Sig Sauer Rifles

Sig Sauer Rifles are semi-automatics that inspire shooters around the world. The SG 550 series is based on the celebrated rifles once restricted to law enforcement and military made by Sig affiliate, Swiss Arms. The performance, accuracy and dependability of these rifles were field-proven time and again. Sig Sauer produces the U.S. versions of these outstanding firearms, the SIG556s. In a 556, a gas piston operating rod system joins unique trigger housing in a lighter weight firearm that loads up with AR-15 magazines. Built in the Swiss tradition, yet with its own advanced characteristics, the 556 series of rifles is a crowning achievement. As your leading Sig distributor, we’re here to supply rifles, handguns, and Sig Sauer parts.

Sig 556 Rifle Unites Classic Elements and Tactical Innovation

The SIG 556 Classic is a rifle tactical shooters rely on regularly. The Classic model also shares Swiss elements, such as an adjustable stock that folds in and locks up. This rifle gives users an innovative grip for improved control. The SIG 556 rifle operating system supports target acquisition with its red dot sighting system. Sig’s Classic SWAT rifle expands on the Classic. A quad-rail hand guard supports tactical equipment and rear rotary diopter delivers sight pictures.
