Manufactured 1980-1981, this is a variant of the Thompson Submachine Gun scaled down and adapted to run on the 22 Long Rifle cartridge. The core operating mechanism is open bolt blowback, just like the classic model, though many major components are made with aluminum instead of steel to keep the weight down. In handling and appearance it is a faithful re-imagining, with a fixed blade front sight on the Cutts-style compensator, fluted barrel, and a peep rear sight concealed by the protective wings. Markings are traditional in layout, with appropriate changes for model and caliber. Fitted with a grooved horizontal forearm, pistol grip and a quick detach stock. One magazine, made by using a classic-style 45 ACP "stick" magazine as a housing for the 22 LR assembly, is included.
