Originally manufactured in 1984 and later upgraded, notes from the consignor indicate that this weapon was originally supplied to an unnamed police department, where it "didn't see much use, if any". Short barreled 5.56mm automatic rifles have been seeing growing popularity in the Armed Response/SWAT role, giving many of the size/maneuverability advantages of a pistol caliber sub-machine gun combined with increased range and hitting power. Hooded post front and four-position drum rear sight, with a Knight's Armament Rail Adaptor System installed in place of the forearm, birdcage flash hider, three position "0/1/25" (safe/semi/full) hinge pin configured trigger group and a fixed buttstock. The magazine well bears the HK nomenclature and "IE(antler)" (1984) date code on the left side, with the West Germany/Chantilly, Va address on the right side. One magazine is included, gray steel and "IE" (1984) dated. Also included with the item are three Knight's brand rail covers, a green canvas sling and a slim checkered handguard with vertical hand stop.
