main feature“Machine gun business in Italian” was that for some reason non-weapons companies were developing and producing machine guns in Italy, in particular, the locomotive building company Breda (Societa Italiana Ernesto Breda). In 1924, the Breda company presented its first version of a light machine gun, which, along with the light machine gun of the automobile manufacturer FIAT, was purchased in quantities of several thousand pieces. Based on the experience of their comparative operation, the Italian army preferred the “locomotive” machine gun to the “automobile” one, and after a series of improvements in 1930 it adopted the Breda M1930 light machine gun of 6.5mm caliber, which became the main light machine gun of the Italian army in the Second World War. It must be said that this weapon certainly had a number of positive traits(for example, a really quick-change barrel and good reliability), but they were more than compensated for by a very specific fixed magazine and the need for an oiler built into the weapon to lubricate the cartridges. Apart from Italy, the only user of Breda M1930 machine guns was Portugal, which purchased them in a version chambered for the 7.92x57 Mauser cartridge.
The Breda M1930 light machine gun is an automatic weapon with an air-cooled quick-change barrel. The automatic machine gun uses the recoil of the barrel during its short stroke. The bolt is locked by a rotating sleeve placed on the breech of the barrel. On the inner surface of the sleeve there are grooves into which the radial lugs of the bolt fit. When fired, during the recoil process, the sleeve rotates using a protrusion that slides along the spiral groove of the receiver, releasing the bolt. Such a system does not provide reliable preliminary extraction of cartridges, therefore the design of the machine gun includes a small oiler in the receiver cover and a mechanism for lubricating cartridges before feeding them into the barrel. Shooting is carried out from a closed bolt, with automatic fire only. A special feature of the cartridge supply system is a fixed magazine mounted horizontally on the weapon on the right. To load, the magazine is tilted forward in a horizontal plane, after which 20 rounds are loaded into it using a special clip, the empty clip is removed and the magazine returns to the firing position. The machine gun has a folding bipod, a pistol grip for fire control and a wooden butt. If necessary, additional support could be installed under the butt.
The FN model D light machine gun was developed in 1932 by the famous Belgian company Fabrique Nationale (FN) as a development of the FN Model 1930 machine gun, which was, in turn, a modification of the American Colt R75 machine gun, created on the basis of the Browning BAR M1918 automatic rifle. The main differences between the Belgian machine gun and the American version were simplified disassembly (due to the introduction of a folding butt plate of the receiver), a modified trigger mechanism that provided two rates of automatic fire (fast and slow), and most importantly, the introduction of a quick-change air-cooled barrel (hence the model designation D - from Demontable”, i.e. removable barrel). The machine gun was in service with the Belgian army and was widely exported both before and after the Second World War. In 1957, by order of the Belgian Army, a number of FN model D machine guns were re-barreled with the 7.62x51 NATO cartridge, adapted for box magazines from the then new FN FAL rifle. Such machine guns were designated FN DA1 in the Belgian army. Production of FN model D machine guns continued until the early 1960s.
The FN model D light machine gun uses gas-operated automatics with a long-stroke gas piston located under the barrel. Shooting is carried out from an open bolt; the barrel is locked by tilting upward the combat cylinder located at the rear of the bolt. To ensure a reduced rate of fire, an inertial mechanism for slowing the rate of fire is installed in the butt of the machine gun. The machine gun used box magazines with a capacity of 20 rounds, attached to the weapon from below. The FN model D light machine gun was standardly equipped with a folding bipod, a pistol grip and a wooden butt. A carrying handle was attached to the barrel, which was also used to replace the hot barrel. The machine gun could also be used from a special infantry tripod.
The Madsen light machine gun is deservedly considered not only the first production model of this class of weapons in the world, but also one of the longest-lived. This machine gun was created at the end of the 19th - very beginning of the 20th century at the state arsenal in Copenhagen by its director Rasmussen and artillery captain Madsen, in the future - the Danish Minister of War. Soon after the adoption of the new machine gun, a group of private investors created the company Dansk Rekyl Riffel Syndikat A/S (DRRS), whose chief designer was a certain Jens Theodor Schouboe. The DRRS company, which later added Madsen's name to its name, established commercial production of new machine guns, while simultaneously taking whole line patents for its design were in the name of Shawbo, so for a long time it was he who was considered the author of the design of the Madsen machine gun.
Serial production of the machine gun was launched by the development company in 1905, mass serial production of Madsen machine guns continued until the early 1950s, and in the DISA / Madsen catalogs its variants were presented until the mid-1960s, while the machine gun was offered to customers in any of the existing rifle calibers from 6.5 to 8mm,” including the then new 7.62m NATO caliber. In the first half of the 20th century, buyers of Madsen machine guns included countries such as Great Britain, Holland, Denmark, China, the Russian Empire, Portugal, Finland, Mexico and many other countries in Asia and Latin America. At the end of the First World War, licensed production of Madsen machine guns was planned to be launched in Russia and England, but various reasons That did not happen. And despite the fact that in most countries these machine guns were removed from mass service in the 1970-80s, they can still be found in more remote corners of the planet, in no small part due to the high reliability and survivability of the design, as well as high-quality production. In addition to infantry versions, Madsen machine guns were widely used in aviation, from the advent of the first armed aircraft until the 1930s.
The Red Army entered the Great Patriotic War with fairly outdated Maxim machine guns mod. 1910, as well as a small number of Degtyarev DS-39 machine guns, which had a number of significant shortcomings. The need for newer and more advanced weapons was obvious, and therefore in the spring of 1942 the development of a new heavy machine gun chambered for a standard rifle cartridge began. A group of developers led by P.M. Goryunov, working at the Kovrov Machine Gun Plant, created a new model by the beginning of 1943, which entered military testing in March of the same year, and in May 1943 was put into service under the designation “7.62mm easel machine gun designed by Goryunov arr. 1943", or SG-43. At the end of the Great Patriotic War, the machine gun underwent modernization, and under the designation SGM it was produced until 1961 and was in service with the Soviet Army until the mid-1960s, when it began to be replaced by the newer single Kalashnikov machine gun in the easel version (PKS). In the version of the tank machine gun under the designation SGMT, this model was installed on almost all post-war Soviet tanks. In addition, there was an armored personnel carrier version of the SGMB.
SGM was also widely exported and managed to make its mark in South-East Asia(Korea, Vietnam), in addition, its copies and variations were produced in China and other countries.
The SG-43 machine gun is an automatic weapon with a gas automatic engine and belt feed. The gas engine has a long stroke piston, a gas regulator and is located under the barrel. The barrel is quick-change and has a special handle for easy replacement. On SG-43 machine guns the barrel is smooth on the outside, on SGM machine guns it has longitudinal valleys to facilitate and improve heat exchange. Locking the barrel is done by tilting the bolt to the side, behind the wall of the receiver. Food - from non-loose metal or canvas belts for 200 or 250 rounds, feeding the tape from left to right. Due to the fact that a cartridge with a flange and a tape with a closed link are used, the supply of cartridges is carried out in two stages. First, when the bolt moves backward, a special gripper connected to the bolt frame removes the cartridge from the belt back, after which the cartridge is lowered to the level of the bolt. Then, when the bolt moves forward, the cartridge is sent into the chamber. Shooting is carried out from an open bolt. On the SG-43 machine gun, the charging handle was located under the butt plate of the machine gun, between the twin fire control handles. On the SGM, the charging handle has been moved to the right side of the receiver.
