Installing a collimator on a double-barreled shotgun. Optical sights for carbine. Installation and configuration

For hunters and sports shooting enthusiasts who want to increase the efficiency of their weapons and improve combat accuracy, a collimator is best suited for “tuning”. It is the collimator sight for 12 gauge fishing weapons that is the most rational option for an optical device. Aiming is done by simply pointing the marker beam at the target, which significantly increases the speed of preparation and shooting itself. The shooter's eye is at a safe distance from the device, which eliminates injury from recoil. And for novice hunters, you can’t imagine a better assistant. Such sights provide comfortable shooting for people with limited

Collimator sight for smoothbore weapons

This type of sight is an electronic optical device. Refers to low frequency devices. For most production samples it is equal to one. The brand is projected onto the front lens (output screen) of the device. The mark itself can have different shapes: be in the form of a circle, a square or intersecting lines. Each option is designed for a specific firing distance: up to 100 meters, up to 400 and more than 400 meters. The color of the stamp can be red or green. Ease of use lies in the fact that the device does not block the target, transmits light and transmits a clear image.

Types and types of sights

Depending on the brand of the device, lighting methods can be active, if they use energy, or passive. Active ones allow you to shoot accurately in the dark and in bad weather conditions. Active stereoscopic ones project a mark for only one right eye. Passive ones can only be used during daylight hours; their brand is not bright and does not have contrast.

Sights are produced in two types: in the form of a tube, resembling optics in appearance, or in the form of a frame with a front lens. The tube consists of an LED emitter and two or more lenses. This device is more compact and lighter compared to classical optics, but slightly larger than an open-type device. The advantage is good visibility of the tag in bright sunlight. All elements are reliably protected by a durable case from shaking during shooting. A closed red dot sight for 12 gauge is not entirely convenient, since this type of weapon is most often used when shooting from an unstable position.

Open type devices have better visibility when shooting and significantly less weight. However, it is difficult to use them even during light precipitation. A variation is the halogen sight, although some experts classify it as a separate type of equipment. Externally, it resembles the frame of an open device. However, the brand image is projected onto the output screen by a laser beam. Depending on the hunting conditions, the screen plate can be quickly replaced. Can be used in any weather and in fog.

Features of use

Application practice shows that the sighting device is best installed on a quick-release console. If necessary, the equipment can be quickly dismantled and the pursuit of game can continue. The device allows you to fire from a moving vehicle, as well as hit fast-moving objects. On automatic weapons, it is usually mounted on the side of the receiver. Red dot sights are very sensitive to low temperatures. In severe frost, the battery may fail and the entire device will fail.

Real Japanese quality

One of the most common are Hakko BED red dot sights. They are produced by the Japanese company Tokyo Scope Co., LTD. This means a lot considering that almost all products are manufactured in China. Brands from almost all industries have their production facilities in the Middle Kingdom. Hakko red dot sights are assembled down to the last screw in Japan. The products are distinguished by high optical characteristics and structural strength. Available in both closed and open versions. Both provide a choice of one of four labels. In closed devices, 11 levels of illumination can be used.

Owners who use these devices confirm that the devices are indeed waterproof and shockproof, and the gas filling of the internal space prevents fogging. The Hakko collimator sight is highly reliable and can withstand the recoil of 12-gauge shotguns. The device requires installation on a Weaver mounting base. Although any Hakko BED collimator sight is not critical to the distance from the shooter’s eye: the most acceptable pupil distance from the exit screen is at least 100 mm.

The Ultimate Holographic Sight

Many experts and professional shooters recognize the American holographic collimator sight EOTech as the best example. This is a direct descendant of a military product. The difference between these open-type devices and their counterparts is that they have a laser optical device (the mark is recorded in the form of a hologram and illuminated by a laser), which provides considerable advantages. Firstly, the brightness of the mark can be adjusted over a wide range - the variator offers 21 levels. This makes it possible to fire in any weather conditions. Some samples are equipped with thermal imaging and night vision functions. And secondly, the EOTech reflex sight has practically no. This was achieved thanks to a complex brand projection system. It is visible even in rain, snow and heavy pollution. The device remains operational in case of mechanical damage.

Long operating time is achieved through automatic shutdown. The device can be programmed for 4 or 8 hours. An important advantage is the small size and curb weight. The device is very convenient when used on 12-gauge shotguns. Many devices use standard batteries: AA batteries. Batteries can be found in any store. Their replacement occurs through simple manipulation and takes no more than a minute. When changing batteries, zeroing the red dot sight is not required. Overseas products are very expensive. Top models cost over 60 thousand rubles.

