With aesthetic and mechanical parallels to both the U.S. Thompson submachine gun and weapons like the Lewis Gun, the American 180 M2 uses a top mounted spring loaded "platter" magazine to feed an open bolt selective fire mechanism, with aluminum receiver construction. Capable of a 1200 RPM cyclic rate, the low recoil of the 22LR cartridge makes for a weapon that's far easier to control (and far easier to feed, cost wise) than many automatic weapons. The 180 was evaluated by the U.S. Army for use in close combat; while unsuitable for general infantry use, within "knife fighting range" the 180's extreme precision would allow multiple rounds to bore through a single point of armor or structure, giving a penetrating power beyond what one would expect from the humble Long Rifle cartridge. Blade front and adjustable peep rear sights, with a set of protective wings and cooling fins on the barrel, non-reciprocating charging handle, and a smooth synthetic forearm, pistol grip and detachable buttstock. Included with the lot are four magazines, one blued steel (with spring unit) and three clear plastic (sans spring units). The top receiver cover is absent.

Very fine, incomplete, with 90% plus original blue finish, showing light handling marks and edge wear overall, along with a few light scratches on the furniture. The steel magazine has a damaged spring catch, and the plastic magazines are a bit ill fitting. Cannot be fired without top cover, but mechanically appears to be in good order. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.
