Sig Sauer SIG556 HOLO Rifle, .223 Remington, 30 Rounds, 16" Barrel, Holographic Red Dot Sight, Vented Tri Rail Forearm, Black Adjustable Folding Buttstock.

The SIG556 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-15 magazines. The SIG556 features a 16" military grade cold hammer forged barrel, chambered in 5.56x45mm NATO, with a twist rate of 1:7". The A2 flash suppressor retains a standard 1/2x28 TPI thread pattern, ensuring compatibility with aftermarket accessories.
The vented tactical tri rail forearm provides the same overall feel of the Classic SIG556, but with the added utility of three accessory rails. The picatinny rail equipped receiver is made of high strength carbon steel with a durable wear-resistant Nitron finish. The rifle comes standard with a flip up combat front and rear sight system and a holographic red dot sight. 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-15 magazines. A 30 round magazine is supplied with each rifle. The rifle has an M4 type collapsible and folding buttstock. The ergonomically designed pistol grip features an integrated storage compartment.
