SIG 556 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. SIG SAUER® offers the U.S. produced version as the SIG 556, which is available to the general consumer and law enforcement markets. 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.
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.
