New SIG 556 SWAT - SIG SAUER® introduces the next version of this legendary Swiss rifle.

EXETER, NH – 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, SIG SAUER® has released the next model in the 556 family, the SIG 556 SWAT.

Like the SIG 556, the SIG 556 SWAT highlights 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 SWAT has a 16” military grade cold hammer forged barrel, chambered in 5.56 NATO, with a twist rate of 1 in 7”.  The high performance flash suppressor provides enhanced flash reduction and includes 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 aftermarket accessories.  The vented tactical quad rail forearm is machined from aircraft grade aluminum alloy and hard coat anodized for durability.  The quad rail has 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 complete with a 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 is equipped with a smooth two-stage trigger, ambidextrous safety and is designed to accept standard AR magazines.  A 30-round magazine accompanies each rifle.  The rifle is outfitted with a MAGPUL CTR Carbine Buttstock.  This buttstock is adjustable for multiple lengths of pull and includes a unique locking mechanism that friction locks the stock to the receiver extension for zero movement.  The ergonomically designed pistol grip has an integrated storage compartment.  The rifle also includes the Grip-light vertical forend grip with an integrated, removable tactical LED flashlight and mounts directly to the quad rail forends.
