The Winchester SX4 20-gauge shotgun barrel with cantilever mount is a dedicated turkey and small-game hunting solution built for shooters who want to mount optics on their semi-auto. This 24-inch barrel comes ready to shoot with a factory-installed TruGlo fiber-optic front sight and folding adjustable rear sight, so you can pick up your target fast in low light. The cantilever scope rail lets you bolt on a red-dot or low-power optic without gunsmithing, giving you the flexibility to hunt turkey one season and switch to rifled slugs the next without removing your glass.
Winchester equipped this barrel with the Invector-Plus choke system and includes an Extra-Full extended choke tube, the go-to constriction for turkey loads. The matte blued steel finish won't spook birds and handles the outdoor weather you'll throw at it. At just 2 lbs 12 oz, the barrel maintains the SX4's reputation for handling like a much lighter gun, which matters when you're hiking to your setup before dawn. Drop it onto your Super X4 receiver and you're ready to pattern loads and dial in your optic.
If you already own an SX4 and want to add a dedicated turkey or slug barrel to your setup, this cantilever option gives you serious versatility without buying another gun. The fiber-optic sight still works great in a pinch, and the rail gives you optical precision when conditions demand it. Winchester built this barrel to handle the recoil and shot strings of a semi-auto, so it won't rattle or shift on your gun.
