The Winchester SX4 Hybrid (brand part no. 511251391) is a 12-gauge semi-auto shotgun built on Winchester’s Active Valve gas system, finished head to toe in Gray Cerakote for a distinctive, corrosion-resistant look. Winchester chambers the SX4 Hybrid for 3-inch shells behind a 26-inch, chrome-plated vent rib barrel, and includes three Invector-Plus choke tubes (Full, Modified, Improved Cylinder) for hunting or clays. A TruGlo fiber-optic front sight, Inflex Technology recoil pad, and a reversible safety button round out a shotgun built for fast target acquisition and comfortable follow-up shots.
