MTs-21 is a single-barreled hunting rifle designed for commercial and amateur hunting. Many people use the MC gun for hunting. There are a large number of negative opinions about MC 21-12. Reviews sometimes talk about the unreliability of such a device, but it still has its fans. Model 21-12 is the first domestic semiautomatic device. These are single-barrel shotguns, the automation of which uses energy for recoil. This is what distinguishes it from other semi-automatic shotguns, which, in principle, have inertia, as well as the removal of powder gas.
The first release of the gun took place in 1958, but the constructively obtained model was not something new - rather, the gun was made on the basis of the Browning Auto-5. Of course, during the construction of the model has undergone very large changes, both inside and outside. For several years, it was produced only in piece form and in 1965, after the production was transferred to the Tula plant, it began to be issued on a continuous basis. The production of weapons is carried out in modern days.

- massive long trunk, which has a narrowing of 1 mm;
- not too heavy weight.
- the cost is quite acceptable for the MC 21-12 gun. The price is approximately 10000-20000 rubles for used weapons.
All the advantages described above have a great influence on the operation of the hunting rifle MC 21-12. It has a small return, even if you use powerful cartridges, as well as use a sharp, hefty battle that is not inferior even to eminent brands of foreign weapons.
disadvantages
The main disadvantages include the improper operation of automation. That is why weapons and has a lot of negative reviews.
At the development stage, many of the original mechanisms from browning were replaced by simpler ones, since the previous components came out too complex to copy. Subsequently, this affected reliability. MC 21-12 is very sensitive to the quality of the cartridges, namely the calibration of the cartridges, which is why it is necessary to select the appropriate lubricant depending on the season.
Not the best option for a first shotgun
12 is a rather powerful and reliable weapon that is suitable for different types of hunting, where it is necessary to use an additional shot, for example, while hunting geese, ducks, moose or wolves and so on. Of course, the gun is not worth buying as your first weapon, since it is quite difficult to operate. But for an experienced hunter perfect. Even if the weapon was pleasant, then it is obviously not for beginners. Only an experienced person can properly care for him and, if necessary, repair. To understand whether it is possible to buy a gun for a beginner, there is always the opportunity to go to the weapons forum at MC 21-12. Experienced tips will help answer many questions.
If you analyze some publications about this type of gun, you need to listen to the recommendations that are left there. They say that all weapons that are manufactured before the year 89 will have much better quality and reliability, and modern weapons without trial shelling are very unreliable. Of course, in the store there is no way to make such a shelling, and therefore it can be said that in this case you are buying a "pig in a poke." First you need to gain the necessary experience to be able to cope with this type of gun.
In addition, to get some spare parts you will have to try, or even ask a turner for help. Not the easiest to use shotgun MC 21-12. Parts are quite rare.
Description of mechanisms
Automation guns is based on the principle of recoil with a long stroke of the barrel. The trunk is detachable and movable. The sight bar is ventilated. The bore is well and high quality chrome plated. The barrel bore is locked using the bolt of the stop located on the core of the bolt, which is inserted into the hole of the shank on the barrel. The trigger mechanism has a built-in trigger that is mounted on a separate base and is designed to produce only a single shot.
The cartridge case is removed after a shot when moving the barrel to the front position. The design is capable of preventing shots if the bolt in the barrel is not locked. To exclude accidental shots, an automatic fuse is installed, which has a flag type, it will act on the trigger.
The bed is made of beech or walnut, has protrusions for the arm and under the cheek. The fore-end is made removable and fixed on the case of the store with the help of a nut, which has the form of a cap. The store has a tubular shape, it is under-barrel, able to accommodate four cartridges. When the MC 21-12 rifle is being fired, the cartridge is automatically fed from the magazine into the barrel chamber, at which point the bolt moves to the front position. To make the next shot, you should press the trigger.
To turn off the cartridge feed from the magazine, a cutoff has been created. In order to move the shutter to the front position from the rear, you should press the control button.
All external parts of metal parts are decorated with a planar ornament. If the buyer buys a gun souvenir or piece production, then there will be a more thorough decoration of all parts. It will be distinguished by highly artistic manual engraving, and also hand engraving will be present on the outer surfaces of the parts. Masters create very beautiful drawings at MC 21-12. The photo confirms this.

