Thompson Center Encore ProHunter Katahdin Barrel Features The Thompson Center Encore ProHunter Katahdin Barrel lets an existing Encore frame owner add a new caliber option without buying an entirely new rifle reflecting the Encore system s core swap-barrel philosophy. Chambered in .400 Legend with a 1:16 inch twist rate the barrel is tuned to stabilize projectiles suited to the cartridge s hunting applications. Fluting along the barrel reduces weight while helping to dissipate heat faster than a solid contour which matters when carrying the rifle through a long day afield. Every Pro Hunter barrel undergoes factory test firing at 100 yards to confirm it meets accuracy standards before it reaches the customer. A matte blued finish on the barrel resists the elements while giving it a traditional look that matches Thompson Center s existing Encore lineup. The barrel is drilled and tapped for scope mounts right out of the box so no gunsmithing is required to add an optic once installed on the frame. A 5/8x24 thread pattern at the muzzle accepts a brake for recoil management or a suppressor for hunters who want a quieter shot. This barrel fits Encore series rifles exclusively and will not fit Contender or G2 Contender frames so Encore owners can add a dedicated .400 Legend option available for sale at GrabAGun.
