Proof Research PXT Carbon Fiber Barrel Blank 264 Caliber 24" Sendero Contour Light 1:7.5" Twist 5 Groove

Overview

The PROOF Research PXT Carbon Fiber Barrel Blank is engineered for .264 caliber rifle builds, featuring a 24-inch length, Sendero contour light profile, and a 1:7.5" twist with a 5-groove configuration. Utilizing PROOF Exponential Twist (PXT) geometry, this barrel blank features a revised rifling twist progression and reduced lead angle designed to lower engraving force, minimize throat erosion, and smooth projectile engagement for improved consistency, recoil control, and an extended barrel life of 30% to 100%. Wrapped in aerospace-grade carbon fiber impregnated with a proprietary matrix resin over a steel core, this barrel blank provides an exceptional stiffness-to-weight ratio. It offers up to 64% weight reduction compared to traditional steel barrels of a similar contour while delivering superior heat dissipation and extreme temperature resistance for precision long-range and lightweight hunting rifle builds.
