Find Dealer
TACTICAL PRECISION. 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, aluminum quad-rail forend for mounting accessories and an M1913 top rail for sight attachment. The SBR 10” barrel features six-groove rifling and a twist rate of 1:7”.
The SIG551-A1 SWAT 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.
