For years, the Swiss-made SIG556 has continuously built on its reputation for outstanding performance, accuracy and durability. The SWAT is a semiautomatic rifle with the silhouette that harkens back to the original military-only 550 model. Featuring a full length gas piston operating system with a 2-position gas valve, the rifle will keep operating even when the environmental conditions deteriorate. Available in 5.56 NATO, the SWAT features a Swiss-type folding stock that adjusts to length, as well as a aluminum quadrail forend that is ideally suited for mounting accessories. The SWAT's sleek profile and compact length is enhanced by a 16" cold hammer-forged barrel with a 1 in 7" twist. This rifle features a muzzle-brake, a rotary rear sight, a quad-rail mounting system, and an extended recoil pad and includes the original factory hard case and paperwork. Its stock, metal, and bore are all in very good condition.