Another American product

The Sightmark red dot sight is significantly cheaper, but that doesn't mean it's low quality. Sightmark is a subsidiary of Yukon Holding, which produces products for law enforcement and the Department of Defense. The products are mostly open-type, have up to 7 levels of brightness adjustment and are designed for installation on smooth-bore weapons up to 12 gauge. Dovetail type mounting device, strip has a width of 11 mm. Some samples are mounted on a Weaver/Picatini base. The sights are lightweight and highly reliable. A significant part of the products is produced in China.

Domestic is no worse

In 2009, the Cobra collimator sight appeared on the market in the EKP-8-21 version. This is the first and so far the only digital optical device for civilian use. The open type device is intended primarily for installation on semi-automatic weapons of the Bekas series. The Russian sight is mounted on a dovetail mount. The electronic circuit allows you to select four types of marks, 16 brightness options, and also remember information about the type of mark and the brightness of the glow. The maximum range of ballistic corrections is up to 600 meters. The Cobra collimator sight is highly reliable. Owners note that after several dozen shots, the settings are saved and the seat is not deformed. Moreover, aiming in low light conditions improves over time. Some owners complain that the device has significant weight and height. The device can be used with the rail of MP-251, IZH-18, IZH-27, IZH-94, and “Taiga” shotguns. You can aim with one or two eyes.

How to mount?

An important issue that overshadows the choice of the device itself is the method of attachment to the weapon. Most types of smoothbore weapons do not provide any standard devices or consoles for installing additional devices. The exceptions are domestic “Saiga”, “Bekas”, pump-action shotguns and some models intended for self-defense. The hunter should look for a technical solution on his own. The choice is limited: dovetail and bases (also called slats) Weaver and Picatini. The mounting of the collimator sight in the vast majority of samples involves placement on Weaver rails using integrated seats. Only sights equipped with special mounting rings can be mounted on a dovetail device. Some models attach directly to the rifle's sight rail. As a rule, such electronic optics have small dimensions and weight. These include the well-known Docter compact sights. The light mark of this device is clearly visible both in the snow and even against the sky. However, their cost may exceed the price of the weapon itself.

Not very reliable

Domestic craftsmen install a seat under Weaver and on a dovetail. For this purpose, special adapters are made. When choosing transition devices, each sample requires an individual approach. Thus, the Vologda Optical-Mechanical Plant produces a product of the same name (VOMZ). The steel console is designed to accommodate an additional sighting device of any type of mount. But, for example, a 16-gauge rifle can only be placed on a ventilated rear sight up to 7 mm wide. This design leads to significant weighting of the weapon and disruption of its alignment. The weight of the adapter alone is more than 100 grams. According to user reviews, such a mount is not durable and begins to loosen after a dozen shots. Alternatively, install an optical device that is not too heavy. Based on this, the same collimator sight on the IZH-27 should weigh no more than 90 grams. What can we say about more powerful weapons and the corresponding technical means?

An expensive stone needs a worthy setting

If you purchase an expensive optical device, there is no point in saving money on its installation. The bar and bolted connections must have a sufficient margin of strength to not only fix the relatively heavy sighting device, but also withstand recoil loads over a long period of operation. A 12-gauge red dot sight must be mounted only using specially designed standard mounting devices. A wide variety of dovetail and Weaver/Picatini trims are available for sale and in online stores.

It is necessary to select a product that follows the contour of the receiver. Also, the thickness of the body of the box itself should allow drilling a hole and cutting at least three turns of thread. It is best to cut threads using professional equipment. You should also take into account the distance from the eye at which the collimator sight will be located. Reviews from experienced owners indicate the need for additional sealant treatment of the threads and the surface of the junction of the console itself and the plane of the receiver. All other installation methods are money thrown away.

Optical zeroing

Like any other optical device, after mounting on a gun, the scope requires zeroing. The shooter must have a clear idea of ​​where the bullet or shot will hit at a distance of 35-50 meters. Most devices are equipped with regulators. In this case, fine tuning is carried out by adjusting in two planes using two rotating drum regulators. For a certain distance, you should remember the position of the controls. Many people believe that the so-called cold shooting is enough. In this case, ammunition with a red dot sight is used. Zeroing in a red dot sight may not give the desired result. This is due to the fact that sometimes in hunting weapons there is a mismatch between the axes of the barrel and the chamber. Cold alignment can turn into zeroing the chamber. It is necessary to take into account the correction when shooting handheld, as well as noticeable recoil, since a 12-gauge red dot sight is most often mounted.

Another way to adjust the optics is by fixing the barrel in a special machine or vice. The barrel is aimed at a fixed point, and after that the sight is adjusted. Cold zeroing can be replaced by a procedure of several dozen test shots. Any optics requires painstaking adjustment, including a red dot sight. Reviews that experts post on thematic forums often contain advice to fire several series of four single shots. Based on the results of hits on the target of a particular series, the average point of impact and its deviation from the center of the target are recorded. The sight is adjusted and after that - the next series of shots. And so on until a satisfactory result is obtained.

