The Proof Research PXT Pre-Fit Barrel for the Tikka T3x (brand part no. 152645) pairs Proof’s carbon-fiber-wrapped construction with PXT — Proof Exponential Twist — rifling in a 22-inch 7mm PRC configuration. Proof Research wraps a match-grade core in aerospace-grade carbon fiber for a barrel up to 64 percent lighter than a comparable steel contour, with improved heat dissipation and the stiffness-to-weight ratio that made Proof’s reputation. The PXT rifling geometry reduces engraving force and throat erosion for longer barrel life and smoother projectile engagement. As a pre-fit, it is machined for the Tikka T3/T3x action pattern. Among rifle barrels, this PXT pre-fit favors long-range hunters rebarreling a T3x to the flat-shooting 7mm PRC.
