METHOD OF IMPROVING ACCURACY OF HITS OF SMALL ARMS WITH MOVABLE BUTT Russian patent published in 2017 - IPC F41C7/00 

FIELD: weapon and ammunition.

SUBSTANCE: small arms are made with a movable butt with the possibility of moving the shooting part of small arms relatively to the butt. The weapon contains a trigger coupled by a mechanical linkage element to a spring-loaded butt lock, a lock spring, firing mechanism and a return spring of the butt. To fire a shot, the shooter presses the trigger, which releases the spring-loaded lock, the lock, under the action of the lock spring, first disconnects the butt with the shooting part of the weapon, and then releases the firing mechanism from the cocking notch, and the shot fires, shooting part of the weapon moves relatively to the butt in the direction of the butt, acting on the butt lock, which compresses the spring of the lock and the return spring of the butt, as a result of which it establishes the lock of the butt to the starting position. After that, the return spring of the butt returns the shooting part of the weapon to the before the shot position and at the same time the firing mechanism is cocked by an element of the mechanical connection.

EFFECT: increasing the accuracy of hits.