When shooting bullets, adjustment is carried out using the same type of cartridges and at the same distance that will be used in real conditions. However, in practice this is not possible. It is best to zero the device for use at several likely firing distances, and record the results of hits on the object with notes in a notebook. At the same time, corrections of angular indicators proportional to the firing distance are recorded.

– This is a separate class of optical sights for installation on military, hunting and sporting weapons. The collimators have a magnification of x1, which eliminates distortion of target sizes, and an unlimited field of view. Even with active movement of the eye relative to the center of the sight, due to the rapid alignment of the luminous mark with the target, the aiming speed is several times higher than with other devices. The luminous reticle is clearly visible both during the day and in relatively low light, and with several interchangeable reticles, you can change them depending on specific conditions. Some models are combined with a laser target designator for targeted shooting from any position.

A red dot sight is considered the best choice for shooting at short distances (100-150 m) at moving targets of medium and large sizes. These red dot sights can be installed on different types of firearms, but they are most popular among air rifle enthusiasts. Along with this, collimators are great for pistols, bows and crossbows. These sights usually have built-in mounting brackets, so when purchasing, you need to make sure that the device is compatible with the weapon you are using.

TYPES OF COLLIMATOR SIGHTS:

Active and passive. The first type of sights operates on batteries, so their reticle is always visible. In passive sights, the mark glows only when there is sufficient ambient light.

Open. The simplest in design and affordable sights, designed for standard shooting conditions. Open sights are also called single-lens sights because they only have a front lens in a frame. Due to the fact that these devices are less well protected from precipitation, it is not advisable to use them during rain and snow, since drops can fall on the glass and distort the brand. At the same time, unlike closed sights, open sights are much lighter and more compact, therefore they do not block the view with their body and allow you to aim with both eyes. Their advantages include a clear, unobscured field of view. Open sights are the most optimal solution for small-caliber carbines.

Closed. Models in this category are a shortened version of an optical sight, where the optics are located in the spotting scope. Closed sights, in addition to the front lens, also have an eyepiece lens. They are better protected from external factors, therefore they are all-weather devices, but they are characterized by shading of the aiming area. Closed red dot sights are larger in size, but due to their durable housing they can withstand greater recoil. If you install a special optical attachment, you can double the magnification of the sight and, accordingly, its range. Fixed sights are usually mounted on long guns of medium and large calibers.

Holographic. Devices of this class are of the open type, so they do not block the view and allow you to aim with both eyes. The main feature of holographic sights is the presence of a flat hologram with an aiming mark, which is visualized by a laser beam. Both standard and 3D reticles are applied to this transparent hologram. They are perfectly visible in any lighting and are always located in the center, regardless of what angle the shooter is looking at. Holographic sights, like closed-type models, have proven themselves to be excellent when used with shotguns. Their cost is higher than other types of collimators, since the process of producing a hologram is complex and expensive.

FEATURES OF COLLIMATOR SIGHTS:

It is believed that collimators increase the weight of the weapon, although even when using closed sights the weight is not so significant. In addition, the installation of any optical sighting devices, one way or another, affects the total weight of the weapon, but this does not mean that this deteriorates its balance. Red dot sights (especially open sights) get dirty quickly, but regular cleaning or protective caps on the lens and eyepiece will reduce the likelihood of dirt getting in. There is an opinion that at low temperatures the battery life of active collimators powered by alkaline batteries is reduced to a minimum. However, as practice shows, even with a decrease in capacity at subzero temperatures, alkaline batteries can provide several hours of full operation of the sight. Along with this, you can always have a spare set or use lithium cells that are less sensitive to cold.

Smoothbore weapons are preferred by both beginners and experienced hunters. Most shotguns are relatively inexpensive, easy to use, and have a wide variety of cartridges on the market. And, of course, they are suitable for almost all types of hunting (not to mention self-defense). Therefore, such guns are most common among hunters, and the most popular is the 12-gauge due to its greatest lethality. And, despite the fact that in this article we will primarily talk about the collimator for the 12-gauge, everything said for it is also true for calibers of lower power: 16-gauge, 20-gauge and Lancaster calibers (.366 and 9, 6/53), adjusted for recoil energy.

Regardless of the type of striking elements (shots, buckshot or bullets), the main differences between 12-gauge smoothbore weapons and other types of firearms are:

• The most powerful muzzle energy(up to 4,500 J for Magnum cartridge);
• Shortest sighting distance(usually no more than 100 meters for a bullet).

Both of these parameters, due to the simplicity and reliability of the optical design, are satisfied by most collimator sights. And since smooth-bore firearms are the most common among hunters and shooting enthusiasts, which red dot sight to install on a 12-gauge gun is one of the most common questions that our specialists have to answer. In this article, we have collected all the experience in operating red dot sights, collected based on the results of numerous reviews from our customers, mainly hunters.

