A semi-automatic model of the Swiss SG-510-4 battle rifle, a variant of the Swiss Army's STG-57 rifle. Made with the export market in mind, the 7.62x51 NATO chambered rifle found buyers with Bolivia and Chile, who found the weapon's accuracy ideal in the Designated Marksman role. Post front sight and 600-meter range adjustable peep rear sight, with a 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 and a fancy walnut forearm and buttstock, ribbed steel buttplate and a green canvas sling.

Excellent, with over 98% of the original matte black finish, showing some minor wear on both the barrel and forearm from the bipod, and a few other mild handling marks. Magazine and flash hider not included. Mechanically excellent.
