No other semi-automatic rifle has captured the imagination of the shooting public like the SG 550 series rifle. The SIG556 is built around a reliable gas-operated system with a rotating bolt. It 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. This rifle has a hooded blade front sight, a flip-up adjustable rear sight, and a 10-round magazine and comes with the original factory hard case. Its stock, metal, and bore are all in very good condition.
