THE LEGEND CONTINUES, The legendary performance and accuracy of the Swiss-built SG 550 tactical rifle is found in every SIG556 Classic. The Classic is a semi-automatic rifle with the silhouette that harkens back to the original military-only 550 model. Featuring a full length gas piston operating system with a 2-position gas valve, the rifle will keep operating even when the environmental conditions deteriorate. Available in 5.56 NATO, the Classic features the original Swiss folding stock, as well as a polymer ergonomic forend.

The Classic’s sleek profile and compact length is enhanced by a 16’’ button rifled barrel. SIG SAUER shaved a pound off the Classic model by incorporating the redesigned alloy trigger housing, AR style magazine and flash suppressor. The SIG 556 Classic brings back the look and feel of one of the world’s most sought after military rifles but on a platform available for law enforcement and responsible citizens
