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 before being banned by the 1984 assault rifle bill. Adjustable blade front and peep rear sight, both folding, with the "Swiss cross in shield" marking on top of the receiver, matching numbers on the barrel shroud, receiver and stock, and 2-position selector switch. Integral muzzle break and bayonet lug. The upper receiver is fitted with a stamped and welded steel scope base and a scarce Kern Aarau 4x24 sniper scope 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 a Blackhawk Sportster soft case and four extra 24-round magazines.

Excellent. 99% original finish remains with scattered light handling marks, and some small surface scratches. The grip and stock are very good with handling marks and light abrasions on the end of the grip. Mechanically excellent. The optics are very clear, though it appears the tritium element of the scope is no longer illuminating. A scarce rifle with an equally scarce scope, sure to fit well in any military or SIG collection.
