 The machine gun is fed from an open-link disintegrating M27 ammunition belt that can be strung loosely from the feed tray or placed inside a 100 or 200-round disposable plastic container, which is then clipped to the left side of the receiver.This ammunition container has a transparent rear wall that allows the gunner to monitor ammunition levels visually.Belt movement is carried out by a pawl-type feeding mechanism, which was modeled on the MG 42's feed system.
