The Winchester SX3 12-gauge barrel is a drop-in replacement or upgrade component for shooters running the Super X3 platform. This 24-inch barrel pairs a matte blued finish with a Modified choke and the versatile Invector-Plus flush system, giving you the flexibility to swap chokes for different hunting scenarios without buying a whole new gun. At just over 2 pounds, it's built on steel for reliability in the field, whether you're working waterfowl, upland game, or clay shooting.
The brass bead front sight keeps your sight picture simple and fast—no rear sight means a clean receiver top and minimal snag risk in brush or from a sling. The 3-inch chamber handles standard and magnum loads, so you're not locked into one type of ammunition. If you already own an SX3 or are building one out, this barrel gives you a compact, handy platform without the weight penalty of longer tubes.
Winchester's Invector-Plus system is one of the most common and affordable choke ecosystems in shotgunning, meaning you'll have no trouble sourcing extra constrictions down the road. The matte finish resists glare and plays well with optics if you ever mount a rail.

The 3-inch chamber accepts both standard 2¾-inch and 3-inch magnum loads.
