A bolt assembly for a firearm is constructed with three locking lugs, one of which is oriented down in unlocked condition as it is withdrawn past the magazine of the firearm. The body of the bolt is of reduced diameter with respect to the bolt head which carries the locking lugs. A cartridge depressor is mounted in association with the bolt body to effectively increase the diameter of the bolt body in the vicinity of the magazine to that of the bolt head.
