Proof Research Pre-Fit Barrel Features The Proof Research Pre-Fit Barrel for the Tikka T3X combines match-grade accuracy with a dramatic reduction in weight thanks to its carbon fiber wrapped construction. This design improves heat dissipation for cooler running and longer lasting barrels helping prevent point-of-impact shift during high-volume strings of fire. Reduced harmonic barrel vibration also contributes to tighter more repeatable groups at distance. The 22 inch Sendero contour and 1:7.5 inch twist rate are matched well to the heavier bullet weights commonly used in 6.5 PRC long-range loads. Finished in a stainless steel interior with the signature Proof carbon fiber exterior wrap the barrel resists weather nicks dings and scratches far better than a traditional steel barrel. A 5/8x24 thread pattern allows direct mounting of a suppressor or muzzle brake once the barrel is threaded and chambered by a gunsmith. At 2 pounds 10 ounces the barrel is up to 64 percent lighter than comparable steel options making a noticeable difference in a rifle s balance and carry weight. The Proof Research Pre-Fit Barrel gives Tikka T3X owners a serious accuracy and weight upgrade in 6.5 PRC.
