The Winchester SX4 Waterfowl is a 12 gauge semi-auto shotgun (Winchester part no. 511212292) built for hard hunting in the blind. It pairs a 28-inch steel barrel finished in Mossy Oak Bottomland camo with a matching composite stock, giving waterfowlers a shotgun that all but disappears against marsh cover. The 3.5-inch chamber handles everything from light loads to heavy magnum waterfowl shells, and a chrome-plated chamber and bore stand up to wet, corrosive hunting conditions season after season. Textured grip panels, an Inflex 1 recoil pad, and a fiber optic front sight round out a shotgun built to put birds in the bag.
