The Winchester Super X4 (SX4) is a top-tier autoloading shotgun renowned for its versatility and cutting-edge design, making it a reliable choice for a range of shooting environments, from the field to the marsh. The Active Valve Gas System is a standout feature, automatically adjusting the gas pressure needed to cycle various loads, from lighter 1 1/8 oz 2 3/4” shells to heavy magnum waterfowl loads, making the SX4 incredibly versatile. Its back-bored technology ensures tighter shot patterns by optimizing the internal barrel diameter, enhancing performance. The Invector-Plus Choke System provides added consistency and easy interchangeability, with standard chokes including full, modified, and improved cylinder tubes for diverse shooting needs. In addition to its superior shooting capabilities, the SX4 boasts enhanced ergonomics with a lighter overall weight and a comfortable close-radius grip, allowing for better handling and target acquisition. The Inflex Technology Recoil Pad and adjustable length of pull spacers further reduce recoil and improve fit for shooters. Other notable features include the chrome-plated chamber and bore, oversized bolt handle and release button, and a spring-loaded ejector for faster, more reliable operation. Available in multiple variants like the SX4 Field, SX4 Compact, and SX4 Defender FDE, the shotgun offers flexibility for different user preferences, from upland hunting to tactical use.