We have grouped the catalog of collimator sights for smooth-bore weapons by type of mounting on the weapon: using the links below you can go straight to choosing a sight.

If it is difficult for you to choose from a variety of models, below in this article is presented, which is based on hunter reviews, the number of sales and the number of complaints (or more precisely, the complete absence of returns for these models). Still, we strongly recommend that you read the article below.

Impact limit

In case you don’t read to the end of the article, we will make the main warning at the very beginning:

Important! Muzzle energy of 12 gauge - 4200 J, 12 Magnum - 4500 J. Basic collimators can withstand 3800 J.

Accordingly, the recoil of the weapon causes a colossal shock load on the sight and bracket. When choosing a sight, first of all pay attention to the muzzle energy of the cartridge, correlate it with the weight of the weapon and the characteristics of the sight, which are indicated in its passport. Despite the relatively low cost of smoothbore shotguns, you need to take the choice of a sight based on impact load seriously: most cheap scope models are not suitable for smoothbore guns. And you definitely shouldn’t order unknown brands (or fakes of famous ones) from China.

At this point, you should separately warn about the dangers of ordering scopes directly from China and the counterfeit products that have flooded the market. Each domestically produced sight is tapped on a stand (like) to eliminate defects. Chinese manufacturers save on technological processes and, if they do not control the technological chain, skip the stage of mechanical tests. By ordering from China at your own peril and risk, you lose the opportunity to return the scope, as well as warranty support. This also applies to counterfeit products - here we can give only one recommendation:

Pay attention to the price (famous brands cannot cost a couple of thousand rubles) and information about the seller: companies that have been operating in the optical market in Russia for a long time care about their reputation.

What is the unreliability of such sights? For example, with a collimator sight, a fairly simple optical device, after several shots the aiming mark deviates from the axis of the shot. Hunters have repeatedly approached us with requests to repair such sights, which, of course, is impossible. In the saddest case, the scopes completely “scatter” - they literally lose the lenses...

In most cases, installing an optical sight on a smooth-bore weapon is pointless (there are special cases when 12-gauge optics would be justified). This is due to several factors. First of all, this is a short firing distance from smooth-bore guns - at such distances everything can be seen quite well, without the magnification that standard optics provide. In addition, when shooting from a shotgun, “catching a target,” especially a fast-moving one, will be much easier with full vision, that is, with two eyes, which is impossible when using optics. And the last thing is the weight of the optical sight, which upsets the balance of the weapon (often very light). As a result, the optimal choice for a smoothbore gun is a red dot sight, which is used when shooting at short distances, allows you to aim without covering your other eye, and is usually lightweight.

The influence of the design of 12-gauge weapons, striking elements and type of hunting on the choice of a collimator sight

The collimator sight is better suited than other types of sights for smooth-bore weapons and in particular 12-gauge weapons at all target firing distances:

• 30 meters for self-defense,
• 50 meters for hunting with shot and buckshot,
• 100 meters for hunting with a bullet.

And although the distance range indicated above is approximate, it is primarily influenced by the design of the weapon and the type of striking elements. Weapons and striking elements are selected according to the type of hunting and type of game. And yet, more often than not, a 12-gauge smooth-bore gun is used mainly for hunting summer game (goose, duck) or large animals (elk, wild boar). These are fast moving targets and the speed of aiming at the target largely depends on the viewing angle of the sight. And the viewing angle is better with an open collimator sight...

Open or closed

Regarding the belief of many hunters regarding an open collimator sight that such a sight gets clogged more often than a closed collimator, we briefly note that this is true, for example, during a snowfall. Of course, snowfall or heavy rain are not the best weather conditions for hunting.

You should make a choice in favor of an open sight in case of hunting “offhand”, moving targets or in self-defense; in favor of a closed sight - if the animal does not see you and there is time to take aim: stealthily, in ambush or when hunting with a bullet at a large animal. Additionally, a closed sight has less parallax, making it “more accurate,” which is important when hunting at long range (with a bullet).

The advantage of self-loading smoothbore carbines is their rate of fire. To enhance this advantage, it is necessary to quickly compensate for the weapon’s deviation from the target with the powerful recoil of the 12-gauge. And here again the wide-angle open collimator wins.

Without straying too far from the characteristics of collimator sights, in order to understand which ones are better, let’s figure out what other types of collimator sights exist and what criteria should be used to choose one. On our website we talk about the characteristics of red dot sights; here we will consider only factors that are significant for 12-gauge.

Kinds

Collimators are a class of sights that include several types that are perfect for smoothbore guns. They are united by a number of undeniable advantages, which are as follows:

1. Fast and easy aiming. Unlike an open sight, with a collimator, the mark combines both the rear sight and the front sight. Thanks to this, aiming becomes easier and faster, as it is easier for the eye to focus.
2. Prevents distortion of target dimensions. Unlike an optical collimator, the collimator does not magnify the image; you can aim with both eyes.
3. Provides a wide field of view. This is especially important for hunting offhand and fast-moving targets, such as birds.
4. Much easier compared to other types. When hunting from the approach, when you have to track an animal, this is especially important. Also pay attention to the weight of the bracket.

