Laser cartridge Yukon Sight Mark 12GA Laser Bore Sights is an independent, ready-to-use product. Allows you to zero or check the zeroing of hunting weapons without firing cartridges. This is especially true when using expensive ammunition. You can fine-tune any sighting devices of your weapon during the “cold” zeroing stage. It is impossible not to note another useful function of these laser sighting cartridges - the ability, right before a hunt, to very quickly check whether your well-aimed optical sight has gone astray during transportation. Remember that misses are not uncommon for this reason. The light weight and shape of the cartridge are convenient to use and do not take up much space in the equipment of the shooter and hunter.
Specifications: Used for zeroing smoothbore shotguns 12 gauge (12 GA). Laser type: red semiconductor ( Visible Red Laser). Laser wavelength 632- 650 nm. Emitter power less than 5 mW. Operating modes ON / OFF (On / Off end cap). Shooting distance from 13.7 m (15 yards) before 183 m (200 yards). The maximum distance depends on lighting conditions. The optimal shooting distance from 13.7 m (15 yards) before 91.44 m (100 yards). Spot size at a distance 91.44 m (100 yds) approximately 50 mm (approx. 2"). The non-parallelism of the laser beam to the barrel axis is 0.0005 radians. Power supply: 2 batteries LR48/AG5 1.5V or 3 batteries LR41/AG3 1.5V ( 1 hour continuous operation). Chuck body material brass. Weight no more than 150 g. Operating temperature range from -10 before +50 deg C.
Applications of Laser Bore Sights:
The system is absolutely independent of the type of weapon and is “tied” only to the caliber. Standard shooting distance 22.9 meters (25 yards). Place a target at this distance for shooting. If necessary, secure the weapon in a sighting vise, place it on a bipod, or place it on a resting surface. Unscrew the bottom of the Laser Bore Sights counterclockwise.
Insert the batteries into the plastic container, observing the polarity.
Insert the red plastic container (insulator) into the laser module (cartridge) and screw the bottom clockwise without much effort. The laser beam will burn continuously.
Attention: Be careful when using the laser cartridge to avoid damaging your eyes. Attention: It is forbidden to look towards the beam, direct radiation into a person’s eye, or place foreign objects in the path of the laser beam that cause its mirror reflection. Attention: When installing batteries, observe the correct polarity. Insert the powered laser model into the chamber of a rifle or shotgun of the appropriate caliber (on bolt-action carbines, the bolt must be closed). Align the laser dot of the sighting cartridge with the center of the target. When zeroing at a distance of 25 meters, the aiming mark of the optical sight is aligned with the laser dot projected at the center of the target. The weapon is zeroed by aligning the aiming line with the axis of the barrel at a given distance. The position of the center of the light spot corresponds to the weapon's midpoint of impact (MIP), without taking into account the ballistics of the bullet's flight path. Align the aiming line of the open sighting device of the weapon or sighting devices installed on it: optical, collimator sights, laser designators, luminous front sights and rear sights with the center of the light spot of the laser cartridge. When the laser beam deviates from the center of the target by 30 or 50 mm or another greater value, use the windage and elevation adjustment drums on your scope to begin adjusting the reticle of your scope to the correct position. This is done by clicking on your crosshair. Zeroing is considered complete if the crosshair of the weapon's sighting device is aligned with the center of the laser emitter spot aimed at the object. Note: If, in the process of adjusting the sighting devices, you aim at the center of the laser dot, then the bullet will hit the same spot only at those distances where the trajectory decrease is 0, for example 100 m. Therefore, if you plan to use the weapon at a greater or shorter distance, it is necessary to take into account the change trajectories in accordance with ballistic tables for a given ammunition. Remove the laser cartridge from the chamber. By turning the bottom of the sleeve counterclockwise, turn off the laser, or remove the batteries from the Laser Bore Sights.
Instructions for use and storage:
Attention: Remove the batteries from the Laser Bore Sights when not in use for an extended period of time. Deteriorated batteries can destroy the device. The device requires careful and careful handling. According to the degree of radiation hazard, the device belongs to class 2 CH 5804-91. The Laser Bore laser sighting module must be stored in a clean room at a temperature of +5 to + 40 degrees C and a relative air humidity of no more than 60%. (At air temperatures below +25 degrees C, the relative humidity can be increased to 80%.) The air in the room should not contain impurities that cause corrosion of metals and deposits on the surfaces of optical instruments.

