This Proof Research pre-fit barrel is made for the Tikka T3X, giving T3X owners a 24.00" .300 Win Mag barrel in a carbon fiber wrapped Sendero contour. A pre-fit barrel is chambered for its specific action, so it arrives ready to install on the T3X, and the 5/8x24 threaded muzzle accepts a brake or suppressor.
PXT is Proof's Exponential Twist rifling, a rework of conventional rifling geometry and twist progression that lowers engraving force, reduces throat erosion and eases the bullet's entry into the rifling. The 24.00" length gives .300 Win Mag the barrel it needs to burn a full magnum powder charge, making the T3X a flat-shooting rifle for long-range elk and open-country hunting.
