The FN SCAR 16S is the semi-automatic version of the US Military's MK 16. Light, fast-handling and quick shooting, the FN SCAR 16S is chambered in 5.56x45mm and features a free-floating, cold hammer-forged MIL-SPEC barrel with chrome-lined bore and chamber. Fully-ambidextrous operating controls instantly adapt to any shooter and any shooting position. The receiver integrated MIL-STD 1913 optical rail and three accessory rails enable the mounting of scopes or electronic sights, tactical lights and lasers. The telescoping, side-folding polymer stock is fully adjustable for comb height and length of pull.
