THE LEGEND CONTINUES, 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’’ chrome lined 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 SWAT is available for law enforcement and responsible citizens. Obtaining a sight picture with the SIG556 SWAT model now takes place using a new rear rotary diopter sight, utilizing aperture calibrations from close quarter ranges out to 100m, 200m, and 300m.