Principle of operation
When a shot is fired, the barrel will be in an engaged state with the bolt in its extreme forward position. The pressure force of the powder gas will be transmitted through the sleeve to the bolt and barrel, reporting movement in the box. The rollback of the barrel and the bolt begins at the moment when the projectile moves along the barrel. When moving the barrel and the bolt to the rear, the cock cockes and the spring contracts.
The movement of the barrel and the bolt in the front side is due to the action of the spring. During the initial movement, the shutter stops due to the suppressor holding the lever, and the barrel continues to move forward. The shutter and the trunk begin to disengage and the trunk is unlocked. The barrel will begin to move forward without the shutter, and on the path of movement it reflects the sleeve from the box and the cartridge feed mechanism is connected, which goes to the feeder tray. The cartridge will move due to the impact of the magazine spring. The return spring is activated and the shutter moves forward, while the tray is fed up and sends the cartridge to the chamber, and then the suppressor tray is recessed down, which leads to the locking of the barrel channel.
When the next shot is fired, the entire cycle is repeated again. After all the cartridges are used up in the store, the shutter will remain in the rear position.
Weapon Rules
Each person who has firearms in his house must be familiar with the operating rules and have with him special reference books on the maintenance of the gun. In no case can you just buy a gun and go hunting without having read all the rules. Otherwise, it will lead to serious consequences, possibly even fatal.
The hunter should ideally know the structure of his weapon, the interaction of all its parts, and also master the control perfectly when charging, shooting and discharging. The toy certainly cannot be called MC 21-12. Photos and videos that are publicly available will confirm this. That is why, before buying, you should familiarize yourself with the rules of use.
Every day you need to check the cleanliness of the bore, bolt, chamber, and other parts. Before shooting, make sure that there is no grease in the barrel bore, and that it should not be in the chamber. In no case should you allow snow, sand or small particles of other origin that may get inside to enter the bore.
It is never possible to check the serviceability and operability of a weapon manually, without firing using cartridges. To check the equipment, you need to have a cartridge with shot capsules that do not have gunpowder inside. This is a kind of layout.
If a misfire occurs, the shutter cannot be opened for several seconds, as a shot may still occur. When removing the cartridge that misfired, be especially careful.
If there is some kind of failure, or if the rifle is malfunctioning, or if some cracks are noticed, then you must immediately stop shooting until all breakages are corrected.
When the shooting is finished, it is necessary to defuse the weapon and make sure that the cartridge is not in the chamber. It is also worth accustoming yourself that when you start shooting, you need to make the same check.
After assembly, always check the operation of the MC 21-12 weapon by moving the moving parts backward, while holding them with your hand when returning to the front position, and after that you can smoothly pull the trigger. Always avoid idling the trigger and do not disassemble if there is no particular need.
Proper shotgun care
Cleaning, inspection and lubrication must be carried out immediately after the shooting. It is necessary to assemble and disassemble the tool in a certain sequence, which is indicated in the passport. In doing so, avoid too much force or shock to the equipment.
Wipe, lubricate or clean the barrel from the chamber side. Repeat lubrication and barrel cleaning on the second, as well as just in case the third day after the last shot. After cleaning, inspect the fabric, which is tightly passed through the bore. Ideally, there should not be soot or lead on it.
When a shot occurs, some part of the powder gas will fall into the box, and therefore it is necessary to carefully clean this part. To clean the grooves, it is necessary to use wooden sticks, after having made the corresponding profile from them.
Lubricating and cleaning the gun, which is stored without use, must be done approximately once every few months. If the weapon is not used for a long time, conservation should be made. Always lubricate parts with a thin layer. The surface should shine from the applied grease. To do this, wet a piece of soft and clean cloth with grease, squeeze it tight and wipe the surface. Too much grease can lead to malfunctions during firing. The grease can clog into the shutter hole for the striker exit, and this often causes a misfire.
If you hunt in humid conditions, in rainy weather or near the sea coast, then you need to lubricate and clean daily, regardless of whether the shot was fired or not.
The barrel channel lead must be removed with a metal brush, which is richly moistened with oil. If there is soot in the bore, then it can be softened with soapy water or a solution of caustic soda. If there is no RH oil, then clean and rinse with ordinary alkaline oil.
In no case when cleaning you can not rest the barrel with a muzzle in the floor. This is due to the fact that the ramrod, like the piston of the pump, is able to draw all dust, crumbs or sand from the floor when entering upward. That is why it is necessary to put something on the floor, for example, an unnecessary magazine or newspaper.