The DP (Degtyarev, infantry) light machine gun was adopted by the Red Army in 1927 and became one of the first models created from scratch in the young Soviet state. The machine gun turned out to be quite successful and reliable, and was widely used as the main weapon of fire support for infantry of a platoon-company link until the end of the Great Patriotic War. At the end of the war, the DP machine gun and its modernized version DPM, created based on the experience of combat operations in 1943-44, were removed from the arsenal of the Soviet Army, and were widely supplied to countries and regimes “friendly” to the USSR, having been noted in the wars in Korea, Vietnam and others. Based on the experience gained in World War II, it became clear that the infantry needed single machine guns that combined increased firepower with high mobility. As an ersatz substitute for a single machine gun in a company link, on the basis of earlier developments in 1946, the RP-46 light machine gun was created and put into service, which was a modification of the DPM for belt feeding, which, coupled with a weighted barrel, provided greater firepower while maintaining acceptable maneuverability. However, the RP-46 never became a single machine gun, being used only with a bipod, and from the mid-1960s it was gradually replaced from the SA infantry weapon system by the new, more modern Kalashnikov single machine gun - the PK. Like previous models, the RP-46 was widely exported and was also produced abroad, including in China, under the designation Type 58.
The DP light machine gun is an automatic weapon with automation based on the removal of powder gases and magazine feed. The gas engine has a long stroke piston and gas regulator located under the barrel. The barrel itself is quick-change, partially hidden by a protective casing and equipped with a conical removable flash suppressor. The barrel is locked by two lugs, moved to the sides when the firing pin moves forward. Once the bolt is in the forward position, a protrusion on the bolt carrier strikes the rear of the firing pin and begins to propel it forward. At the same time, the widened middle part of the firing pin, acting from the inside on the rear parts of the lugs, moves them apart into the grooves of the receiver, rigidly locking the bolt. After the shot, the bolt frame begins to move backward under the action of the gas piston. In this case, the firing pin is pulled back, and special bevels bring the lugs together, disengaging them from the receiver and unlocking the bolt. The return spring was located under the barrel and, under intense fire, overheated and lost its elasticity, which was one of the few disadvantages of the DP machine gun.
The food was supplied from flat disk magazines - “plates”, in which the cartridges were arranged in one layer, with bullets towards the center of the disk. This design ensured reliable supply of cartridges with a protruding rim, but also had significant drawbacks: large dead weight of the magazine, inconvenience in transportation and the tendency of magazines to be damaged in combat conditions. The machine gun's trigger allowed only automatic fire. There was no conventional safety; instead, an automatic safety was located on the handle, which turned off when the hand covered the neck of the butt. The fire was fired from fixed folding bipods.
The Degtyarev light machine gun (RPD) was developed in 1944 and became one of the first models adopted for service in the USSR for the then new 7.62x39 mm cartridge. From the early 1950s to the mid-1960s, the RPD served as the main fire support weapon at the infantry squad level, complementing the AK assault rifles and SKS carbines that were in service. Since the mid-1960s, the RPD has been gradually replaced by the RPK light machine gun, which was good from the point of view of unifying the small arms system in the Soviet Army, but somewhat reduced the fire capabilities of the infantry. However, RPDs are still stored in Army Reserve warehouses. In addition, the RPD was widely supplied to countries, regimes and movements “friendly” to the USSR, and was also produced in other countries, including China, under the designation Type 56.
The RPD is an automatic weapon with an automatic gas engine and belt feed. The gas engine has a long stroke piston located under the barrel and a gas regulator. The barrel locking system is a development of Degtyarev's earlier developments and uses two combat cylinders, movably mounted on the sides of the bolt. When the bolt comes to the forward position, the protrusion of the bolt frame pushes the combat cylinders to the sides, bringing their stops into the cutouts in the walls of the receiver. After the shot, the bolt frame, on its way back, with the help of special shaped bevels, presses the larvae to the bolt, disengaging it from the receiver and then opening it. The fire is carried out from an open bolt, the fire mode is automatic only. The barrel of the RPD is not replaceable. The cartridges are fed from a solid metal belt for 100 cartridges, made up of two pieces of 50 cartridges each. Standardly, the tape is located in a round metal box suspended under the receiver. The boxes were carried by the machine gun crew in special pouches, but each box also has its own folding handle for carrying. A folding, non-removable bipod is located under the muzzle of the barrel. The machine gun was equipped with a carrying belt and allowed firing “from the hip”, while the machine gun was located on the belt, and the shooter held the weapon in the line of fire with his left hand, placing left palm on top of the forend, for which the forend was given a special shape. The sights are open, adjustable for range and elevation, the effective firing range is up to 800 meters.
In general, the RPD was a reliable, convenient and fairly powerful fire support weapon, anticipating the later fashion for belt-fed light machine guns (type M249 / Minimi, Daewoo K-3, Vector Mini-SS, etc.)
Heavy machine gun Degtyarev - Shpagina DShK DShKM 12.7 (USSR)
The task to create the first Soviet heavy machine gun, intended primarily to combat aircraft at altitudes of up to 1500 meters, was issued to the already very experienced and well-known gunsmith Degtyarev in 1929. Less than a year later, Degtyarev presented his 12.7mm machine gun for testing, and in 1932, small-scale production of the machine gun began under the designation DK (Degtyarev, Large-caliber). In general, the DK was similar in design to the DP-27 light machine gun, and was fed from detachable drum magazines with 30 rounds of ammunition, mounted on top of the machine gun. The disadvantages of such a power supply (bulky and heavy magazines, low practical rate of fire) forced the production of the recreational weapon to cease in 1935 and to begin its improvement. By 1938, designer Shpagin developed a belt feed module for the recreation center, and in 1939 the improved machine gun was adopted by the Red Army under the designation “12.7mm heavy machine gun Degtyarev - Shpagin model 1938 - DShK.” Mass production of DShK began in 1940-41. They were used as anti-aircraft weapons, as infantry support weapons, and installed on armored vehicles and small ships (including torpedo boats). Based on the experience of the war, in 1946 the machine gun was modernized (the design of the belt feed unit and barrel mount were changed), and the machine gun was adopted under the designation DShKM.
The DShKM was or is in service with over 40 armies around the world, produced in China (“type 54”), Pakistan, Iran and some other countries. DShKM machine gun used as an anti-aircraft gun Soviet tanks post-war period (T-55, T-62) and on armored vehicles (BTR-155). Currently, the DShK and DShKM machine guns have been almost completely replaced in the Russian Armed Forces. heavy machine guns“Utes” and “Kord”, more advanced and modern.