Thus, a hunting collimator sight for a smoothbore shotgun of this type is the optimal choice for almost any hunt. It is perfect for a hunting rifle. Such devices are divided into several types:

1. By type of energy consumption:

with built-in batteries. Unlike optical ones, almost all modern collimator devices belong to this type. Their special feature is that they operate on batteries, so their aiming mark is constantly on.

1. By type of housing:

Open. They have compact dimensions and light weight. Their advantages also include a wide viewing angle.	An open type option is the Pilad 1x30 Weaver. Completely covered with a protective cap.
Closed. Equipped with a protective housing and lenses. They have somewhat larger dimensions, but are more unpretentious to weather and operating conditions.	Closed type option - Pilad 1x20 Avis

1. By type of mark projection:

• collimator The design of the tag is carried out on the face, which is located on the front of the device. Externally, the mark can be in the form of a dot, a dot in a circle, a square, or crossed lines;
• holographic. This collimator sight is of the open type and is suitable for smooth-bore weapons. The peculiarity of this type lies in the hologram on which the aiming mark is located, visualized by a laser beam. Conventional and three-dimensional reticles are applied to it. They are always clearly visible, regardless of the light level, and they are always in the center, even if the hunter looks from different angles. Compared to other types of collimators, holographic ones are more expensive;
• dioptric ( for sport shooting, not used for hunting). Thanks to the large sighting line, this type provides maximum shot accuracy. In addition, diopter sights guarantee high aiming speed, since the process of combining the front sight and the aperture-hole is greatly simplified.

1. By type of fastening

Most red dot sights already have a monolithic bracket with the body. Such a mount greatly reduces the overall cost of the sighting device, especially when the gun is already equipped with a corresponding rail. For your convenience, we have grouped red dot sights by type of attachment to the weapon:

There are usually no issues with installing a red dot sight on a smoothbore shotgun under Weaver - here you just need to pay attention to the length of the rail on the weapon (or the adapter bar), so that it is not shorter than the length of the sight. But for the dovetail and ventilated strip - be sure to measure the width of the strip before ordering! They are different even within the same model ().

1. In terms of internal functionality:

• with the presence of laser target designators (laser designators) - which can be convenient for self-defense at close range or shooting a bullet at medium range, without changing the sight to an optical one or a magnifying attachment;
• with replaceable aiming marks. This option allows you to adapt to the time of day (for example, at dusk), the type of terrain (dense forest or open field) and the type of game;
• with magnification or magnifying attachments (tactical).

How to choose

1. Muzzle energy and recoil resistance. This parameter is always indicated in the scope's specifications.
2. Optical design of the sight. Open sight - wider viewing angle, which will be an advantage at short distances, for shooting at moving targets. Closed - better protected and has less paralysis.
3. Changing the brightness of the aiming mark - the maximum brightness will “illuminate” the target.
4. Sight weight.

Additional technical issues and questions can be clarified by contacting sales consultants in the store when choosing a model.

Rating of red dot sights

To simplify the selection process, below is a brief overview of the models and the best collimator sights with optimal characteristics for smooth-bore weapons:

1. Pilad P1x42 Weaver sight from the manufacturer VOMZ.

Pilad P1x42

This option is rightfully considered one of the best. Features include the ability to withstand any caliber. Pilad P1x42 Weaver is an affordable open collimator. A distinctive feature of this particular model is that it provides the hunter with a wide field of view - 180 degrees, which creates the necessary conditions for accurate shooting at moving targets or shooting at the top. The aiming reticle is available in three types, the reticle is illuminated in three options, and its brightness can also be adjusted. Excellent characteristics and low weight (0.15 kg) make the Pilad P1x42 Weaver the optimal option for various types of weapons. Models for dovetail mounting and ventilated strip are also available.

1. American scope for 12 gauge Rubicon, 3 MOA - Weaver.

Rubicon Weaver

An open-type model with compact dimensions and a lot of advantages: a wide field of view, clear image transmission without distortion, a durable aluminum body, manual switching on and adjustment of the brightness of the mark, a simple installation and adjustment process. A reliable choice for mounting on a 12 gauge shotgun. The 3 MOA reticle is perfect for shooting both large game bullets (such as wild boar) and bird shot. The manufacturer Bering Optics has a similar model with automatic switching on and auto-adjustment of the brightness of a larger 5 MOA mark, which is more suitable for birds - OP-LA Reflex.

