The PROOF Research PXT .308 Carbon Fiber Barrel Blank combines advanced rifling technology with the lightweight performance and precision that PROOF barrels are known for. Featuring the innovative PXT (PROOF Exponential Twist) design, this barrel blank offers a reimagined rifling geometry and twist progression. This engineering reduces engraving force, minimizes throat erosion, and ensures a smoother transition as the projectile engages the rifling.

The PXT technology significantly reduces wear, improves consistency, and lessens felt torque during firing, enhancing recoil control and target retention. Controlled tests have shown a 30-100% increase in barrel life while maintaining the accuracy expected from PROOF barrels. Built with carbon fiber construction, this barrel blank offers exceptional stiffness-to-weight ratio, reducing overall rifle weight without sacrificing performance.

Ideal for custom rifle builders and gunsmiths, the PROOF PXT .308 barrel blank is a premium choice for lightweight hunting rifles, precision long-range systems, and modern high-performance rifle builds.
