Winchester Super X4 Barrel Features This Winchester replacement barrel is built to fit the Super X4 a 20 gauge 3 inch chambered 22 inch rifled barrel designed specifically to maximize accuracy with 2.75 and 3 inch sabots and slugs. The fully rifled bore imparts spin to the slug for improved stability and accuracy compared to a smoothbore barrel making it a purpose-built option for deer hunters who want tighter groups at typical slug-gun ranges. A Weaver-style cantilever rail is built onto the barrel itself allowing a scope to be mounted directly to the barrel rather than the receiver so zero is retained even if the barrel is swapped back out. The traditional matte blued finish protects the steel barrel from the elements while keeping a classic low-glare appearance in the field. Sighting is handled by a TruGlo fiber optic front sight paired with a folding adjustable rear sight giving the shooter a fast precise aiming reference for those who prefer iron sights over an optic. The barrel includes an extra forend finished in black synthetic to match the deer barrel setup giving the shotgun a distinct look when configured for slug hunting. Swapping barrels lets a Super X4 owner move between waterfowl or upland hunting in one configuration and dedicated deer slug hunting in another all without the cost of a second complete shotgun. Built to the same factory quality and precision as the original equipment barrel the Winchester Super X4 rifled cantilever barrel is available for sale at GrabAGun.
