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 rifle’s 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 optional flip up front combat sight is adjustable for windage and elevation. 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. In addition to the standard model SIG 556 which will begin to ship in late Fall of 2006, SIGARMS will also offer the SIG 556 SWAT. The SWAT model will feature the same compact design of the standard SIG 556 with 16” barrel but will feature a flat top Picatinny railed receiver and a tactical quad rail. These two rifles are the first of several new SIG 556 models that are currently in development at SIGARMS. The wait is over. The new U.S. made SIG 556 begins shipping in late Fall – because the time has come.