1. Compact closed-type collimator Hakko BED-70 weaver.

Hakko BED-70

Hakko BED-70 is a universal compact model of a closed-type collimator sight. Can be installed on any Weaver based weapon. The 4 MOA reticle is best suited for medium to large game at 200 meters and closer. The advantages include the presence of 11 gradations of brightness, the absence of parallax up to 100 meters, light weight - only 100 g, and a simple battery replacement process. The sight does not allow water to pass through and is waterproof. Traditionally for Japanese Hakko sights, the sight has a lifetime warranty.

1. Collimator.

PKU-2 is a closed-type sight and closes the rating of red dot sights. Of the models presented in the rating, PKU-2 is cheaper than its Japanese (Hakko) and American (Aimpoint) counterparts, but is not inferior to them in terms of characteristics: resistance to any caliber, high resistance to damage. Compact and lightweight - its weight is only 0.14 kg, the sight is practically not felt on the gun, making its use especially convenient. It has an extremely durable body - made of aircraft-grade aluminum. There is a possibility of adjusting brightness - 12 gradations. The model is suitable for use in the most extreme conditions, as the temperature ranges from -40 to +50 °C. Separately, it should be noted that the sight is mounted on a Weaver sighting rail. PKU-2 is a worthy choice for smoothbore weapons.​

Other types of sights for shotguns

Most likely, you no longer have doubts about the type of sight. And, despite the fact that the red dot sight is indeed better than other types for all firing ranges from 12-gauge smoothbore weapons, for special cases other types of sights can be used, for example:

• laser or a combination of laser + collimator - for self-defense (at short distances, indoors);
• optical - for people with low vision, sports or amateur target shooting;
• night vision - obviously for use in the dark.

Which red dot sight to choose for a 12 gauge smoothbore weapon? Fans of 12-gauge smoothbore rifles sooner or later face the choice of a high-quality and reliable sight.

There is no point in installing a large and bulky optical sight on a smoothbore and is useless for several reasons.

Firstly, the firing range of a hunting rifle is small; a fast-moving target is clearly visible through conventional optics, and even better with the naked eye.

And the second point is mass; with its weight it introduces an imbalance into the weapon. Therefore, the choice of amateurs and professionals stops at collimator cameras.

It is light in weight, ideal for short-range targets and quite easy to use, unlike a mechanical one.

It is important to know: basic collimator models can withstand 3800 J, with a Magnum muzzle power of 4500 J and a 12 gauge smoothbore weapon 4200 J.

Advantages

The main advantages include:

1. Aim speed. Compared to an open shot, where three marks need to be aligned for an accurate shot, in collimators the rear sight and front sight are already aligned, so the time spent sighting is reduced and it is easier for the eyes to focus.
2. Error in distortion. The lenses on red dot sights are simply concave to reflect light, so distortion is minimal. Almost all models on the market do not have an enlargement effect.
3. Wide view. When aiming, there is no need to cover your other eye, which is undoubtedly very convenient.
4. Thanks to its low weight it is very convenient to use.

Kinds

All collimators can be divided according to the following indicators:

• on energy consumption;
• by type of body;
• by projection;
• by type of fastening on the bar;
• by functionality.

Now let's look at each classification in more detail.

By energy consumption

The most common type of device runs on batteries. Many have the ability to remove the battery without removing the sight itself, without losing the target, which is very convenient.

Self-powered devices are much higher in price and are not intended for hunting, but rather for the army. They have a built-in battery with a large reserve for several years of use. Many devices are designed for use in difficult climatic conditions.

From the type of case

Closed models are installed on large and medium calibers and have several lenses.

They look like a shortened version of standard optics and work in any weather.

They are good in their own way, but they are quite bulky and weigh more than their open counterparts.

Open collimator type. In everyday life they are called “single-lens” due to the number of built-in optical elements.

The size allows you not to cover the sight with the body, and they are light in weight. A very common type of device due to its budget and functionality.

By projection

1. Dioptric. Thanks to the simplified alignment of the front sight and aperture, the holes have an increased aiming speed. A large aiming line guarantees shot accuracy.
2. Holographic. Used in open type. It is characterized by the presence of a hologram with an applied targeting reticle, which is visualized by a laser beam. Reticles are always visible and independent of lighting. They have a high price segment.
3. Collimator. The simplest type of device and reliable in its own way.

By type of fastening on the bar

According to the method of mounting on the bar, collimators are:

• Weaver;
• "Dovetail";
• ventilated strip.

By functionality

By functional purpose they are distinguished:

• tactical (with magnification);
• with the ability to change aiming marks;
• 3With the presence of laser pointers.

Expert advice: powerful recoil also plays an important role in the life of the collimator. Based on this, you should approach the purchase of a scope more consciously so that the chosen model will serve for a long time.

Any type of red dot sight is suitable for a smoothbore; good optics do not necessarily cost a lot of money.

The market for optical sights is represented in a wide range.

