From the reliable gas operating system to the rugged black composite stock and forearm to the low luster finish on exposed metal surfaces, the 3" Super X2 Composite is pure utility. The simple gas-operated action allows you to shoot the heaviest factory 3" magnums, light 2 3/4" (1 oz.) field loads and everything in between. The gas operation also reduces recoil and allows for unbelievably fast follow-up shots. Sling swivel studs included.
