MC 21-12 is very sensitive to quality of ammunition, namely calibration cases, it is therefore necessary to find a suitable grease depending on the season.

Not the best option for a first rifle

Working Principle

the Gun in parsing

When it fires, the barrel will be in a coupled condition with the bolt in the forward most position. The pressure of the powder gas will be transmitted through the sleeve on the slide and barrel, reporting the movement in the box. The back trunk and paddle starts at the moment when the movement of the projectile down the barrel. When moving the barrel and bolt toward the rear, the hammer is cocked and the spring is compressed.

The Movement of the trunk and bolt in the front is due to the impact of the spring. During initial movement of the shutter stops because of the retention lever suppressor, and the barrel continues to move forward. The slide and barrel begin to disengage and the unlocking of the barrel. The barrel will move forward without the bolt, and the movement reflects a sleeve from the box and connecting the feed mechanism of the cartridge that goes on the tray feeder. The cartridge will move due to the impact of the spring store. Activated the recoil spring and the bolt is moved forward, wherein the tray is fed up and sends a cartridge in the chamber, and then comes the retraction of the tray suppressor down, which leads to locking the barrel.

When is the next shot, the whole cycle repeats again. After all the cartridges are in the store spent, then the shutter will remain in the rear position.

The Rules for handling weapons

Rifle

Every person in your house has a firearm, should familiarize themselves with the rules of operation and to have special reference books on the content of the gun. In any case, you can't just buy a gun and go hunting without knowing all the rules. Otherwise it will lead to serious consequences, perhaps even fatal.

The Hunter should ideally know the device of your weapons, the interaction of all its parts, as well as to master control when charging, firing and unloading. Toy certainly can not be called MC 21-12. Photos and videos that are in the public domain, to confirm this. That is why before buying you should read the terms of use.

Every day you need to check the cleanliness of the barrel, breech, chamber, and other parts. Before shooting is to make sure that the barrel is no lubrication and it should not be in the chamber. In no case should not be allowed to into the barrel fell on the snow, sand or small particles of another origin, which can get inside.

Never to check the condition and serviceability of weapons manually, without shooting with the use of cartridges. To check out equipment, you need to have the cartridge with the spent primers that do not have inside powder. This kind of layout.

If there is a misfire, it is impossible to open the shutter for a few seconds as it may still be shot. When you remove the cartridge that misfired, take special care.

If there is some failure or noticed the malfunction of the gun, or noticed any cracks then you must immediately stop shooting until you fix all the breakage.

When the shooting is over, you need a weapon to defuse, and make sure that the cartridge is not in the chamber. It is also worth to train yourself that when you start shooting, you need to make the same check.

After Assembly, always test your weapons MC 21-12, by separating the moving parts back, and hold their hand when returning to the forward position, and to produce a smooth trigger pull. Always avoid idle trigger pull and do not perform disassembly, unless it's absolutely necessary.

Proper care of a gun

MC 21-12

The Cleaning, inspection and lubrication should take place immediately after the shooting took place. To assemble and disassemble the tool needed in a certain sequence, which is specified in the passport. At the same time avoid too much effort or impact equipment.

Wiping the lube or the barrel cleaning produce from the chamber end. Lubrication and cleaning of the barrel, repeat for the second, and in any case the third day after the last shot. After cleaning, inspect the fabric, with a tight course passed through the bore. Ideally, it should not have soot or eventsevery.

Occurs When shot, some part of the propellant gas will get into the box, and therefore must be carefully cleaned this item. To clean grooves, you need to use wooden sticks, pre-making them suitable profile.

Grease and cleaning guns, that is without applying, you need to make about once every few months. If the weapon is long time not in use, should be made conservation. Lubricant on parts always apply a thin layer. The surface should glisten from the applied lubricant. To do this, cut soft and clean cloth wetted with lubricant, tight squeeze and wipe the surface. If too much lubrication, it can lead to failures when fired. Grease can hide in a hole under the shutter release the striker, and it often causes a misfire.

If you hunt in humid environment in the rainy weather or near the coast, lubrication and cleaning is carried out daily, regardless, made the shot or not.

Svintsovo of the barrel need to be removed with a metal brush, which is heavily soaked with oil. If there is soot in the barrel, its softening using soapy water or a solution of caustic soda. If there is no oil RJ, then the cleaning and rinsing produce conventional alkaline oil.

