The Winchester SX4 NWTF Cantilever Turkey 20-gauge is a dedicated turkey hunting shotgun built on the proven SX4 semi-automatic platform and co-developed with the National Wild Turkey Federation. Chambered in 20 gauge with a 24-inch barrel, this compact turkey gun delivers the maneuverability you need in tight brush while maintaining the reliability that Winchester's Active Valve system is known for. The 20-gauge round pairs lighter recoil with real knockdown power—ideal for hunters who want to stay sharp through a long spring season.
From the receiver to the muzzle, every detail serves turkey hunting. The hard chrome-plated chamber and bore stand up to repeated shooting and the weather that comes with spending dawn-to-dusk in the field. Back-bored technology ensures your shot pattern stays dense and even at distance. An Invector-Plus extra-full turkey choke is included and fitted with a camo front band. The 24-inch barrel swings fast when a gobbler hangs up in thick timber, and the Mossy Oak Obsession camo finish blends you into spring woods. Adjustable rifle-style sights with a TRUGLO fiber-optic front post let you make clean, quick sight pictures—but the real difference is the Weaver-style cantilever rail. Mount a red dot, electronic sight, or conventional scope without drilling; turkey hunting optics are becoming standard for a reason.
The SX4's synthetic stock is textured for a secure grip in wet conditions, and spacers let you dial in the perfect length of pull. Inflex recoil pad technology angles felt recoil away from your cheek to reduce flinch and fatigue over a long hunt. An ambidextrous crossbolt safety is quick to manipulate from either shoulder, and the drop-out trigger group makes cleaning simple. Winchester backs this partnership with the NWTF—a portion of each sale supports habitat conservation and wild turkey restoration across the nation.