In the mid-1950s, the Soviet Army began a program to develop a new set of small arms designed to replace the Kalashnikov AK assault rifle, SKS carbine and RPD light machine gun. The complex was supposed to include an assault rifle and a light machine gun (squad support weapon) that was maximally unified with it, both chambered for the 7.62x39 M43 cartridge. Based on the results of the competition in 1961, the SA adopted a modified Kalashnikov AKM assault rifle and a Kalashnikov RPK light machine gun, unified with it in design and magazines. The RPK remained the squad's main support weapon until 1974, when it was replaced by its counterpart chambered for 5.45x39, the RPK-74 light machine gun.
The Kalashnikov RPK light machine gun uses the same automation scheme and basic design solutions as the Kalashnikov AKM assault rifle, that is, gas-operated automatics with the barrel locked by turning the bolt. The receiver is stamped from sheet steel, more durable than the AKM receiver to increase service life. The barrel is longer than the AKM and cannot be replaced in case of overheating. The trigger mechanism is completely similar to that of the AKM, it allows firing in single shots and bursts, firing is carried out from a closed bolt. Ammunition is fed from detachable magazines compatible with AK/AKM assault rifles. For the RPK, two types of high-capacity magazines were additionally developed and put into service - a box-shaped (horn) magazine with 40 rounds and a drum magazine with 75 rounds. Early versions of box magazines were made of steel, later ones were made of plastic. Drum magazines had a steel structure and were characterized by the high cost and slowness of loading with cartridges. The RPK was equipped with a folding bipod mounted under the barrel, a specially shaped butt and a sight with the ability to introduce lateral adjustments. The RPKS variant, developed for airborne troops, had a side-folding stock. In addition, versions of the RPKN and SSBN were produced with a rail mounted on the receiver for attaching night sights.
Currently, based on the RPK-74M, the RPKM machine gun is produced under the 7.62x39 cartridge, intended primarily for export.
It should be noted that, as a light machine gun, the RPK had significant disadvantages - the low capacity of the power supply system, the inability to conduct intense automatic fire due to a non-replaceable barrel and firing from a closed bolt. Its main advantage was a high degree of unification with the standard AKM assault rifle, and a somewhat greater firing range and accuracy in comparison with it (due to a longer and somewhat heavier barrel).
The single MAG machine gun (Mitrailleuse d'Appui General (French) - Universal Machine Gun) was developed by the Belgian company FN (Fabrique Nationale) in the 1950s and very quickly gained almost worldwide popularity. A fairly simple and reliable design, combined with flexibility of use and adequate ammunition, has secured this machine gun a place in the weapons systems of over 50 countries, including Belgium itself, the UK, Australia, Canada, the USA, Sweden and many other countries. In many countries, including England and the USA, these machine guns are produced under license.
The FN MAG machine gun is built on the basis of gas-operated automatics, developed by John Browning for his automatic rifle BAR M1918, with the only difference being that the locking unit of the FN MAG is turned “upside down” relative to the M1918, and the magazine feed is replaced with a belt feed, made like the German one MG-42 machine gun. The gas outlet unit is located under the barrel and has a gas regulator to control the rate of fire and adapt to external conditions. Locking is carried out using a special swinging lever mounted on the bolt and connected to the gas piston rod. When locked, the lever rotates downward, engaging with a stop in the bottom of the receiver and thereby supporting the bolt from behind.
The barrel of the machine gun is quick-changeable, it has a carrying handle used when replacing a hot barrel, as well as a flash hider and a front sight on a high base. The feed is carried out from a metal strip (usually loose), and the cartridges are fed directly into the chamber.
The basic version of the machine gun is equipped with a lightweight folding bipod on a gas block, a pistol grip with a trigger, and a butt (wooden or plastic). At the bottom of the receiver, made of stamped steel parts, there are mounts for installing the machine gun on infantry machines or equipment. There is an open sight on the top of the receiver; on machine guns latest issues a Picatinny-type rail can also be installed, allowing the installation of any optical and night sights with appropriate mounts.
The NK 21 machine gun was developed by Heckler-Koch (Germany) in the early 1960s on the basis of the automatic G3 rifle as a universal weapon, suitable for use both as a light machine gun (from a bipod), and as an easel machine gun - from equipment or a tripod machine . Subsequently, based on this machine gun, a number of other models and modifications were developed, including the 5.56mm HK 23 machine gun (created in the late 1970s for the American competition for the SAW light machine gun), as well as the HK 11 light machine guns of 7.62x51 caliber and HK 13 of 5.56 caliber mm. HK21 series machine guns are produced under license in Portugal and Greece; they were supplied to a number of African, Asian and Latin American countries. Since the beginning of the 2000s, production of all machine guns in the HK 21 / HK23 line has ceased in Germany.
Based on the experience of the Second World War, Soviet military experts appreciated the German idea of a universal (or single) machine gun, and set the task of creating such a machine gun for the Soviet army. The first experimental designs, begun in the late 1940s, used pre-existing designs such as the RP-46 or SGM as a base, but they were considered unsuccessful. Only by 1957 did a fundamentally new model appear, which more or less satisfied the army’s requirements - a single Nikitin machine gun. This was an original development that used automatic gas release with automatic adjustment and a specially designed belt with an open link, which ensured simple straight-line feeding of the cartridge into the barrel. In 1958, a decision was made to produce a large batch of Nikitin machine guns for military testing, but almost at the same time, the GRAU General Staff of the USSR decided on the need to “accelerate” the process of fine-tuning the PN, for which it ordered a similar machine gun from M.T. Kalashnikov’s design group. It should be noted that just at this time Kalashnikov was busy fine-tuning the AKM / RPK complex, but he still accepted the challenge. According to the test results, the hastily created Kalashnikov machine gun was recognized as superior to the Nikitin machine gun (the decision to adopt and produce it had already been practically made), and in 1961 it was the Kalashnikov machine gun that was adopted for service. This machine gun was created in four versions at once, which had the same basic mechanisms and design - a manual PK (on a bipod), an easel PKS (on a machine designed by Samozhenkov), an armored personnel carrier PKB and a tank PKT (with an elongated heavy barrel and a remote electric trigger). Based on operational experience among the troops, the basic design of the machine gun was modernized by slightly lightening and strengthening the parts, as well as by switching to a lighter universal infantry machine designed by Stepanov. In 1969, a new family of PKM / PKMS / PKMB / PKMT machine guns entered service with the Soviet army, and to this day these machine guns are the main ones in the Armed Forces of Russia and many countries - former republics of the USSR. The production of copies of PKM (with or without a license) has been established in Bulgaria, China, Iran, and the former Yugoslavia.
Machine guns of the PK / PKM series are highly reliable and enjoy deserved popularity among the troops, despite the somewhat overcomplicated two-stage system for feeding cartridges from the belt to the barrel.
