A Winchester SXP 20GA replacement barrel built for shooters who want a lighter, faster-swinging option for wingshooting or sport shooting. This 26-inch barrel pairs the nimbleness of a 20-gauge with the Super X-Pump platform's smooth, reliable action—ideal when you're running a dedicated 20 on a multi-barrel SXP or upgrading from a heavier tube. The matte black finish resists glare and blends into most hunting and range setups without demanding attention.
The barrel ships with a Modified choke and a brass bead front sight, so you're ready to pattern and shoot straight out of the box. Winchester's Invector-Plus flush-choke system gives you flexibility to swap loads—tighter patterns for ducks, more open spreads for upland birds—without buying a new barrel. At just over 2 pounds, this tube won't tire your swing on a day of repetitive shooting.
Fit and function are guaranteed to the SXP platform: this is a direct swap for any existing Super X-Pump 20-gauge barrel or a way to add 20-gauge capability to an SXP receiver you already own. Steel construction and Winchester's manufacturing standards mean it'll stand up to standard and 3-inch loads for seasons to come.

This barrel is designed exclusively for the Winchester Super X-Pump (SXP) platform in 20-gauge. It will not fit other Winchester models or 12-gauge SXP receivers.
The barrel includes a Modified Invector-Plus flush choke. Because it uses the Invector-Plus system, you can swap in other compatible flush chokes to adjust your pattern for different hunting or shooting scenarios.
Yes. This is a 3-inch-rated barrel and will cycle both standard 2.75-inch and 3-inch 20-gauge ammunition.
This is the barrel only. It will fit directly onto an existing SXP 20-gauge receiver without additional parts or modifications, assuming your receiver is already set up for a 26-inch tube.
