The SIG556R features a Swiss folding stock, and an M1913 rail for accessory attachment. The 16” barrel features four-groove rifling and a twist rate of 1:9.5”. The SIG556R measures 35.875” but can fold to 26”, making it ideal for situations where maximum maneuverability is required. For Special Forces requiring an accurate, more potent rifle, chambered in 7.62x39mm, the SIG556R sets a new standard for dependable operation and function.
