Originally manufactured in 1980 in Germany as a semi-automatic rifle, this item was altered to serve as the host gun for the auto sear listed as item "A" in this lot. Features a hooded post front and four-position drum rear sights, flash hider on the threaded muzzle, "IAG" marked barrel, triangular handguard, textured pistol grip, and a two-position telescoping buttstock. The receiver is in "pin" configuration, with a functional paddle lever for the magazine catch. Model/importer markings on the magazine well. The trigger housing is equipped with a right handed selector and bears "S/E/F" markings. The bolt carrier was originally semi-auto pattern, with a welded-up trip sear, "HK 9/76" on top, and an undated bolt head. Included with the item are two extra magazines, a sling swivel-equipped endcap, and a modern hard case.

The serial numbered receiver of this item has been permanently altered to accept the conversion component, and is called out by serial number on the paperwork for the conversion component.
