Thompson Center Encore ProHunter Barrel Features The Thompson Center Encore ProHunter Barrel is machined from stainless steel with a 1:16 twist rate tuned specifically to stabilize .450 Bushmaster projectiles for reliable terminal performance on deer and hog-sized game. Spiral fluting removes excess material along the barrel s length cutting overall weight without sacrificing the rigidity needed for consistent accuracy shot after shot. Every ProHunter barrel is test fired at the factory at 100 yards so hunters can trust the accuracy potential straight out of the box with no additional break-in required. The 5/8x24 threaded muzzle accepts a wide range of aftermarket brakes compensators and suppressors for shooters who want to further tailor recoil management. This barrel installs on Encore series frames only and Thompson/Center notes it will not fit Contender or G2 Contender receivers so Encore owners can swap calibers without gunsmithing. The stainless steel finish resists corrosion in wet hunting conditions and pairs a weather-hardy exterior with the same accuracy-focused engineering found across the Encore lineup. Because no fitting is required shooters can move between calibers in minutes simply by swapping barrels on their existing frame. This ProHunter barrel gives Encore owners an affordable path to adding the .450 Bushmaster cartridge to their hunting arsenal.
