Abstract: A two-barreled machine gun has two fixed firing chambers, a conveyor, and a feed system mounted within a housing. The feed system transfers ammunition from the conveyor to the firing chamber. The feed system includes a sprocket barrel pivotably mounted about its central longitudinal axis. The sprocket barrel has two receptacle slots and two discharge slots circumferentially spaced thereabout. The sprocket barrel is rotatable between a first and second position. The receptacle slots each have a first position aligned with the conveyor to receive a round of ammunition and a second position aligned with a respective firing chamber. One receptacle slot is in its first position when the other is in its second position. The discharge slots also have a first position aligned with the firing chambers and a second position aligned with an outlet in the housing. One discharge slot is in its first position when the other is in its second position.

Abstract: A termination accumulator for a machine gun has a handling conveyor passing through a supply channel, a bypass channel, and a return channel. The supply channel leads to a feed system of a machine gun. The bypass channel has its other end connected to a return conveyor leading from the feed system. A gate is mounted at the junction of the bypass channel and supply channel operably between two positions, one position directs ammunition on the handling conveyor onto a supply conveyor leading to the feed system and a second position directs ammunition on the handling conveyor through the bypass channel. Upon release of a trigger mechanism operably connected to the gun, the gate moves from its first position to a second position such that the feed system continues its forward operation to clear itself of any live ammunition therein. The handling conveyor maintains a forward mode directing ammunition in to the bypass channel.
