Winchester's legendary SX4 waterfowl shotgun delivers proven Active Valve gas operation in a 20-gauge, 28-inch configuration with Mossy Oak Shadow Grass camouflage and three Invector choke tubes.
The Winchester SX4 represents the pinnacle of modern waterfowl shotgun design, purpose-built for the demanding conditions of the marsh and wetlands.
At the heart of the SX4 lies Winchester's legendary Active Valve gas operating system—the same technology that earned its reputation through generations of the SX3 and SX2 platforms. This system has been extensively tested, refined, and perfected to deliver the reliability that serious waterfowlers demand. The Active Valve design cycles reliably across a wide range of ammunition loads, from light target rounds to heavy magnum waterfowl loads.
The 20-gauge platform offers a significant advantage for waterfowlers who value reduced recoil without sacrificing effective range. This shotgun handles the punishment of extended hunting seasons while maintaining the accuracy and pattern consistency that separate successful hunts from empty shells. The included choke tube system provides flexibility for varying distances and conditions throughout the season.
