PROOF Research PXT Carbon Fiber Barrel Blank .308 20" 1:10 Sendero

The PROOF Research PXT Carbon Fiber Barrel Blank is a premium .308-caliber bolt-action barrel blank designed for custom precision and hunting rifle builds. This configuration features a 20-inch length, 1:10 twist rate, 5-groove PXT rifling, carbon fiber construction, and Sendero contour, providing a versatile foundation for a lightweight, performance-oriented custom rifle.

PROOF Research’s advanced carbon fiber barrel construction combines a precision steel barrel core with carbon fiber technology to reduce overall weight while maintaining the rigidity and thermal stability expected from a precision barrel. The Sendero contour provides a substantial profile for increased stiffness, while the 20-inch length offers a balance of compact handling and barrel length for a variety of custom applications.

The 1:10 twist rate and 5-groove PXT rifling provide a precision-focused bore configuration for compatible .308-caliber projectiles. Because this is an unfinished barrel blank rather than a chambered pre-fit or drop-in barrel, final chambering, threading, headspacing, and action-specific fitting are required, allowing the barrel to be tailored to the intended cartridge and bolt-action rifle build.
