The Winchester SX4 Waterfowl Hunter is a 12-gauge semi-automatic shotgun purpose-built for duck and goose hunting. Built on the proven SX3 platform, this 26-inch-barrel gun combines Winchester's gas-operated Active Valve system with the iconic Mossy Oak Bottomlands camouflage finish—a pattern waterfowl hunters have trusted for generations. Whether you're working a marsh blind or a river bend, the SX4 delivers reliable cycling and a balanced handling profile that won't wear you out over a long season.
Winchester refined the SX4 with thoughtful upgrades for the field. The enlarged cocking handle and bolt release let you work the gun smoothly even with heavy gloves, while the reversible safety button means you can configure it for your hand preference. A wider trigger guard opening accommodates a gloved finger comfortably. The new Inflex recoil pad reduces felt kick, and adjustable length-of-pull spacers let you dial in a proper fit. All of that adds up to a gun that points naturally and cycles reliably when conditions get messy.
You get three Invector-Plus choke tubes so you can match your pattern to distance and conditions. The chrome-plated chamber and bore resist corrosion—essential when you're around water and salt spray. A fiber-optic sight aids target acquisition in low light, and sling swivel studs are already installed. The 3-inch chamber handles both standard and magnum loads, giving you flexibility in ammunition selection for different waterfowl scenarios.
