Proof Research PXT Bolt Action Carbon Fiber Barrel Blank 308

Description

PROOF Research PXT carbon fiber barrel blanks combine next-generation rifling technology with the lightweight performance and precision that have defined PROOF barrels for years. PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling.

By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved recoil control and the ability to stay on target more effectively.

In controlled testing, PXT barrels have demonstrated 30-100% increase in barrel life while maintaining the accuracy standards expected from a PROOF barrel.

Built around Proof Research's proven carbon fiber construction, PXT barrel blanks provide exceptional stiffness-to-weight ratio and reduced overall rifle weight without sacrificing performance. Designed for custom rifle builders and gunsmiths, these blanks offer a premium foundation for lightweight hunting rifles, precision long-range systems, and modern high-performance rifle builds where consistency and durability matter most.

*Note: PXT® barrels require specific attention when machining the muzzle. The crown must be cut at the designated witness ring (+/– .100?). Do not shorten the barrel beyond this point, as doing so may compromise the performance and integrity of the barrel. Please reference the photo below for proper location and alignment. Land width at bore diameter is much more narrow than conventional lands. Please be aware of this if using range rods for bore alignment.
