Overview
From running a 3-gun competition course to hunting turkey or just keeping handy when camping in the woods, the biggest feature of a Winchester SX4 Defender shotgun is versatility.

Like all SX4 models, these autoloaders are powered by the ever reliable Active Valve Gas System that offers superior reliability with a wide range of loads and impressive cycling speed. The compact, 18-1/2" barrel is easy to maneuver in the brush and through range obstacles. The Invector-Plus interchangeable choke tube system gives the versatility needed for a dense pattern at distance required. Built for durability, the composite stock features textured grip surfaces for added security in all conditions.