The Kalashnikov machine gun uses gas-operated automatics with a long-stroke gas piston located under the barrel. The barrel is quick-change and has a carrying handle, also used for hot barrel replacement. The gas outlet unit is equipped with a manual gas regulator. The barrel is locked by turning the bolt. The cartridges are fed from a solid metal strip with a closed link. The tapes are assembled from pieces of 50 links using a cartridge. The standard capacity of the belts is 100 (in the manual version) or 200 (in the easel version) cartridges. The direction of feed of the tape is from right to left, the windows for feeding and exiting the tape are equipped with dust-proof covers, as is the window for ejecting spent cartridges. The supply of cartridges from the belt is two-stage - first, a special gripper, when the bolt frame is rolled back, pulls the cartridge out of the belt back, after which the cartridge is lowered onto the chambering line and, when the bolt rolls back, is sent into the barrel. Shooting is carried out from an open bolt, with automatic fire only. Standard infantry controls include a pistol grip, trigger, manual safety, and frame stock. In the armored personnel carrier version, it is possible to install a special butt plate with paired handles and a trigger button instead of a butt, in the tank version, an electric remote trigger mechanism is used. In the infantry version, the machine gun is equipped with a folding bipod; in the easel version, a universal tripod machine with an adapter for anti-aircraft shooting is additionally used.
The Pecheneg light machine gun was developed at the Central Research Institute of Precision Engineering (Russia) as a further development of the standard army PKM machine gun. Currently, the Pecheneg machine gun has passed army tests and is in service with a number of army and Ministry of Internal Affairs units participating in the anti-terrorist operation in Chechnya. In general, reviews of the new machine gun from the troops are positive. Due to the lack of a replaceable barrel, the machine gun became more mobile and, therefore, more suitable for modern combat operations.
The main task when creating the Pecheneg was to increase the efficiency of fire and get rid of such a drawback of most modern single machine guns as the need for a replaceable barrel. The result of the work of TsNIITochMash was the creation of a barrel with forced ejection air cooling of the barrel. The Pecheneg barrel has specially designed external fins and is enclosed in a metal casing. When firing, powder gases coming out of the barrel at high speed create the effect of an ejection pump in the front part of the casing, drawing cold air along the barrel. Air is taken from the atmosphere through windows in the casing, made under the carrying handle, in the rear part of the casing. Thus, it was possible to achieve a high practical rate of fire without the need to replace the barrel - the maximum length of a continuous burst from a Pecheneg is about 600 shots - that is, 3 boxes with belts of 200 rounds of ammunition, or a standard portable ammunition load. When conducting a long battle, the machine gun can fire up to 1000 rounds per hour without deteriorating combat characteristics and reducing the barrel life, which is at least 30,000 rounds. In addition, due to the enclosure of the barrel in the casing, thermal moire (oscillations of hot air over a heated barrel during intense fire), which interfered with accurate aiming, disappeared. Another modification in relation to the PKM was the relocation of the bipod under the muzzle of the barrel. This was done to increase the stability of the machine gun when firing from a bipod, however, this position of the bipod is not always convenient, as it limits the sector of fire along the front without moving the shooter and/or weapon.
In general, the Pecheneg retained up to 80% of the common parts with the PKM (receiver with all mechanisms, machine), and the increase in fire efficiency ranged from 150% when firing from a machine to 250% when firing from a bipod (according to the developers).
The development of large-caliber machine guns chambered for particularly powerful 14.5mm cartridges, originally created in the USSR for anti-tank rifles, began in 1942 in response to numerous military requirements. The main purpose of such a heavy machine gun was to combat lightly armored enemy vehicles (light tanks and armored personnel carriers), unarmored ground vehicles and enemy aircraft. In 1944, it was decided to develop the design of the machine gun proposed by Vladimirov, but the fine-tuning of the machine gun and installations for it was delayed and Vladimirov’s heavy machine gun was adopted for service only in 1949, in the version of an infantry machine gun on a Kharykin wheeled machine (under the designation PKP - Heavy Infantry Machine Gun Vladimirov system), as well as in the anti-aircraft version on several land and sea installations, which each had one, two or four Vladimirov machine guns. In 1955, a tank version of the Vladimirov KPVT machine gun appeared, which replaced the KPV / PKP in production and was used both for arming armored vehicles (BTR-60D, BTR-70, BRDM) and in anti-aircraft machine gun mounts ZPU-1, ZPU-2 and ZPU-4 . The anti-aircraft version of the KPV was used during combat operations in Vietnam, in addition, these machine guns were widely used Soviet troops in Afghanistan and during the Chechen campaigns. Copies of KPV machine guns were produced under license in Poland and China.
Until recently, Vladimirov’s heavy machine gun was the most powerful weapon in its class (caliber less than 20mm), but several years ago China developed its own version of the machine gun chambered for the original 14.5x115 cartridge. Thanks to a powerful cartridge with an armor-piercing bullet weighing 60 grams and an initial speed of 1030 m/s (muzzle energy of about 32,000 Joules), the KPV penetrates 32 mm of steel armor at a range of 500 meters and 20 mm of armor at a range of 1000 meters.
The Vladimirov KPV-14.5 heavy machine gun uses automatic operation using recoil energy with a short barrel stroke. The barrel is locked at the moment of firing by rotating the clutch attached to the bolt; the inner surface of the coupling has lugs in the form of segments of intermittent threads, which, when rotated, engage with the corresponding lugs on the breech of the barrel. The rotation of the coupling occurs when the transverse pin interacts with the shaped cutouts in the receiver. The barrel is quick-changeable, enclosed in a perforated metal casing and removed from the body of the machine gun along with the casing, for which there is a special handle on the casing. The cartridges are fed from a metal strip with a closed link, assembled from loose pieces for 10 cartridges each. The pieces of tape are connected using a chuck. The standard belt capacity is 40 cartridges for PKP and 50 for KPVT. The supply of cartridges from the belt to the barrel is carried out in two steps - first, a special extractor on the bolt rollback removes the cartridge from the belt back, after which the cartridge is lowered to the chambering line and is sent into the barrel during the retraction of the bolt. Spent cartridges are ejected downward and forward through a short tube on the receiver; The spent cartridge case is pushed out of the grooves holding it on the shutter mirror by the next cartridge or a special lever - the rammer (for the last cartridge in the belt). Shooting is carried out from an open bolt, with automatic fire only. The trigger mechanism is usually located on a machine or installation; in the infantry version, the controls on the machine include two vertical handles and a trigger button between them; in a tank machine gun, it is equipped with a remote electric trigger.
