Now In Stock!. New Sig 556 16" Rifle With Sights. Sig556006. The time has come. No other semi-automatic rifle has captured the imagination of the shooting public like the SG 550 series rifle. For years this legendary Swiss made rifle has been restricted to law enforcement and military sales where it has continuously built on its reputation for outstanding performance, accuracy and durability. Now, SIGARMS has undertaken development and production of a U.S. made version. SIGARMS introduces the new SIG 556. The SIG 556 features the same high-performance two position adjustable gas piston operating rod system engineered by SIG's sister company Swiss Arms and marries it to a trigger housing that not only cuts the rifles weight by a pound but is designed to accept standard AR magazines. The SIG 556 features a 16" military grade cold hammer forged barrel, chambered in 5.56mm NATO, with a twist rate of 1 in 7. The forearm housing the gas operating system is a vented non-slip polymer featuring the SIG TriRail design with three integrated Picatinny rails for mounting accessories. The Picatinny rail equipped receiver is made of high strength carbon steel with a durable wear-resistant Nitron X rifle finish. The trigger housing is made from a heat treated aircraft grade aluminum alloy with a hard-coat anodized finish designed to survive extreme conditions. The rifle comes equipped with a smooth two-stage trigger. The SIG 556 also features an ambidextrous safety and is designed to accept standard AR magazines. A 30-round magazine is supplied with each rifle. Spare battery compartments are provided in the ergonomically designed pistol grip as well as the rubber padded watertight adjustable butt stock. The butt stock also offers sling attachment points
