Thompson Center Encore Prohunter Shotgun Barrel 20 ga 3" Chamber 26" Stainless

The Thompson Center Encore Prohunter shotgun barrel in 20 gauge gives you the flexibility to hunt waterfowl, upland birds, and small game with the modularity the Encore platform is built for. This 26-inch stainless barrel with a 3-inch chamber lets you reload your Encore rifle or muzzleloader frame with a dedicated shotgun setup, turning a single firearm into a multi-season hunter. If you already own an Encore rifle or muzzleloader, swapping to this barrel means you're not locked into one caliber or one type of game—you can pursue nearly any opportunity across North America without buying a second gun.

The 20 gauge is a natural fit for hunters who want less recoil than a 12 gauge without sacrificing pattern and range on birds and small game. The 3-inch chamber accepts both 2.75-inch and 3-inch loads, giving you flexibility in ammunition selection. Stainless steel construction resists corrosion and weathering, critical when you're working a barrel that might spend time in brush, rain, or salt air.

This is the Encore's core value proposition: own one frame, own multiple barrels, own multiple hunting seasons. Whether you're building your first Encore shotgun setup or adding another barrel to an existing rifle or muzzleloader frame, this 20 gauge barrel expands what your gun can do.
