Winchester SPX Defender 20 Gauge 18″ 5 1



The Winchester SPX Defender 20 Gauge pump action shotgun lives up to its name with an 18″ fixed cylinder choked barrel that allows for the use of slugs and delivers a wide pattern with buckshot. A traditional brass bead front sight provides a fast and accurate sight picture while a ribbed forearm and synthetic stock with textured gripping surfaces provide firm control even under stress. The receiver is drilled and tapped for scope bases. A hard chrome plated chamber and bore protects against internal corrosion and wear. Non-glare metal surfaces and durable black composite furniture provide external protection from corrosion and hard use. This reliable pump action shotgun is compact enough to use in tight quarters and easy to operate. The Defender’s cross bolt safety is easy to operate and the Inflex Technology recoil pad directs recoil down and away from your cheek to reduce flinch and fatigue. The Winchester SPX Defender 20 is the perfect choice for home defense. Its inertia-assisted action, six-shell total ammo capacity, durable composite stock and ribbed forearm give you an edge against any odds.