The Kord heavy machine gun was created at the Kovrov plant named after. Degtyarev (ZID) in the 1990s to replace the NSV and NSVT machine guns in service in Russia. The name “Kord” itself comes from the phrase “Design of the Degtyarev gunsmiths.” The main reason for the development of the Kord machine gun was the fact that the production of NSV machine guns after the collapse of the USSR ended up on the territory of Kazakhstan. In addition, when creating the Kord, the goal was to increase the shooting accuracy compared to the NSV-12.7. The new machine gun received the index 6P50 and was adopted by the Russian army in 1997. Serial production was launched at the ZID plant in 2001. Currently, Kord machine guns are used both as infantry support weapons and are installed on armored vehicles, in particular on T-90 tanks. In addition, due to the compatibility of Kord and NSV / NSVT machine guns in terms of attachments to installations, it is possible to replace NSVT machine guns that have exhausted their service life on the vehicle with new Kord without any modifications to the installations.
The Kord large-caliber machine gun uses gas-operated automatics with a long working stroke of the gas piston located under the barrel. The machine gun's barrel is quick-change, air-cooled, and on newer machine guns it is equipped with an effective muzzle brake. The barrel is locked using a rotating bolt. The design of the machine gun provides a special buffer for moving parts, which, in combination with a muzzle brake, significantly reduces the peak recoil of the weapon when firing. Shooting is carried out from an open bolt. The cartridges are fed from a non-scattered metal strip with an open (unclosed) link from an NSV machine gun. The tape is assembled from pieces of 10 links using a cartridge. Feeding cartridges from the belt directly into the barrel. The normal direction of movement of the tape is from right to left, but it can easily be reversed.
Of the controls on the body of the machine gun, there are only a trigger lever and a manual safety. Fire controls are located on the machine or installation. In the infantry version, they include a pistol grip with a trigger and a bolt cocking mechanism mounted on the cradle of the 6T7 machine. Additionally, the infantry machine is equipped with a folding stock with a built-in spring recoil buffer.
The Minimi machine gun was developed by the Belgian company FN Herstal in the mid-late 1970s and early 1980s and has been in mass production since approximately 1981. It is in service with many countries, including Belgium itself, the USA (designated M249 SAW), Canada (designated C9), Australia (designated F-89) and many others. The machine gun enjoys well-deserved popularity for its high mobility combined with firepower, significantly superior to the firepower of such light machine guns as RPK-74, L86A1 and others, built on the basis of machine guns, and not created “from scratch” like machine guns. Distinctive feature Minimi - the ability to use both metal tape (standard method) and NATO standard rifle magazines (from the M16 rifle, reserve version) for shooting without any changes in design (the Czech Vz.52 light machine gun, created 30 years earlier, had a similar capability ). Minimi machine guns are used to increase the firepower of infantry squads, providing effective fire at ranges of up to 600-800 meters, combined with high mobility.
Minimi is a light (light) machine gun, built on the basis of gas-operated automatics; the barrel is locked by turning the bolt. Feed - metal loose belt or box magazines (magazine receiver is located on the left side of the weapon under the belt receiver, the magazine is inserted at an angle of approximately 45 degrees down from the horizontal). When using tape, the magazine receiver window is covered with a dust-proof curtain; when inserting a magazine (with the tape removed), the open curtain blocks the tape feed path. When using a belt, part of the gas engine's energy is spent on pulling the belt, so with a belt the fire rate is lower than with a store-fed one. The tape is usually fed from plastic boxes or canvas “bags” on a metal frame, adjacent to the machine gun from below, with a capacity of 100 or 200 rounds.
The machine gun barrel is quick-changeable, equipped with a flash suppressor and a folding handle for carrying. Barrels are produced in three main sizes - standard 465 mm long, “landing” 349 mm long and “special purpose” 406 mm long. The bipod is foldable and is located under the barrel on the gas outlet tube.
Depending on the country of manufacture and modification, Minimi may have stocks and forends of various designs, mounts for optical and night sights, etc. Fire control - using a pistol grip with a trigger, fire mode - automatic only.
When creating families of small arms, their manufacturers primarily focus on a certain basic version (most often an assault rifle and its weapon), which is usually known to the general public. For example, when talking about the Steyr AUG, we first of all remember the assault rifle. And only then will we talk about modifications of a carbine, machine gun or submachine gun. However, we should not forget that many types of weapons, primarily known for their basic versions, are also actively used in modifications.
Thus, the modular rifle complex, known as the “army universal rifle” (“Armee Universal Geweh” or AUG), produced by the Austrian arms company Steyr-Mannlicher AG, is associated primarily with the famous assault rifle of the same name. However, we should not forget about other AUG variants, such as the Steyr AUG H-Bar light machine gun. As is clear from the name of the machine gun itself, this weapon is equipped with a long, heavy barrel (elongated by more than 100 mm compared to the basic assault rifle). The AUG H-Bar light machine gun is designed to be used as a fire support weapon for a rifle infantry squad. It should be noted that the Steyr AUG H-Bar light machine gun is fundamentally no different from the Steyr AUG assault rifle and can be easily modified by replacing the long barrel with a standard one (508 mm long). In addition to the barrel, the main differences of the AUG Heavy-Barreled Automatic Rifle are the extended magazine with a capacity of 42 rounds (the capacity of a rifle magazine is 30 rounds) and the presence of a folding bipod. This weapon is produced by Steyr-Mannlicher AG as an independent model, and as one of the modules of the Steyr AUG assault rifle.
As for the principles of automation, the general layout and principles of operation of the Steyr AUG H-Bar machine gun, they are absolutely identical to the principles of the Steyr AUG assault rifle. At the moment, two versions of this light machine gun are produced: the Steyr AUG H-Bar itself and the Steyr AUG H-Bar/T. The first option is equipped with a handle for carrying weapons with an optical sight built into it (close to the handle of the Steyr AUG A1). In the AUG H-Bar/T version, the machine gun is equipped with a special rail (bridge) designed for mounting various night and/or optical sights. At special needs, both versions of the light machine gun can be converted to fire from the rear sear. In this case, a new trigger assembly (trigger mechanism) is mounted into the weapon butt module. In addition, the bolt frame module is equipped with a new handle. However, firing from the rear sear does not affect the main characteristics of the weapon.
The Steyr AUG H-Bar light machine gun fully possesses all the advantages (however, also disadvantages) of the bullpup system and, like the Steyr AUG assault rifle, is one of the very interesting examples of modern small arms.
The HK MG-43 light machine gun has been developed by the famous German company Heckler-Koch since the second half of the 1990s, and its prototype was first shown to the general public in 2001. The new machine gun has become a direct competitor to such a popular model as the Belgian FNMinimi / M249 SAW, and is intended for the same role - a light and mobile fire support weapon at the infantry squad level. This machine gun was adopted by the Bundeswehr (German Army) in 2003 under the designation MG4, and in 2007 the first export contract was concluded with Spain. In the German army, the MG4 is gradually replacing the heavier, but also more powerful, single MG3 7.62mm NATO machine gun used in the light duty role.
Like the HK G36 rifle from the same company, the HK MG4 machine gun marks the transition of Heckler-Koch from systems based on semi-blowback automatics with roller braking to systems with gas-operated automatics.
