Abstract: A suppressor assembly includes a suppressor that is mounted by rails slidingly received by the barrel clamp of a multi-barreled rotary machine gun to accommodate movement of the suppressor between a latched, operative position projecting beyond the barrel muzzles, effective to suppress blast pressure and flash incident to gun firing, and a latched, stowed position restoring the gun to its normal barrel length.

Abstract: A magazine is provided with anti-syphon members, mounted atop the partitions of a multi-bay magazine, which operate in conjunction with drag-reducing rollers to prevent spurious syphoning movements of an ammunition belt from one bay to an adjacent bay as the belt is being withdrawn from the latter to a magazine exit port. To provide for bidirectional ammunition belt withdrawal, the anti-syphon members are pivotally mounted in pairs operating to permit belt withdrawal from the bays over the rollers and directly to an exit port, while inhibiting syphoning belt movements from bay to bay.

Abstract: An ammunition magazine assembly is provided with a plurality of permanent partitions for subdividing the magazine interior into a plurality of bays and a plurality of optional separators readily removably installed to subdivide selected bays into bay sections. The bays accommodate belts of large caliber ammunition, while the bay sections accommodate belts of small caliber ammunitions. The magazine box is further equipped with a plurality of operational exit ports, all capable of accepting either a modular closure cover or a modular feed chute for either large or small caliber ammunition. The magazine assembly is thus readily adapted to bidirectional feeding of an ammunition belt or belts of one caliber or bidirectional feeding of belts of different calibers.
