The Proof Research Carbon Fiber Barrel in 7mm PRC (brand part number 134832) is a direct-fit replacement barrel built for the Tikka T3x action, measuring 24 inches in a Sendero contour and threaded 5/8-24 at the muzzle for a brake or suppressor. Like the rest of Proof’s carbon-fiber lineup, it wraps a reduced-profile stainless steel core in aerospace-grade carbon fiber, cutting weight substantially compared to an equivalent all-steel barrel while holding match-grade accuracy. The barrel is cut with a 1:8 twist to stabilize heavier 7mm PRC bullets, and the finished assembly weighs 2 pounds, 13 ounces, a meaningful savings for a long-range hunting or precision build carried in the field.
