The FN SCAR is the semi-auto only version of the newest service rifle of US special operators. Light, fast-handling and quick shooting, the FN SCAR 16S is chambered in 5.56x45mm and features a cold-hammer forged barrel. Fully-ambidextrous operating controls instantly adapt to any shooter and any shooting position. The optical rail and three accessory rails enable the mounting of scopes or electronic sights, plus tactical lights and lasers. The polymer stock is fully adjustable for comb height and length of pull. The FN SCAR series of short-stroke, gas piston-operated rifles have the distinction of being the semi-auto version of the very rifles carried by USSOCOM. The SCAR 16S and 17S, chambered in 5.56x45mm and 7.62x51mm, respectively, feature cold hammer-forged, chrome-lined, MIL-SPEC, free-floating barrels. Fully ambidextrous, the controls adapt to any shooter in any shooting position. The polymer stock is telescoping, fully adjustable for length of pull and comb height, and folds to the side for storage. The receiver incorporates a MIL-STD 1913 optical rail. Three rails (at 3-, 6-, and 9-o'clock) mounted forward of the magazine well permit the mounting of accessory optics, lights, and lasers. Both models incorporate a gas regulator, enabling the shooter to adjust gas flow for optimal operation when firing with a suppressor. Both models are available in matte black and FDE.
