The principle of operation
The design of the gun is simple, very unpretentious, so the key when handling a shotgun is not the application of excessive effort. With proper implementation of user effort is not needed.
Charging the carbine is as follows:
- turn the release lever to the right to the limit;
- rotate the barrels down until it stops;
- consistently put the bullets in the chamber;
- return the stems to the original position. The release lever should occupy a Central position, if you focus on the shank. If not, the lever is adjusted by hand.
Special attention should be paid to manipulations with changeable chokes. In this procedure, you need to fulfill a number of requirements:
- all manipulations must be carried out only on the discharged rifle;
- before each firing and after the change of contraction to check how well prolonged the contraction. To tighten use a special key from the kit. With insufficient tightening of the powder gases burst into the gap between the constriction and the barrel, which leads to deformation of the parts and even the departure of narrowing;
- changeable muzzle narrowing must be flush relative to the muzzle or a little sink;
- muzzle narrowing screwed up to the stop end of the projection on the barrel, but between the trunk and the narrowing of the gap remains;
- after installation, the channel is visiting: at the point of contact of the end of the contraction and protrusion of the channel must be seen ring. If the integrity of the ring, this means the deformation of the constriction or seats. The shooting in this case is prohibited.
The tightness of the muzzle of the contractions need to check after 50-100 shots.
For care of rifle periodically procedure partial disassembly. The procedure is as follows:
- inspect the chamber for any bullets. Withdraw them;
- pull the forearm latch on the lower surface and turn the front end of the forend from the barrel. Disconnect the shank;
- turn the lever of constipation in the top of the box to the right. Rotate the barrels down until it stops and is disconnected from the box;
- if you want to clean and lubricate the firing mechanism, proceed as follows: Unscrew the screws and separate the head from the butt, turn the retaining screw and remove the bushing. Unscrew the screw which passes through the butt, and then slightly hit the box on a wooden surface to loosen the connection of the butt and box. Then remove the butt.
Assembly Mr-43 KN in the reverse order. Complete disassembly is required only if damaged or very dirty rifle.
For cleaning and lubrication will need gun oil, rags, brush and cleaning rod.
A large field of activity for tuning no. It is possible to replace the butt on a piece of wood or with a more interesting ornament.