In Any case when cleaning not to rest the barrel muzzle cut in half. This is because the cleaning rod as a piston pump, when you sign up able to pull from the floor all the dust, crumbs or sand. That is why floors need to enclose, for example, unnecessary magazine or newspaper.

If there is fresh rust, you should remove it by the end of the wooden sticks or plain cloth that is moistened with oil RJ or alkaline. To soften the rust, soak a rag in oil, and then put the cloth on the affected area and hold for approximately 10 hours.

If you go out hunting in cold weather, then you first need to give the gun time to warm up after the cold room temperature, and then to begin cleaning.

Transport and storage

The Gun must be transported only in a special case. And also it is advisable to disconnect the trunk may damage it during transport, leading to several problems.

gun Barrel

In Any case it is impossible to prevent the fall of the weapon. To prevent mechanical damage, it is recommended to apply precautionary measures. Make sure that the gun is not subjected to the action of various natural rainfall. Preferably fix the weapon with a rope when taking him to the transport.

You should Always store the gun in a purified state, and it must be well lubricated. The trigger must always be in lowered position during storage. It is best if the trunk is disconnected.

The storage Room should be well heated, with a temperature below 10 degrees Celsius.

The Ammunition for the MC 21-12

The manufacturer allows fire cartridges that have a standard hunting type. Factory options are usually made with paper or plastic liners. If self equip ammo at home, always inspect the sleeve for the control sleeve, and pay special attention to the length and diameter of the flange. Those will be very different should be immediately discarded.

The Shot and powder weighed on ordinary scales, liners and wads are selected with the same weight and size. Do not rush to increase the weight of the powder charge, if there is a partial rollback of the movable part of the gun. First we need to deal with grease, make sure there are no gaps.

In Any case, do not charge in a hunting gun MC 21-12 sports cartridges that are intended only for bench guns. Such cartridges are capable of developing maximum pressure of the powder gases is much higher than allowable for MC 21-12.

The Problem of arms

Often a situation when the shot came, moving parts made the prescribed cycle, the shell casing flew out of the box through the side window, but another patron did not get to his place and just fell out on the ground. Hunter at this point, press your finger on the trigger to make the next shot, but it simply does not follow. To address such a failure, it is necessary to study all parts of the weapon.

A round from the magazine will fall into the lower window of the box only if the feeder tray is in the raised position. The following cartridge will go out of the store when the gun will turn off the stop of the cartridge, i.e. in the case when the trunk is in the front position came without delay. Chuck needs to get to the tray feeder, and he can only pull the shutter. In such a situationit turns out that the shutter is locked with the barrel fine but too early off the arm of the feeder.

Hunters Often are faced with another unpleasant situation. Shot made, but the casing stuck in the chamber and the next round from the magazine went up with the tray on the line chambering and the shutter when moving forward rested this cartridge, and he, in turn, in a casing, which has failed to exit the chamber. The main reason for this complication is the disparity between the standards of flanges and casings, as well as uncalibrated cartridge.

Typically in such situations the usual reloading of the gun, but then the failure can be repeated. In these cases it is necessary to dismantle the weapons and to see all the details, to check the degree of wear, check carefully the grease and possible contamination. Good lubricate and clean all parts.

At home tested the gun only with the help of the layouts. Collect about 10 shells that have broken caps, wipe cloth Nagar, correct the deformation in the cut of the sleeves, put wood-fiber or felt wads, and after a fraction, which is suitable for weight, put the gasket and Zavolzhye. The value of the column of wads selected for height, which provides the length of the layout after rolling, which is equal to the length of the cartridge that is used in the shot. The gun is charged with the layout and now you can test the operation by moving the moving parts with your hands, resting the butt plate MC 21-12 in any surface.

When establish the cause of failure, we should not jump to conclusions, better check the performance by using the layout several times and make sure sure of the correctness of their conclusions. If you need any complex plumbing work and replacement parts, you must contact a specialized workshop, not to do everything yourself. Of course, this advice is only for people who do not have relevant experience.

There are polar opinions about shotgun MC 21-12. Reviews are both negative and positive. With confidence we can say one thing: this is the gun for professionals. Much like the cost of shotguns MC 21-12. The price for a used model may be only 10,000 rubles.

If you follow all the above rules it is possible to ensure trouble free operation of your gun for a long time.
