2024 SHOT Show Special – Versatile semi-automatic shotgun with synthetic pistol grip stock in Woodland camouflage. LPA front sight and rear ghost ring sight mounted on a Picatinny rail. Active Valve gas operation. Invector-Plus choke tubes.


From running a 3-gun competition course to hunting turkey to just keeping handy when camping in the woods, the biggest feature of the SX4 Extreme 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. If you’re looking for comfort, the pistol grip stock offers an easy reach to the trigger while the raised comb puts the eye in perfect alignment with the ghost-ring style LPA rear sight.
