A semi-automatic commercial export model of the Swiss SG-510-4 battle rifle, the AMT (American Match Target) was imported in very small quantities by Benet Arms in San Francisco in the late 1960s/early 1970s. In keeping with Swiss military tradition, the 510-4 was built for ranged precision while still being a rugged infantry rifle capable of handling the harsh conditions of alpine warfare and was sought out by nations such as Bolivia and Chile for issue as designated marksman weapons. Post front sight and 600-meter range adjustable peep rear sight, a bird cage flash hider on the threaded muzzle, swiveling bipod mounted at the front of the ventilated handguard, and a folding carry handle. The receiver is equipped with a "T" shaped cocking handle, flip-down winter trigger, "S/1" marked 2-position selector and "Benet Arms./S. F. Cal./94-4079" on the left side of the trigger group. Equipped with a ribbed plastic pistol grip, a fancy walnut forearm and buttstock, and a ribbed steel buttplate. Also included with the rifle are two brown canvas slings, three extra original magazines (two 10-round and one 5-round), an advertising flyer, and two instruction manuals.

Excellent with 98% plus original blue and black finish showing minor edge and high spot wear, evidence of light test firing, and finish loss around the edges of the magazine well. The wood is excellent with a few light pressure dents on the forearm from the bipod. Mechanically excellent.
