This is a very rare semi-automatic commercial model of the Swiss Sturmgewehr 57 that remained in use until approximately 1980. These were imported for only a very short time in the early 1980s, thus making them very scarce and desirable on the collectors market. Adjustable blade front and peep rear sight, both folding, with the "Swiss cross in shield" marking on top of the receiver, carry handle, matching numbers on the receiver and stock. Integral muzzle break and bayonet lug. Fitted with a winter style flip down extended trigger. Vented metal handguard with folding bipod and ribbed rubber grip section, serrated pistol grip, and straight rubberized buttstock. Includes bayonet and sheath, cleaning kit, and three magazines. Front and rear trunnions are seam welded to a possible "rear" sheet metal receiver section.