The HK MG4 machine gun is a belt-fed, gas-operated, air-cooled barrel automatic weapon. The gas piston is located under the barrel and is rigidly connected to the bolt frame, on which the rotary bolt is located. On the top of the bolt frame there is a roller that drives the tape feed mechanism. The machine gun's barrel is quick-changeable, equipped with a flash suppressor and a folding handle for carrying and changing the barrel. The machine gun is fed using a standard loose belt, which is fed from the left side of the weapon. A special box can be attached to the machine gun, containing a belt for 100 or 200 rounds. Ejection of empty tape links to the right, spent cartridges - down. The HK MG4 machine gun can only fire automatically; the ambidextrous safety is located above the pistol grip. Shooting is carried out from an open bolt. The charging handle is located on the right. The machine gun has a plastic butt folding to the left, a lightweight plastic fore-end and a folding bipod mounted on a gas outlet block. In addition, it has mounts for installation on equipment or an infantry machine. Sights include a front sight on a folding base and an adjustable, quick-release rear sight mounted on a Picatinny rail on the receiver cover. The rear sight is graduated from 100 to 1000 meters; instead of it (or together with it), it is possible to install various day and night sights with standard mounts.
Due to the obsolescence of the MG 3 7.62mm NATO single machine guns in service with the Bundeswehr (German Army) (the production of which in Germany has long been discontinued), in 2009 the well-known German company HecklerundKoch introduced its new experimental single machine gun HK 121 under cartridge 7.62x51 NATO. This machine gun was developed on the basis of the 5.56mm HK 43 / MG 4 light machine gun, and in 2013 it was adopted by the Bundeswehr and received the official designation MG5
The HK 121 / MG5 machine gun uses gas-operated automatics; a gas piston with a long stroke is located under the barrel. The design includes a manual gas regulator. The barrel is locked by a rotary bolt with two lugs. The barrel of the air-cooled machine gun is quick-changeable, equipped with a flash suppressor and a folding handle for carrying and changing the barrel. The HK121 machine gun fires from an open bolt, with automatic fire only.
The machine gun is powered by a loose metal belt with an open link, which is fed from the left side of the weapon. On the left side of the receiver, a round plastic cartridge box from the MG3 can be fed to the machine gun, holding a 50-round belt, or the belt can be fed from separate boxes with a capacity of 200 rounds.
The NK 121/MG5 machine gun has a plastic butt folding to the left and a folding bipod mounted on a gas outlet block. Under the gas piston tube there is a plastic folding handle (for hand-held shooting), which when folded forms a small fore-end. In addition, the machine gun has standard mounts for installation on vehicles or infantry vehicles from the MG 3. Sights include a front sight on a folding base and an adjustable quick-release rear sight mounted on a Picatinny-type rail on the receiver cover. Various day and night optical sights can also be mounted on the same rail.
The light (light) machine gun “7.62mm KvKK 62” (‘Kevyt KoneKivaari’, Finnish for “light machine gun”) was developed by Valmet since the late 1950s to replace the outdated Lahti-Saloranta LS-26 machine gun. The first prototypes of the KvKK 62 machine guns appeared in 1960, in 1962 it was adopted by the Finnish Army (Finnish Self-Defense Forces, SSF), deliveries to the troops began in 1966. The KvKK 62 is still in service with the SSF and was also supplied to Qatar. Currently in Finland there are plans to partially replace the KvKK 62 with single PKM machine guns purchased from Russia, as they provide greater firepower and reliability.
KvKK 62 is built on the basis of automation with a gas engine. The fire is fired from an open bolt, locking is carried out by tilting the bolt upward, behind the receiver cover. The receiver is milled from steel, the return spring is located in a hollow metal butt. Food is supplied from canvas round bags (with a metal frame) adjacent to the machine gun on the right. Each bag holds 100 rounds of metal belt. Extraction of spent cartridges - downwards, the window for ejecting cartridges is located under the tape receptacle.
In general, the KvKK 62 has a rather clumsy appearance, largely due to the primitive-shaped pistol grip without a trigger guard and the metal butt, to which a long ramrod is attached to the outside right. The machine gun has a side-folding carrying handle located in front of the tape receiver, and a folding bipod under the barrel, as well as fastenings on the lower part of the receiver for installation on vehicles. It should be noted that the absence of a trigger guard (it is replaced by a vertical bar in front of the trigger) is caused by the need to ensure shooting in winter, when soldiers wear thick gloves or mittens.
Among the advantages of the machine gun (according to user reviews) it is necessary to note the high accuracy of burst fire, low recoil, interchangeability of ammunition with standard Finnish machine guns, and high rate of fire. The disadvantages are, first of all, increased (compared to machine guns) sensitivity to contamination and moisture getting inside the weapon, and the lack of a quick-change barrel, which does not allow more or less continuous automatic fire. In addition, the KvKK 62 is somewhat heavy for its combat characteristics.
Light machine gun L86A1 - SA-80 Light Support Weapon (UK)
The L86A1 light machine gun was developed in Great Britain as an integral part of the SA-80 program, which included the IW assault rifle and the LSW light machine gun, built on a single “platform” with maximum unification of components. Initially, development was carried out for the experimental English cartridge of 4.85x49mm caliber; after the adoption of the Belgian version of the SS109 5.56x45mm cartridge as a NATO standard in the late 1970s, further developments were carried out for it. The machine gun was ready by 1989, and began to enter service under the designation L86A1. Need to say. that the machine gun inherited all the problems and troubles of the L85A1 assault rifle, including low reliability, inconvenience in handling, and so on. Due to its low reliability, this “machine gun” could actually be used more as an ersatz sniper rifle, thanks to a long, heavy barrel and a good optical sight. Even with reliability issues, the lack of a quick-change barrel and low magazine capacity significantly limited the L86A1's capabilities as a support weapon. And if the problems of the L85A1 rifle were solved by a serious modernization to the L85A2 configuration, then the machine guns, produced in much smaller numbers, were not modified. Instead, the British Armed Forces are purchasing FN Minimi machine guns, which will take on the role of squad-level fire support weapons. The L86A1 weapon will also remain in service with the troops for the time being to provide targeted shooting with single shots and short bursts at ranges inaccessible to the L85A2 assault rifles and Minimi machine guns, which have a shorter barrel.
Multi-barreled machine gun M134 / GAU-2/A ‘Minigun’ (Minigun) (USA)
Development multi-barreled machine gun 7.62mm caliber was launched by the American company General Electric in 1960. These works were based on the M61 Vulcan 20mm 6-barreled aviation cannon, created by the same company for the US Air Force on the basis of the Gatling gun multi-barrel canister system. The first experimental six-barreled machine guns of 7.62mm caliber appeared in 1962, and already in 1964 such machine guns were installed on the AC-47 aircraft to fire perpendicular to the aircraft’s course (from the windows and doors of the fuselage) at ground targets (North Vietnamese infantry). Based on the successful use of new machine guns, called ‘Minigun’, General Electric launched their mass production. These machine guns were adopted under the designations M134 (US Army) and GAU-2/A (US Navy and Air Force). By 1971, there were already more than 10 thousand Miniguns in the US Armed Forces, most of which were installed on helicopters operating in Vietnam. A number of Miniguns were also installed on small river vessels of the US Navy, which operated in Vietnam, including in the interests of special forces.
