From running a 3-gun competition course to hunting turkey or simply keeping it handy while camping in the woods, the SX4 Extreme Defender shotgun excels in versatility. Like all SX4 models, this autoloader is powered by the highly reliable Active Valve Gas System, providing exceptional performance across a wide range of loads with impressive cycling speed. The compact 18-1/2 inches barrel makes it easy-to maneuver through brush and obstacles at the range. The Invector-Plus interchangeable choke tube system offers the flexibility to achieve a dense pattern at the desired distance. For added comfort, the pistol grip stock ensures an easy reach to the trigger, while the raised comb aligns your eye perfectly with the ghost-ring style LPA rear sight.
