Thompson Center Arms 8340R Encore 450 Bushmaster 26" Silver S/S Brl

The Thompson Center Encore 450 Bushmaster barrel is a stainless steel replacement barrel built for shooters who want to expand their Encore rifle's capability without investing in a whole new gun. At 26 inches long, this barrel gives you the reach and velocity the 450 Bushmaster cartridge was designed to deliver, whether you're hunting medium to large game or pushing distance on the range. Thompson Center's Pro Hunter barrels are factory test-fired at 100 yards to confirm accuracy before they leave the shop, so you're starting with a known-good platform.

Constructed from stainless steel, this barrel resists corrosion and weather—a real asset if you hunt wet country or store your rifle in less-than-ideal conditions. The fluting isn't just for looks; it's engineered to maximize strength while keeping weight down, so you get a rigid barrel that won't slow you down in the field. Switching barrels on an Encore requires no gunsmithing. If you own an Encore frame, you can swap calibers and barrel lengths in minutes, making it one of the most versatile platforms available to hunters and shooters.

This barrel is sized specifically for Thompson Center Encore rifles. It will not fit Contender or G2 Contender frames, so verify your rifle platform before ordering. The 5/8-24 thread pattern is standard for Encore barrels, ensuring a secure fit to your action.
