SIG556 SWAT SIG556 SWAT Like the SIG556, the SIG556 SWAT 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 SIG556 SWAT features a 16” military grade cold hammer forged barrel, chambered in 5.56mm NATO, with a twist rate of 1 in 7”. The high performance flash suppressor provides enhanced flash reduction and features an ACME type thread for compatibility with select industry sound suppression devices. The flash suppressor retains a standard .5 x 28 TPI thread pattern, ensuring compatibility with after-market accessories. The vented tactical quad rail forearm is machined from aircraft grade aluminum alloy and hard coat anodized for durability. The quad rail features four integrated Picatinny rails for mounting a wide range of accessories. The Picatinny rail equipped receiver is made of high strength carbon steel with a durable wear-resistant Nitron® X rifle finish. The rifle comes standard with the flip up combat front and rear sight system. The trigger housing is machined from an aircraft grade aluminum alloy forging with a hard-coat anodized finish designed to survive extreme conditions. The rifle comes equipped with a smooth two-stage trigger, ambidextrous safety and is designed to accept standard AR magazines. A 30-round magazine is supplied with each rifle. The rifle features the MAGPUL CTR Carbine Buttstock. This buttstock is adjustable for length of pull and features a unique locking mechanism that friction locks the stock to the receiver extension for zero movement. The ergonomically designed pistol grip features an integrated storage compartment. The rifle also includes the Grip-Light vertical forend grip which features a removable tactical LED flashlight and mounts directly to the quad rail forends. Select versions feature a folding stock with the ability to collapse, providing he best of both worlds.
