Utilizing PXT (PROOF Exponential Twist) geometry, this barrel features a redesigned rifling twist progression and reduced lead angle designed to minimize engraving force, decrease throat erosion, and smooth projectile engagement. This technology extends barrel life by 30% to 100% while reducing felt torque for improved recoil management and target retention. Wrapped in high-strength, aerospace-grade carbon fiber infused with a proprietary matrix resin over a precision core, the barrel offers extreme temperature resistance, superior heat dissipation, and a weight savings of up to 64% compared to traditional steel contours. It comes chambered in 300 PRC with a 24-inch length, a 1:9 twist rate, and a Sendero contour, arriving fully threaded and chambered for direct installation on compatible actions.