We warn buyers in advance!
Since on smooth-bore weapons, the chamber drilling varies in diameter, on different models of smooth-bore weapons, the cold laser zeroing cartridge may not fit tightly inside the chamber. Accordingly, this affects the accuracy of the device when shooting. The cartridge for cold laser zeroing installed in the chamber is not additionally calibrated. If the cartridge does not point accurately enough at the target, it must be rotated in the barrel until the point becomes parallel to the barrel.
For the most accurate zeroing of bullet cartridges, use high-precision devices for cold zeroing of Red-i smoothbore weapons - the appropriate caliber. They are equipped with special O-rings for installation in the chamber. And they have the highest possible accuracy for cold-zero laser cartridges.

Greetings, dear community!
I would like to buy myself such a laser cartridge. Maybe someone has already used these cartridges. I am interested in the efficiency and beam range. Please respond and leave a review.
Dragon 03-04-2016 12:01
Wasted money.
Frayman 03-04-2016 12:04
I have such.
When installing the target, you can roughly nail it in order to at least hit the target. But it is advisable to do this at night.
kyk 03-04-2016 12:32
Bullshit, it's better to buy cartridges
River 03-04-2016 19:04
There are expensive ones and there are cheap ones. The cheap ones usually don't work very well. They don't even get into the chamber. The same effect can be achieved by placing a piece of mirror on plasticine. A good PLP is expensive.
Decide, try. Then tell me.
Frayman 03-04-2016 19:51
I bought a cheap one from Aliexpress. I installed a new scope on the new rifle. I inserted the cartridge, shined the light at the neighboring house at night, and nailed the sight to the spot. At the shooting range I immediately started hitting the shield. The laser cartridge was no longer available. I think he saved me a dozen rounds.

No, it’s far from bullshit, that’s the truth -

In addition, it really helps to control the sight, it shows, of course, not exactly the STP, but somewhere around, I have one on the Tiger and have been using it for a long time, at 50 meters there is a 5-7 cm difference from the STP, a lost sight can be easily checked if you approach it wisely - zeroed you point the sight at the object, remember the difference in readings, everything else is used to check the sight. It generally makes life easier for night light owners and saves hundreds of rounds of ammunition.
The thing is, in a word, necessary, don’t listen to those who say bullshit, or those who say that they set up a point and shot a nickel. These are those who didn’t hold it in their hands but have an opinion.

And some specialists shoot (!) with a laser cartridge (!) at 200m (!) and then go on a responsible (!) expensive hunt (!) and miss (?) and wonder WHY (!!!) damn (!)
A laser cartridge is a brilliant solution to a non-existent problem and a scam of suckers.
chijevs 03-04-2016 21:01
the cartridge is nonsense - a multi-caliber set is better - if not bent

I also use an inexpensive one, I change attachments on carbines - a sight, a callimator, covers, crowns, for rough alignment of the first shot it will work fine, and without noise and dust

This cartridge is needed on semi-automatic weapons and weapons where it is not possible to make a rough alignment of the optics along the bore. The alignment needs to be done at 25-30 meters, because this corresponds to a near zero. You should not expect high accuracy, because when the device is rotated, the point describes a circle/ellipse on the target, but as they correctly said, it will help save time and ammunition when zeroing in sight cartridges. You are already guaranteed to hit the target and will know where and how much to turn the adjustment drums.
The second device is more universal in caliber, but there are cases when it cannot be inserted into the barrel without distortion and the first one will be preferable.
hunter143 03-04-2016 21:27
Thanks for the feedback. I think the cartridge in the top photo will be more accurate.

