The legendary performance and accuracy of the Swiss-built SG 550 tactical rifle is found in every SIG556 Classic. The Classic SWAT is a semiautomatic 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 SWAT features a Swiss-type folding stock, as well as a aluminum quadrail forend that is ideally suited for mounting accessories. The Classic SWAT’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. sig 556 swat
