Automatic firearm with a bolt assembly that moves between a closed position and an open position

摘要

An automatic firearm with a bolt assembly which is moveable along a bolt assembly motion path between a closed position and an open position, a magazine which advances cartridges by spring force across the bolt assembly motion path into this motion path, and a lock which only allows the first cartridge of magazine to advance into the bolt assembly motion path when the bolt assembly is situated in or near its open position, is disclosed. The lock is preferably created by a plate that extends parallel to the bolt assembly motion path and is mobile in its direction of extent, is pushed between the first cartridge and the bolt assembly motion path, and holds back the cartridge until the bolt assembly has reached or almost reached its open position.