But you don’t really need to twist the cartridge. It must always be inserted into the chamber with one side up (bottom, side). Mark the side and one side up.
Further..., it is convenient when changing OP. You can roughly “shoot” even at home: hang an A4 sheet on the wall, draw a dot in the place of the LP bunny and the OP mark (crosshair) point. You rearrange the OP and compare these labels. Also saves money and time.
The thing is useful. I have both 7.62x39 and 22LR.
kyk 04-04-2016 12:41
Damn, guys, the chores are full of crap. The cartridge and other laser crap have nothing to do with STP. How often do you rearrange your sights? I have no problems, the night light/day light has a normal error for hunting, but I still have to burn one or three cartridges for my own peace of mind.

I don’t think that any accuracy of more than 5 cm is possible on a device of any price, and the problem is not in the laser cartridge itself, but in the fact that at least this cartridge is not blown across your chamber, plus the misalignment of the laser and the laser.

Rough zeroing saves already expensive cartridges. The task of the LP is to catch on to the target, and then you accurately shoot at the target.
Absolutely right, this thing is needed, just not to use it in the same way as they wrote above about 200 meters and responsible hunts.

In the quotation book!!! Think about what you wrote.

And it’s easier to make adjustments to the sight using the minute grid on the target - it will be more accurate than using a laser.
It is possible to roughly draw the sight onto A4 sheet without a laser.
And you can also go to the toilet in the pit on the street, count in columns without using a calculator, call on your home phone, well, why do we really need the benefits of civilization................. Why make it easier for yourself life then??? Everything needs to be done the old fashioned way, along the bore, to burn cartridges that cost comparable to 1 LP, well, what’s the point of all this, really... All that’s left is to stop using the roads, it’ll be a shorter route through the forest...
Laser cartridge "LBS" 12 gauge for cold zeroing of weapons. Allows you to rebuild optical devices from scratch or make sure that they have not gone astray after transportation. The product is made of brass and is not subject to corrosion. Weight including batteries is about 100 grams.
Why should you buy a 12 gauge LBS laser cartridge?
- Suitable for any weapon, regardless of manufacturer. The LBS laser cartridge is suitable for almost all weapons equipped with 12-gauge cartridges, regardless of the weapon manufacturer.
- Zeroing without wasting ammunition. The product saves ammunition, which is especially important for those who use expensive branded cartridges. Thanks to its design, it can be used even in areas not intended for shooting, because does not require firing.
- Compact and lightweight. You can take the laser cartridge with you on long trips - it takes up virtually no space.
- Easy to use. The laser cartridge uses 3 LR41 batteries to operate. The product does not have buttons on the body; it is turned on immediately after installing the batteries. This system is due to the fact that it eliminates accidental pressing - the beam burns continuously. One set of batteries is enough for approximately 1 hour of continuous operation of the product.
Principle of operation
- Unscrew the laser cartridge sleeve counterclockwise, which also serves as the battery compartment cover.
- Insert 3 batteries, observing the polarity (plus to the bottom of the socket).
- Screw the bottom of the cartridge until it stops and the laser emitter will turn on.
- Insert the round into the chamber and align the center of the target with the laser dot.
- Adjust the aiming device so that its mark coincides with the central part of the spot left by the emitter.

