Proof Research Tikka T3x Pre-Fit 6mm Creedmoor 24" Sendero Carbon Fiber Barrel, 1:7.5 Twist, 4-Groove, 5/8"-24 Thread

The Proof Research Tikka T3x pre-fit 6mm Creedmoor barrel is a carbon fiber Sendero contour barrel built for hunters and long-range shooters who demand precision without unnecessary weight. This 24-inch barrel ships pre-fitted to Tikka T3x actions, meaning you're skipping the gunsmith and going straight to a ready-to-shoot upgrade. The 1:7.5 twist rate is optimized for 6mm Creedmoor ballistics, handling a wide range of modern match and hunting bullets. Carbon fiber construction keeps the overall rifle light and easy to carry into the field, while maintaining the rigidity needed for consistent accuracy at distance.

The Sendero contour tapers from the action forward, balancing stiffness and weight in a profile proven across countless long-range builds. Your 24-inch length gives you velocity and velocity consistency without the unwieldy balance of a full magnum-length barrel. The 5/8"-24 muzzle thread accommodates industry-standard suppressors and brakes, letting you customize the muzzle end to your setup. Four-groove rifling is standard for modern precision barrels—easier to clean, less copper retention than traditional designs.

Proof Research barrels are made in Montana to tight tolerances and backed by shooters who rely on them for competition and hunting. Drop this into your Tikka T3x and you're looking at a rifle built for 6mm Creedmoor's sweet spot: manageable recoil, flat trajectory, and energy delivery that works from the bench to 1,000 yards and beyond.
