The 26″ 20 Gauge SX4 Field is a Beautiful Shotgun with the Handling and Ergonomics You’ve Been Waiting For

The Winchester SX4 is one of the best auto loading shotguns available today, ready to perform like a champion at all times! Its comfortable ergonomics, sleek profile, and rugged reliability are available to you at a price you can afford. Precision manufactured and engineered for endurance the Super X4 will continue to excel shot after shot, round after round. Featuring a 26″ barrel with a chrome-plated bore and chamber, a fiber optic front sight, and Active Valve gas system, the SX4 provides exceptional accuracy. The Active Valve gas operating system automatically adjusts to allow the exact gas pressure necessary to fire a wide range of loads, giving you a greater versatility on the range and in the fields. Improvements over the SX3 include an oversized bolt handle, bolt release, and trigger guard for easier access and operation with gloved hands in cold weather. The Inflex Technology recoil pad has been widened and thickened to further minimize felt recoil, making the SX4 even more comfortable to shoot all day long. A most noticeable change from the SX3 is the reduced weight and ideal placement of the balance point with a narrower pistol grip. These seemingly small changes greatly improve the swing and point of the shotgun, enabling you to get on target faster and more accurately. Lighting-fast operation, lightweight design, and proven reliability, makes the Winchester SX4 Field a great choice for both the hunter and sporting clay shooter.