Due to their high density of fire, Miniguns proved to be an excellent means of suppressing lightly armed North Vietnamese infantry, but the need for electrical power and the very high consumption of ammunition limited their use mainly to vehicles. Some time after the end of the Vietnam War, the production of Miniguns was practically curtailed, but the involvement of the United States in a number of conflicts in the Middle East since the early 1990s led to the fact that the production of modernized versions of the machine gun, designated M134D, was launched under license from the American company Dillon Aero . New machine guns are installed on helicopters, ships (on light special forces support boats - as a means of fire support, large ships - as a means of protection against high-speed boats and enemy boats), as well as on jeeps (as a means of fire suppression to combat ambushes, etc. .).
It is interesting that the photos of Miniguns on infantry tripods in most cases have nothing to do with military service. The fact is that in the United States, in principle, ownership of automatic weapons is permitted, and a number of citizens and private companies own a number of Miniguns produced before 1986. These machine guns can be seen at periodically organized shooting events for everyone, such as Knob Creek machine gun shot.
As for the possibility of shooting from the M134 in Hollywood style - i.e. from the hands, then here (even ignoring the weight of the weapon and its ammunition) it is enough to remember that the recoil force of the M134D Minigun machine gun at a rate of fire of “only” 3,000 rounds per minute (50 rounds per second) averages 68 kg , with a peak recoil force of up to 135 kg.
The M134 'Minigun' multi-barreled machine gun uses automation with external drive mechanisms from a DC electric motor. As a rule, the engine is powered from the carrier's on-board network with a voltage of 24-28 Volts with a current consumption of about 60 Amps (M134D machine gun at a rate of fire of 3000 rounds per minute; power consumption of about 1.5 kW). Through a gear system, the engine rotates a block of 6 barrels. The firing cycle is divided into several separate operations carried out simultaneously on different barrels of the block. The cartridge is usually fed into the barrel at the upper point of rotation of the block; by the time the barrel reaches its lowest position, the cartridge has already been completely loaded into the barrel and the bolt is locked, and a shot is fired in the lower position of the barrel. When the barrel moves up in a circle, the spent cartridge case is extracted and ejected. The barrel is locked by turning the bolt cylinder; the movement of the bolts is controlled by a closed curved groove on the inner surface of the machine gun casing, along which the rollers located on each bolt move.
Based on the German experience in creating and using single machine guns accumulated during the Second World War, immediately after its end the US Army began searching for its own version of a single machine gun. The first experiments were carried out under the .30-06 cartridge, but soon the army switched to the new T65 cartridge, for which an experimental T161 single machine gun was created, based on German developments (the FG42 rifle and the MG42 machine gun). In 1957, a modified version of the T161E2 was adopted by the US Army and Navy under the designation M60. At first glance, it was a very promising and powerful weapon, but in an effort to create a machine gun suitable for the role of a manual one, its creators overly lightened the design and made a number of engineering mistakes. As a result, the machine gun turned out to be not very reliable, it periodically disassembled itself due to vibration when firing, allowed incorrect assembly of the gas outlet unit, and when parts were worn out or broken, it had a tendency to spontaneously fire. Due to the placement of the bipod on the barrel, changing a hot barrel became quite inconvenient. In short, the machine gun turned out to be unsuccessful, which did not prevent it from becoming the main support weapon for the American infantry during the Vietnam War and a number of subsequent, smaller operations. In addition to the United States, M60 machine guns were supplied to El Salvador, Thailand and a number of other countries that received American military assistance. It must be said that a number of shortcomings of the M60 machine gun were soon corrected in the M60E1 variant, but for unknown reasons this version was never put into production. But on the basis of the M60, variants were created for arming armored vehicles and helicopters.
The LW50MG light heavy machine gun, being developed by General Dynamics, is a development American program XM-307ACSW / XM-312, which has recently experienced financial difficulties. In fact, the LW50MG machine gun has become a simplified and cheaper version of the XM-312 machine gun, having lost the ability to change the caliber, the direction of feed of the belt and received simplified sighting devices. This machine gun is currently being tested by the US Army, and current plans call for it to enter service in 2011. According to the same plans, the LW50MG light machine guns will have to complement the significantly heavier Browning M2HB machine guns of the same caliber in the mobile units of the US Armed Forces: airborne, mountain troops and special forces.
A distinctive feature of the new machine gun, in addition to its low weight, is what American testers say is its very high shooting accuracy, which allows it to effectively hit relatively small targets at ranges of up to 2,000 meters. Thanks to this, the new machine gun can become, among other things, an effective means of combating enemy snipers or individual shooters hiding behind more or less light barriers.
The LW50MG heavy machine gun is a belt-fed automatic weapon with an air-cooled barrel. The machine gun barrel is quick-changeable. The automatic system operates according to a gas exhaust system; the barrel is locked by turning the bolt. In this case, the barrel, with the bolt box and gas outlet unit mounted on it, can move inside the machine gun body, forming a movable automation group. The movement of the moving group is limited by a special damper and a return spring. Feeding is carried out using a standard loose metal belt with any 12.7x99mm caliber cartridges, feeding the belt only from left to right.
In 1982, the US Armed Forces adopted the new M249 light machine gun (FNMinimi), but due to the “childish problems” inherent in all new systems, the introduction of M249 SAW machine guns into the troops did not go too smoothly. As a result, in 1986, ARES offered the military a new light machine gun, the Stoner 86 (Eugene Stoner worked closely with ARES at that time). This machine gun was a direct development of the old Stoner 63 system in the direction of simplifying and reducing the number of possible configuration options (up to two - a machine gun with a belt or magazine feed), as well as increasing reliability. The machine gun turned out to be quite successful, but neither the American military nor foreign buyers showed much interest in it. Continuing problems with the M249 SAW 5.56mm machine guns in the late eighties and early nineties prompted Stoner to further simplify the design of his Stoner 86 machine gun, and he, already working for KnightsArmament, created a new machine gun known as the Stoner 96. This machine gun is 5.56 caliber. mm had only belt power and, due to proper calculation of the automation, provided a small peak recoil, which, in particular, increased the efficiency of firing a machine gun from the hands, including in motion. The Knights Armament company has released a small series (about 50 units) of Stoner 96 machine guns, and is still trying to push them into service both in the United States and in other countries, however, so far without visible success.
The ARES Stoner 86 light machine gun uses gas-operated automatics with a long-stroke gas piston located under the barrel. Air-cooled barrel, quick-change. Shooting is carried out from an open bolt, with automatic fire only. The barrel is locked with a rotary bolt. The cartridges are fed from standard loose metal belts with an M27 link; alternatively, the receiver cover with the tape feed mechanism can be replaced with a cover with a receiver for box magazines (compatible with the M16 assault rifle). Since the sighting devices are located along the longitudinal axis of the weapon, the magazine receiver is not directed vertically upward, but at an angle to the left. The ARESStoner86 machine gun is equipped with a fixed tubular buttstock and folding bipod under the gas cylinder.
