AUTOLOADING GUN Russian patent published in 2018 - IPC F41A3/26 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to weapons, namely autoloading guns. Autoloading guns contain a barrel with a chamber, fore-end, an automatic mechanism for unlocking and locking the chamber, extracting the cartridge case, cocking the trigger and feeding the cartridge into the chamber. Mechanism of automation includes a bolt, a shutter frame and an elastic element. Magnitude of the stroke of the gate in the gate frame before the completion of the working compression of the elastic element in the process of pulling back the gate is greater than the value of the working stroke of the elastic element. Movement of the slide frame in the rolling is limited by the interaction with the box in the extreme forward position of the shutter frame, which limits the movement of the shutter in it. Breech block is provided with a barrel stop for the interaction of the trunk with the end face of the box in its extreme rear position.

EFFECT: increase in the reliability of the functioning and manufacturability of weapons manufacturing, simplification of the design of weapons is achieved.
