Steyr AUG

The federal regulation names the AUG's receiver outright — and the surplus kits sold to build one arrive with the military's select-fire trigger pack in the box.

The Austrian bullpup from Steyr's 1974 patents to the Alabama-built A3 M2, its export history from Lithgow to Kuala Lumpur, and its mechanism from the maker's own manuals — with an import-kit build under US and Michigan law: the receiver the regulation names, the §922(r) count, and the select-fire parts in the box.
