Originally manufactured in West Germany in 1981, this rifle was subsequently converted to a fully automatic machine gun in HK53 configuration by Fleming Firearms. Still in a "shelf" configuration, the receiver is fitted with hooded post and four-position drum rear sights, a threaded muzzle with flash hider, textured grip and a fixed buttstock with serrated plastic buttplate. The Fleming address is on the right side of the frame, hidden by the trigger housing. There are no visible markings directly on the body of the trigger pack, which is configured for safe, semi-automatic, and full auto, with a right-handed trigger housing marked "0/1/A".
