Description

The invention relates to firearms, in particular to rifles.

A well-known rifle containing a barrel, bolt, trigger mechanism, magazine and butt (SKS-45, "History of Soviet small arms and ammunition", publishing house "Polygon", 1995, p. 83).

With increasing caliber rifle recoil on the arrow increases.

In order to reduce recoil to its full compensation, the powerful rifle is equipped with a barrel, a bolt, a trigger mechanism, a magazine, an additional magazine, an additional bolt, a fixed striker and a movable barrel looking back and connected to a movable striker of the trigger mechanism.

The proposed technical solution is illustrated schematically, where:

1 - trunk;

2 - movable firing pin;

3 - spring striker;

4 - cartridge;

5 - movable barrel;

6 - motionless firing pin;

7 - compensating cartridge;

8 - a bed.

To simplify the shutters, the trigger mechanism and magazines are not shown in the diagram.

Compensating cartridge 7 can be equipped with conventional shot. To synchronize the initiation of cartridges 4 and 7, one of the strikers 2 or 6 may have an adjustment screw.

The powerful rifle works as follows: when you press the trigger of the trigger mechanism, the movable firing pin 2 of the main bolt connected to the movable barrel 5, under the influence of the spring 3, moves in the direction of cut of the barrel of the powerful rifle.

The movable firing pin 2 initiates the capsule of the cartridge 4, and the stationary firing pin 6 at the same time initiates the capsule of the compensating cartridge 7.

With the automatic operation of a powerful rifle, the ammunition 4 is fed from the magazine, and the additional magazine serves to simultaneously feed compensating cartridges 7 into the movable barrel 5 using an additional shutter.

The law of conservation of momentum allows you to compensate for the return completely.

Claims (1)
