PROOF 155097 BOLT 264 26 7.5TW PXT

PROOF Research PXT Bolt-Action Barrel Blanks combine next-generation rifling technology with excellent accuracy and durability. The PXT (PROOF Exponential Twist) design reduces engraving force, minimizes throat erosion, and creates a smoother transition for the bullet into the rifling. This technology significantly increases barrel life by 30-100% while maintaining accuracy standards. The barrel is constructed of stainless steel and wrapped with aerospace-grade carbon fiber for lightweight and extreme temperature resistance. It is ideal for custom rifle builders and precision long-range shooting enthusiasts.
