The SOCOM 16 and SOCOM II are largely identical to the standard M1A, but feature a barrel, rather than the standard model's barrel. The specially designed muzzle brake is designed to reduce the increased recoil produced by the shorter barrel. In addition to the top accessory rail for optics, the rifle has enclosed Garand-style iron sights, with tritium inserts for low or dim light conditions. The rifle will accept any M14 magazine, with typical capacities of 5, 10, or 20 rounds.
