PROOF Research PXT Carbon Fiber Barrel Blank .264 18" 1:7.5 Sendero Light

The PROOF Research PXT Carbon Fiber Barrel Blank is a premium .264-caliber bolt-action barrel blank designed for lightweight custom precision and hunting rifle builds. This configuration features an 18-inch length, 1:7.5 twist rate, 5-groove PXT rifling, carbon fiber construction, and Sendero Light contour, creating a compact barrel platform focused on reduced weight, rigidity, and precision performance.

PROOF Research's advanced carbon fiber barrel construction combines a precision steel barrel core with aerospace-grade carbon fiber to reduce overall weight while maintaining the rigidity expected from a performance-oriented rifle barrel. The Sendero Light contour provides a balance between weight savings and barrel stiffness, while the compact 18-inch length is particularly well suited to maneuverable custom rifle configurations.

The fast 1:7.5 twist rate and 5-groove PXT rifling provide a modern bore configuration for compatible .264-caliber/6.5mm projectiles. As an unfinished barrel blank rather than a chambered pre-fit or drop-in barrel, this product provides the flexibility for cartridge-specific chambering, threading, headspacing, and action-specific fitting during the custom rifle build.
