Winchester Guns Sx4 Wgun 511289392 Sx4 Wtfwl 12 3 28 Wdlnd

The Winchester SX4 Waterfowl Hunter is a 12-gauge autoloading shotgun built for serious waterfowl hunters who demand reliable performance in tough conditions. This semi-auto shotgun pairs Winchester's proven Active Valve gas system with a lightweight aluminum receiver and woodland camouflage finish—a time-tested concealment pattern that works across flooded timber, marshes, and cattail-heavy wetlands. The 28-inch barrel features a chrome-plated chamber and bore to stand up to steel shot and salt-air abuse, plus a ventilated rib for improved sight picture. If you're running a traditional waterfowl rig that cycles soft and fast without the fuss, the SX4 delivers the speed and shootability waterfowlers expect.

Winchester engineered the SX4 to improve on the legendary SX3 platform by refining balance, internal components, and shooter ergonomics. The larger bolt handle and bolt release make operation smoother in cold conditions or heavy gloves, while the reversible safety button lets you set it up for your preferred hand. The new Inflex Technology recoil pad reduces felt recoil, which matters when you're shooting shells all day. You get three Invector-Plus choke tubes (Full, Modified, and Improved Cylinder), a fiber-optic front sight for low-light mornings, and sling swivel studs for secure carry.

The SX4 accepts both 3-inch and 3½-inch magnum loads, giving you flexibility in your ammo choice without swapping shotguns. Composite stock and foregrip in woodland camo round out the package—no exposed wood to soak up water or slow you down. Whether you're a duck devotee or a goose specialist, this is a shotgun that handles the recoil, tracks birds cleanly, and stays concealed when it counts.