The Stoner 96 / Knights LMG light machine gun is structurally a simplified version of the Stoner 86 machine gun. It eliminates the possibility of magazine feeding and increases the reliability and survivability of the mechanisms. To increase the maneuverability of the weapon and reduce its weight, the machine gun barrel was shortened, and a sliding stock from the M4 carbine was installed. The receiver and fore-end have Picatinnyrail type guides. Instead of a conventional bipod, a vertical GripPod handle with built-in small retractable bipods is placed on the lower guide of the forend, ensuring stable holding of the machine gun both when shooting from hand and when shooting from a rest.
The 12.7mm QJZ-89 / Type 89 heavy machine gun was developed in the late 1980s as the most lightweight infantry support weapon, allowing for high mobility of the weapon (including when carried by the crew) in combination with the ability to operate against ground and air targets at the level of heavier analogues of the same caliber. Currently, the 12.7mm QJZ-89 heavy machine gun is being supplied to individual units of the PLA. It should be noted that this machine gun is one of the lightest in its class, being noticeably lighter than the Russian Kord machine gun and practically the same weight as the latest experimental American LW50MG machine gun of 12.7x99 caliber.
12.7mm QJZ-89 heavy machine gun uses automatic mixed type: to unlock the rotary bolt, a gas exhaust mechanism is used with direct exhaust of gases from the barrel bore to the bolt through a gas tube under the barrel, and to drive the automation, the recoil energy of the moving block (barrel and receiver) inside the weapon body is used. During a short rollback of the moving block, its energy is transferred to the bolt frame through the accelerator lever. This scheme makes it possible to significantly reduce the peak recoil force acting on the installation by “stretching” the recoil action of the shot over time. The machine gun is equipped with a quick-change air-cooled barrel. The cartridges are fed from a metal strip with an open link, and the machine gun can use both standard 12.7x108 caliber cartridges and cartridges developed in China with armor-piercing sub-caliber bullets. The machine gun's controls include a pistol grip with a trigger and a stock with a shock-absorber buffer. The machine gun is placed on a special lightweight tripod, allowing firing at both ground and air targets. Most often, the machine gun is equipped with an optical sight, although conventional sighting devices are also provided.
In 2008, the well-known military-industrial corporation Rheinmetall decided to return to the small arms market and began developing a large-caliber machine gun (chambered 12.7x99 NATO) with an external drive mechanism (from a built-in electric motor). This machine gun, created to meet the specific requirements of the Bundeswehr, is intended primarily for installation on armored vehicles and helicopters, including remote-controlled turrets. The main features of this system, which received the factory designation RMG 50, are light weight (25 kg versus 38 kg for the M2NV veteran of the same caliber), adjustable rate of fire, built-in shot counter, and dual cartridge supply system. In addition, to hit individual point targets, the machine gun has a so-called “sniper” firing mode, in which fire is fired in single shots from a closed bolt. In normal mode, automatic fire is fired from an open bolt. Another feature of this machine gun, which its creators rely on, is the particularly durable design of the barrel and locking unit, which allows it to use not only any standard 12.7x99 NATO cartridges, but also reinforced ammunition of the same caliber specially developed by Rheinmetall. It is assumed that such “reinforced” cartridges will be able to accelerate a standard 42-gram bullet to 1100 m/s or a heavier 50-gram bullet to 1000 m/s. At the time of writing these words (autumn 2011), the RMG 50 machine gun is planned for serial production and military testing by the German Army in 2013-14.
The Rheinmetall RMG 50 heavy machine gun uses an externally powered electric motor located at the rear of the receiver to drive the weapon mechanisms. The shutter is connected to the electric motor by a crank mechanism. Shooting can be carried out both from an open bolt (automatic fire) and from a closed one (single shots). Air-cooled barrel, quick-change. The supply of cartridges is double, switchable (on both sides of the receiver), using mechanisms driven by the main electric motor of the machine gun. The supply of cartridges is linkless, that is, the cartridges are fed from the boxes into the machine gun without the help of a belt, using special conveyors, the spent cartridges are returned back to the boxes in place of the spent cartridges. Thanks to the electronic control of the machine gun's electric drives, it is possible to smoothly adjust the rate of fire up to 600 rounds per minute, as well as firing modes in bursts of limited length with a cutoff for any desired number of shots (2, 3, 5, etc.) and a given rate in the burst. The machine gun in its basic version does not have any of its own sighting devices or fire controls, since it is intended to be used only from special installations or turrets.
The newest 7.62-mm infantry machine gun "Pecheneg-SP" (GRAU index - 6P69), created on the theme "Warrior" of the FSUE "TsNIITOCHMASH", was first presented at the exhibition "Rosoboronexpo-2014" in Zhukovsky in August 2014.
The Pecheneg-SP machine gun, unlike the basic Pecheneg (index 6P41), has an additional short barrel with a PMS (low-noise firing device), which provides increased mobility for a fighter when performing special operations in urban environments.
Additionally, the Pecheneg-SP received an ergonomic tactical fire control handle, which makes it easier to hold the machine gun when shooting while standing, and a stock that can be folded and adjusted in length. The machine gun also has a removable bipod, which can be installed both in the muzzle of the barrel (like the 6P41) and on the gas chamber (like the PKM). The receiver cover has a Picatinny rail for mounting optical and night sights.
To reduce clanging when moving with a machine gun, the entire inner surface of the box for the machine gun belt was covered with plastic. The aiming bar of the mechanical sight is marked up to 800 meters.
During war, technologies are always developed that are not in demand in peacetime. The armament of troops is constantly being improved, which, in turn, leads to the fact that inventors are constantly working to improve weapons for military forces.
The invention of the machine gun and its appearance on the battlefield dramatically changed the situation during combat operations.
From their first appearance to the present day, Russian machine guns have gone through a long evolution. At the beginning of their journey on the battlefields, machine guns had a narrow specialization. Now it is difficult to imagine a combat operation without the use of machine guns.
Manual Kalashnikov
The production of these weapons was stopped due to the cessation of production of military products at Kovrov Fur. factory in 1996.
The AEK-999 device itself is identical to the PKM. The differences from it were a new barrel and a body kit, which allows the installation of low-noise firing devices, flame arresters, etc.
This machine gun makes it possible to conduct intense fire without the need to change the barrel. Although this feature has been retained in the machine gun as an option not only for replacing the barrel, but also for its cleaning and maintenance.
In addition, there is a plastic fore-end on the barrel for hand-held firing on the move.
Now you can see that the development of small arms, including machine guns, for the Russian army is ongoing and does not stop to this day, and Russia’s combat power is replenished not only with new missile weapons, but also with various small arms systems.
