PROOF Research PXT Carbon Fiber Barrel Blank .308 18" 1:10 Twist Sendero

PROOF Research PXT Carbon Fiber Barrel Blank .308 18" 1:10 Twist Sendero

The PROOF Research PXT Carbon Fiber Barrel Blank is a premium bolt-action barrel blank designed for custom precision rifle builds. This configuration features a .308 caliber bore, 18-inch length, 1:10 twist rate, 5-groove PXT rifling, carbon fiber construction, and Sendero contour, providing a lightweight and rigid foundation for a professionally fitted custom rifle barrel.

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 and performance characteristics expected from a substantial barrel profile. The Sendero contour provides a precision-oriented configuration, while the compact 18-inch length is well suited to custom builds where maneuverability and reduced overall weight are priorities.

The 1:10 twist rate and 5-groove PXT rifling provide a precision-focused bore configuration for compatible .308-caliber projectiles. As a barrel blank rather than a pre-fit or drop-in barrel, this product requires final chambering, threading, headspacing, and fitting for the intended cartridge and action by a qualified gunsmith.