If fresh rust has appeared, then it is worth removing it with the butt of a wooden stick or with a regular cloth that is wetted in oil or alkaline. To soften the rust, soak a rag in oil, and then put the tissue on the affected area and hold for about 10 hours.
If you went hunting in frosty weather, then first you need to give the weapon time to keep warm after frost at room temperature, and only after that proceed with cleaning.
Transportation and storage
The gun must be transported only in a special case. It is also advisable to disconnect the barrel beforehand, as it may be damaged during transportation, which will lead to a number of problems.
In no case should weapons be allowed to fall. In order to prevent mechanical damage, it is worthwhile to apply precautionary measures in advance. Also make sure that the gun is not exposed to various natural precipitation. It is advisable to fix the weapon well with a rope when carrying it in transport.
It is always necessary to keep the gun in a cleaned condition, and also it must be well lubricated. The trigger must always be lowered during storage. Best if the trunk is disconnected.
The storage room should be well heated, with a temperature of at least 10 degrees Celsius.
Cartridges for MC 21-12
The manufacturer allows firing of cartridges that have a standard hunting type. Options usually made at the factory are paper or plastic sleeves. If you independently equip cartridges at home, always check the cartridges against the control sleeve, and pay special attention to the height and diameter of the flange. Those that will be very different must be discarded immediately.
Fraction and gunpowder can be weighed on ordinary scales, pads and wads are selected with the same weight and size. Do not rush to increase the weight of the powder charge if there is an incomplete rollback of the moving part of the gun. First you need to deal with the grease, make sure that there are no gaps.
In no case do not load sporting cartridges that are intended only for the bench gun in the MTs 21-12 hunting weapon. Such cartridges are able to develop a maximum pressure of the powder gases is much higher than the permissible for MC 21-12.
Weapon Issues
Often there is a situation where a shot is fired, moving parts have completed the prescribed cycle, the sleeve flew out of the box through the side window, but the next cartridge did not fall into place, but simply fell to the ground. The hunter at this moment will press the trigger with his finger to make the next shot, but he simply will not follow. To eliminate the cause of such a failure, it is necessary to study the operation of all parts of the weapon.
The cartridge from the magazine will only enter the bottom box window if the feeder tray is in the raised position. The next cartridge will go from the magazine when the barrel turns off the cartridge stop, that is, in the case when the barrel came to the front position without delay. The cartridge must fall into the feeder tray, and it can only lift the shutter. In such a situation, it turns out that the bolt engages with the barrel normally, but too early to fall off the feed lever.
Often, hunters are faced with a different unpleasant situation. The shot was fired, but the cartridge case got stuck in the chamber, and the next cartridge from the magazine rose with the help of the tray onto the delivery line, and the bolt rested against this cartridge while moving forward, and it, in turn, into the cartridge case, which could not get out of the chamber. The main reason for this complication is the discrepancy between the standards of the flanges and the sleeve, as well as a non-calibrated cartridge.
Usually in such situations, the usual reloading of the gun helps, but then the failure can be repeated. In these cases, it is necessary to disassemble the weapon and see all the details, study the degree of wear, carefully check the lubrication, as well as possible clogging. Lubricate and clean all parts well.
At home, the operation of the gun is checked only with the help of layouts. Take about 10 shells that have broken capsules, wipe the soot with a cloth, remove any deformation at the cutoff of the shells, put wood fiber or felt wads, and after the shot, which is suitable for weight, put a gasket and roll it. The value of the wad column is selected in height, which ensures the length of the layout after rolling, which is equal to the length of the cartridge, which is used when firing. The gun is loaded with a breadboard and now you can test the work by moving the moving parts with your hands, resting the butt plate of the buttstock MC 21-12 in any surface.
When you establish the cause of the failure, do not rush to conclusions, it is better to check the performance using the layout several times and make sure that your conclusions are correct. If there is a need for some kind of complicated locksmithing work, as well as replacement of the part, you need to contact a specialized workshop, and not do everything yourself. Of course, this advice is only for people who do not have the appropriate experience.
There are polar opinions about the gun MC 21-12. Reviews are found both negative and positive. One thing is certain with certainty: this is a weapon for professionals. Many people like the cost of the MC 21-12 gun. The price for a used model can be as little as 10,000 rubles.
If you follow all the above rules, you can ensure the failure-free operation of your gun for a long time.
