Originally manufactured in 1980 in Germany as a semi-automatic rifle, this item was altered by Vollmer Manufacturing to serve as the host gun for the auto sear listed as item "A" in this lot.

The receiver is in "shelf" configuration, with a functional paddle lever for the magazine catch.

The trigger housing is equipped with an ambidextrous selector and bears pictographic position markings and a cosmetic hinge pin. Internally, the bolt head is dated "IA" to match the receiver, with a full auto pattern bolt carrier marked "HK 9/76".

The serial numbered receiver of this item has not been permanently altered to accept the conversion component, and is not called out by serial number on the paperwork for the conversion component.
