WGUN 511332292 SX4 LH WTFL MOOSG,12-3.5,28 INV+

The Winchester Super X4 Left-Hand Waterfowl with Mossberg choke configuration, 12-gauge, 3.5-inch chamber, 28-inch barrel is a purpose-built autoloader engineered for demanding marsh conditions. Built on Winchester's Active Valve gas operating system—the same proven platform that anchored the SX3 and SX2—this left-hand shotgun combines field-tested reliability with the ballistic capacity serious waterfowlers demand. The 3.5-inch chamber enables heavier shot payloads and extended range, critical advantages when working over open water or in high-wind situations where standard 2.75-inch loads fall short.

The 28-inch barrel balances velocity and handling—long enough to optimize shot performance from 3.5-inch magnum loads, yet manageable in close quarters or from a boat. The Active Valve system cycles reliably across shot weights, from light target loads to maximum magnum rounds, reducing short-stroking and eliminating the adjustments required by traditional gas systems. Included are three Invector choke tubes—full, modified, and improved cylinder—allowing field adjustment for varying distances, decoy spreads, and weather conditions. Sling swivel studs are factory-installed for quick attachment of traditional waterfowling harnesses. The left-hand design accommodates southpaw shooters with traditional controls, eliminating safety-check fumbling and ejection interference.

This platform is ideal for dedicated waterfowlers who operate in corrosive salt-air environments and need an autoloader that functions flawlessly across extended seasons. The SX4 is trusted by hunters who prioritize consistency—those who count on their shotgun to perform when decoying mallards at dawn or swinging on high passing flocks. Operators seeking a left-hand waterfowl autoloader with proven reliability and factory choke versatility will find the Winchester Super X4 a validated choice backed by generations of field performance.
