摘要： An ammunition magazine box is provided for receiving a vertically serpentined length of belted ammunition for selective outfeed from the box to a machine gun. A specially designed support bracket structure, representatively of a length adjustable construction, is provided and suitably secured within the interior of the magazine box. At least a portion of the belted ammunition loops rest on a top side surface of the installed support bracket structure. The top support bracket structure side surface is (1) laterally sloped, in a direction transverse to the lengths of the belt loops, to inhibit a tilting-created intermeshing of vertically adjacent projectile ends of the ammunition rounds which could cause a feed jam, and/or (2) longitudinally sloped, in a direction parallel to the lengths of the belt loops, to desirably lessen the ammunition outfeed force that must be exerted by the machine gun.

摘要： To safely and reliably hold the forwardly spring-biased bolt assembly of a machine gun in a rearwardly disposed position within the receiver portion of the gun, a specially designed locking apparatus is mounted on an exterior side surface portion of the receiver. The locking apparatus has a slot therein which is operative to rearwardly receive a bolt pin portion of the bolt assembly which is anchored to the bolt assembly for reciprocating motion therewith and projects outwardly through a sidewall slot in the receiver for reciprocating motion with the bolt assembly. To releasably lock the bolt assembly in its rearward position the bolt pin is rearwardly moved into the locking apparatus slot, and a latch portion of the locking apparatus is moved to block forward exit of the pin from the locking apparatus slot.
