The sear is individually marked, and installed in the shelf-pattern trigger pack in item B of this lot; the B item is listed by serial number on the ATF tax stamp paperwork in field 4h, but B is not itself the registered item.

Originally manufactured in 1982 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. Post front and 4-position drum rear sights, with a Fabian Brothers muzzle brake on the threaded muzzle, "ICV" marked barrel, triangular handguard, textured pistol grip, and a two-position telescoping buttstock. The receiver is "shelf" pattern, with a functional paddle lever for the magazine catch and model/importer markings on the magazine well. The trigger housing is equipped with a right handed selector and bears "0/1/25" markings. The bolt carrier was originally semi-auto pattern, with a welded-up trip sear, "WZA" on the back, a plastic recoil buffer, and "IB" (1981) dated bolt head.
