Cartridge/carrier locking device for automatic gun

摘要

A cartridge/carrier locking device for an automatic gun including a latch plate pivotally mounted on an inner wall of a receiver to pivot in a seesaw like manner to have two ends thereof alternately protrude inside of the receiver. The front end protrudes to restrain a cartridge and the rear end to restrain a carrier. A spring pushes the rear end toward the inside of the receiver. Against this spring, a breechblock and a cartridge brought out of a magazine respectively restrict the protruding motion of the rear end until the breechblock moves backward approximately to a maximum extent. The position at which the breechblock comes to restrict the protruding motion of the rear end of the latch plate is arranged to differ from the position at which the cartridge comes to restrict in such a way as to allow the rear end to lock the carrier.
