TACTICAL PRECISION, For 2011, SIG SAUER® is offering several variants to its tactical platforms. NEW to this lineup is our new SIG551-A1, chambered for the widely used 5.56 x 45mm NATO caliber using Swiss Polymer magazines. The SIG551-A1 features a distinctive swiss folding stock, and an M1913 rail for accessory attachment. The SBR 10” barrel features six-groove rifling and a twist rate of 1:7”.
The SIG551-A1 10" SBR measures 29.8” but can fold to 19.7”, making it ideal for situations where maximum maneuverability is required. For Special Forces requiring an accurate, more potent rifle, chambered in 5.56 x 45mm NATO, the SIG551-A1 sets a new standard for dependable operation and function.