Among the reputable brands you can find inexpensive models of Russian or Chinese production, inexpensive models of Russian or Chinese production that will show themselves worthy in “battle”. Basically, sights are produced with a bracket for mounting on an aiming bar. Watch an overview video about the HAKKO BED5 collimator on the IZH-27 and IZH-58 shotguns:

The purpose of using any firearm since its invention was to quickly and accurately hit the target with a bullet. All developments and improvements in weaponry over several centuries are aimed at increasing the speed of aiming at the target and the accuracy of the shot. So, at one time, an ordinary front sight appeared, with the development of a science called “optics” - optical sights, and with the development of electronic technologies - collimators.

Features of the red dot sight

The fundamental technical difference between this model and other types of sighting devices is that it does not have a permanent front sight or reticle. Aiming is based on directing a beam of light into the shooter's eye using a lens, which is compared with the target and gives very accurate guidance to the target.

With a slight deviation of the weapon along the horizontal or vertical axis, the mark also moves, still indicating the direction of flight of the bullet. Such qualities are unimaginable for other types of sighting devices.

Principle of operation

The design of a collimator sight involves the use of simple electronics and optical effects. The light source is directed into a reflector lens, which generates a stream of light in the direction of the shooter. A person holding a weapon in a firing position sees this flow in the form of a point, which moves along the lens depending on the displacement of the axis of the weapon relative to the shooter’s axis of view and makes it possible to quickly and accurately point the weapon at the target to fire a shot.

The collimator takes advantage of human binocular vision, giving the shooter the ability to aim without covering the other eye.

Difference from other types of sights

When using a standard open front sight, the shooter must align his gaze, the front sight on the nose of the barrel and the rear sight on its near edge on one axis before firing. Only when these conditions are met can the person firing the shot be sure that the bullet from the barrel will fly in the right direction. This method reduces mobility during shooting and visibility, since the shooter needs to close the second eye so that binocular vision does not interfere with accurate targeting.

When using an optical sight, shooting while moving is almost impossible due to strong vibrations of the mark. High shooting accuracy in this case is achieved by a stable position of the weapon, in which it is possible to point the crosshairs at the target. For such measured shooting, only conditions of large distances between the shooter and the target are permissible - the conditions of sniper shooting.

This device allows for accurate shooting at close and medium distances. All that is required is to combine the direction of view and the light flow, after which the shooter sees where the bullet will hit. Compared to a conventional open sight, a red dot sight, whose operating principle allows you to spend a shorter period of time on aiming, gives more space for accurate shooting while moving.

In conditions of long-distance shooting, the collimator does not allow accurate shooting, since the marker can cover almost the entire target, so it does not compete with sniper optical devices.

An important difference between a collimator and other devices is the use of electricity for operation. Without power, the light source will stop working, making accurate aiming impossible. Therefore, when using a device of this type, you should remember that it works until the battery runs out.

Application

Since their appearance, red dot sights have spread to many areas of human activity related to weapons. Besides military and police units around the world, they are most common among hunters and airsoft players. In some cases, the collimator is even placed on the bow.

This device is suitable for almost any type of small arms intended for close and medium ranges, including heavy shotguns and even machine guns. So what is a red dot sight for? Shooting in combat conditions or regular hunting with a collimator sight will definitely become easier and more convenient after you get used to it.

Types of collimators

Collimators are divided into open and closed. Initially, these classes meant two types of collimator sights, significantly different in their structure.

Closed devices in the classical sense were those that did not have a transparent lens. Through it, the shooter did not see the space behind the sight with the eye that sees the front sight.

Aiming was achieved by the need to use two eyes at once, one of which sees the space ahead, and a mark is projected onto the second by a collimator. Thanks to binocular vision, the human brain in this case compares different images from two eyes and the shooter sees the front sight in front of the target and can take aim.

Open was a model with a transparent lens and an open front wall. Through such a sight the target is visible. Therefore, shooting with a collimator sight using only one eye is possible only with an open type.

With the development of collimators, the need for closed sights in the classical sense has disappeared. There is a new understanding of the difference between closed and open devices. Nowadays, an open sight is a sight in which the lens is fixed in a small frame and does not have an auxiliary protective structure around it.

A closed device is a device in which the focusing lens is located in a sealed structure consisting of a massive frame and an additional front lens. This design protects the focusing lens from raindrops, dirt and other foreign objects that can spoil the quality of aiming. It is precisely this understanding of the concepts of closedness and openness that is widespread at the present time.

Operation, care, storage rules

To ensure that a high-quality collimator does not fail during shooting, you need to install it only on weapons with the appropriate caliber. The device, intended for pistols and light semi-automatic weapons, cannot be installed on weapons with high recoil, as this can quickly disable it.

It is quite easy to damage this device. The lenses do not withstand any physical impact well; they are easily scratched, which reduces the quality of aiming. It is better to wipe them from dust using special napkins and without using improvised means, as some fabrics can leave scratches.

