Proof Research’s patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks made in their firearms division, then turned down to a significantly reduced profile and wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by Proof Research ACD. The aerospace-grade carbon fiber used is 10 times stronger than stainless steel and has a specific stiffness nearly 6 times greater than steel. This construction delivers barrels up to 64% lighter than traditional steel barrels with improved heat dissipation for cooler and longer lasting performance.
The Proof Research Tikka T3x 7 PRC 22″ 1-8 twist carbon fiber barrel is a Sendero contour, threaded 5/8-24, pre-fit barrel designed specifically for Tikka T3x actions. These pre-fit Tikka T3X shouldered barrels are easy to install with no gunsmith required—just thread it on, torque it down, check head space, and head for the range. The 7mm PRC chambering delivers effective performance for long-range applications, combining flat trajectory and excellent downrange energy retention.
