The Thompson Center Encore ProHunter Katahdin rifle barrel in .450 Bushmaster gives you serious flexibility in your Encore platform firearm. This 20-inch stainless barrel is threaded at 11/16-24, letting you run a suppressor or muzzle device that fits your shooting style. The .450 Bushmaster cartridge delivers power for medium to large game without requiring a magnum platform—it's the kind of caliber swap that turns one Encore receiver into a multi-purpose hunting tool.
If you already own an Encore rifle, this barrel opens up a new hunting season or game pursuit without buying an entirely new firearm. The stainless construction handles weather and repeated use in demanding conditions, and the threaded muzzle means you can tailor your setup to your hunting situation. Whether you're hunting from a stand, hiking to a glassing point, or working timber where follow-up shots matter, the .450 Bushmaster in this configuration gives you options.
Thompson Center's interchangeable barrel system is built on decades of American gunmaking expertise. You're not locked into one caliber or one season—swap this barrel onto your Encore receiver and you're ready for a completely different hunt. The 20-inch length balances velocity with handling in typical hunting scenarios, and stainless steel means it'll hold up whether you're hunting in wet New England valleys or dry Western canyons.