Batteries are inserted into the device only before shooting and removed after shooting. When storing weapons, batteries must be kept separate to protect the electronic parts of the device from possible damage if the batteries fail.

It is also advisable to remove the device while transporting the weapon, or use special cases that protect it from possible physical impact.

How to choose?

When choosing, first of all you should know what caliber weapon it will be installed on.

When choosing from models designed for weapons of a suitable caliber, you need to understand that cheap options are not complete and reliable, and will go astray during shooting and sudden shaking. A stable and reliable design can only be expected from well-known and time-tested manufacturers, so you cannot save money here. A cheap device will quickly break down during active use and you will still have to purchase a new one, therefore, it is better to immediately buy a more expensive but reliable one.

The choice between an open and closed device is based on the conditions in which it will be used. For mobile shooting at close distances, where there may be an unexpected physical impact on the device, impacts, or pieces of earth falling into it, it is better to purchase a device of a strong, closed design.

For installation on rifles intended for long-range shooting, you can choose an open collimator suitable for such weapons, but a closed one is also suitable, since the viewing angle in this case does not play an important role.

Sniping is not possible with a standard device, but there are options with lenses that provide some proximity for more convenient long-range shooting.

Shooting Features

After purchasing the device, you need to shoot it. First, you need to study the theoretical part, understand how the collimator sight works and how to correct its aiming at the target, and then zeroing the collimator will not cause any problems.

Installation and configuration

High-quality branded devices are provided complete with mounts for two mechanisms - dovetail and Picatinny rail. Small arms are also manufactured with appropriate mounts on the body, therefore, installing the device on the barrel consists only of firmly fixing it in the right place by tightly tightening the clamping screws. They need to be tightened tightly, but moderately, so as not to break the thread.

Before shooting a red dot sight, you need to carry out its initial setup. Setting up is not particularly difficult; any hunter can figure out how to set up a red dot sight. In expensive models, you can adjust not only the brightness, but also the shape of the front sight. Most often, the choice is between a dot, a cross, a circle with a dot, and a cross with a dot. Brightness is adjusted depending on the lighting.

In the dark, you should lower the brightness level of the light flux so as not to illuminate the target.

At the same time, there is no need to be afraid that the point in the sight will be seen by the enemy located on the other side of the weapon, because the visible beam of light is very weak and is reflected in the direction of the shooter’s eye. Thanks to this device, the front sight is visible only to the person looking through the sight, and to no one else.

Selecting a position and distance

To shoot a weapon with any scope, you need to ensure a calm atmosphere in the place where the shooting will take place. Ideally, there should be no wind or precipitation, and there should be no places with changes in humidity, such as flowing rivers, near the bullet’s flight path. Zeroing a collimator sight begins with shooting at targets located at close range. With each adjustment step, the distance to the target can be increased.

Target selection

For zeroing weapons with a collimator, targets are selected depending on the type of weapon. For the first stages of zeroing, it is preferable to choose large targets, since the error before zeroing can be very high. When using firearms, dense targets for shooting live ammunition are suitable, and when shooting from pneumatic weapons, thin targets for pneumatics are sufficient.

The shooting process step by step

Zeroing occurs in several simple sequential stages.

1. Before zeroing the collimator, you need to place the weapon in a stable position so that the swinging of the shooter’s hands has as little effect as possible on the shooting accuracy. You can use a stop in a stand, or fix the weapon very tightly in a vice with soft linings.
2. The weapon is aimed at a target located 10 meters from the shooter.
3. Fire 3 shots.
4. Based on the shooting results, a deviation of the bullet trajectory from the aiming point is observed. Using the appropriate screws, the collimator sight is adjusted and the position of the marker is adjusted.
5. Fire 3 more shots.
6. If the shooting results are acceptable, then the target is moved to a distance of 30 meters.
7. Shooting is repeated and adjustments are made in accordance with the shooting results.
8. When the accuracy of shooting at a target at a distance of 30 meters becomes satisfactory, then the target can be moved to a distance of 100 meters.
9. The process of sighting and adjustment is repeated again until satisfactory accuracy is obtained.

When shooting at close and long distances becomes sufficiently accurate, zeroing the red dot sight is completed.

Cold shooting

In addition to the usual shooting method, there is also the so-called cold shooting. It happens without a single shot being fired. To do this, a special tube with a laser is inserted into the barrel of the weapon, which is directed exactly along its axis.

As a result of using such a device, a laser marker appears that points exactly to the point at which the barrel of the weapon is pointing. This is the point of impact of the bullet without taking into account the decrease in its trajectory during flight.

After installing the guiding laser, the position of the marker is adjusted to the laser marker, taking into account the lowering of the bullet trajectory. After this, the device can be considered zeroed, but for reliability, you should still check the accuracy of the weapon with live ammunition after it has been cold zeroed.