And its further installation is not the most difficult thing. It is extremely necessary to ensure the alignment of the axis of the barrel bore and the optical axis of the sight itself; in other words, it is necessary to make sure that both the barrel and the sight “look” at the same point on the target.
Where the sight is pointing is understandable, and the position of the aiming point itself can usually be adjusted with verniers on the sight itself, but at what point is the barrel pointed? This question cannot be answered so easily. Really, where? The answer will be given by a series of shots from a rigidly mounted weapon. But this is not a panacea, since the quality of the shots greatly depends on the quality of the ammunition itself. Even if the cartridges are from the same box and the gun is fixed motionless on the machine, the bullets will by no means hit the same point on the target. Leave the fantasy of 100% hits to the Robin Hood films. Only he could use an arrow to split his previous arrow that hit the target. In life, everything is completely different. Please note that I am talking about ordinary “mass-produced” firearms, and not about special sniper systems made individually, with micro-tolerances and for special ammunition!
In a word, when shooting a gun under a new sight, you will spend more than one box of ammunition hitting the target... and your pocket too. Needless to say, dismantling/installing the sight will most likely require re-shooting?
Large financial and time expenses can be avoided by purchasing the device, which is discussed below.
So, welcome!!! - Laser cartridge of cold zeroing!
The principle of operation is as simple as a moo - by placing the switched-on cartridge into the chamber, you see at which point on the target the axis of the barrel bore is directed. All that remains is to align the aiming point of your optics with the point from the laser beam emitted by the cold-shooting cartridge. All! No shots required. Work for a couple of minutes and 0 financial costs Once you buy such a cartridge of the required caliber and then use it for the rest of your life, buying batteries once every 10 years
So, I bought the item on eBay from the seller hossen-usa from China.
The cost of the lot is $13.88 with trackless free shipping.
I paid with Palka on 01/11/2012, the parcel arrived on 02/7/2012. Almost month. Quickly... h34r:
And now for some funny pictures
The parcel itself is a regular white pimply envelope:
Inside is a small package:
Delivery set: cold sighting cartridge, three LR44 coin-cell batteries and instructions in English.
The cartridge itself has the usual silhouette for a smoothbore cartridge. The caliber and polarity of the batteries are indicated on the side. The paintwork of the case is durable - it was not scratched on the walls of the chamber.
There is a recess with a laser on top:
The bottom of the cartridge is the battery compartment cover:
There is no power button on the cartridge body. This is logical, since the walls of the cartridge must fit tightly to the walls of the chamber. There is simply no room left for the button. The cartridge is turned off by partially unscrewing the bottom.
The cartridge sits tightly in the chamber, without any play. It is important!
This cartridge is used for cold sighting of twelve-gauge carbines. The brand of the weapon does not matter. If the sight of a weapon has become lost during transportation, or you have changed optics, and are still close to the object of hunting, you can correct the sight using a laser cartridge Red-i. It allows you to avoid firing unnecessary shots, producing unnecessary noise. The accuracy of zeroing with its help is ensured by high quality manufacturing and precise adjustment.
Parameters of the Red-i laser cartridge, caliber 12
- The cartridge is powered by 393 batteries, which is enough to operate for up to three hours.
- The semiconductor laser beam is emitted with a power of 4 mW and a wavelength of 650 nm.
- The cartridge has a brass body with 2 O-rings.
- The cartridge turns on immediately as soon as its bottom contacts the chamber body.
- It can be turned on by pressing on the bottom of the cartridge with a metal object.
- At a distance of one hundred meters, the spot on the target will have a diameter of 2.5 cm.
Only Red-i cartridges will allow you to accurately zero your weapon at home and check your sights while hunting without firing additional shots.
Even the ejectors do not throw this cartridge out of the chamber like spent cartridges, but smoothly remove it from the chamber.The device has a special device instead of a primer, which allows you to fire blank shots without damaging the cold-zero cartridge. The cartridge is turned on automatically when it enters the chamber of the weapon.
Characteristics of the Red-i 12red laser cartridge
- Laser type: red semiconductor.
- Laser wavelength: 650 nm.
- Emitter power: 4 mW.
- Spot size at a distance of 100 m: approximately 26 mm.
- Power supply: 2 or 3 batteries type 393 (3 hours of continuous operation).
- Chuck body material: brass.
Since on smooth-bore weapons, the chamber drilling varies in diameter, on different models of smooth-bore weapons, the cold laser zeroing cartridge may not fit tightly inside the chamber. The cartridge does not depend on the type of weapon and is “tied” only to the caliber.
