A carrier assembly for a gun comprises a gun bolt carrier disposed to reciprocate axially with respect to the central axis of the gun, and a gun bolt disposed to reciprocate axially within the carrier. The gun bolt has a locking groove therein. The assembly also comprises a bolt locking mechanism extending through a portion of the bolt carrier to selectively engage the locking groove and thereby prevent the bolt from moving with respect to the carrier. The assembly further comprises a generally axial groove in a nonreciprocating portion of the gun that engages and selectively rotates the rotatable bolt locking mechanism to selectively lock the bolt to the carrier.
