PROOF Research PXT Carbon Fiber Barrel Blank .224 18" 1:8 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 .224 caliber bore, 18-inch length, 1:8 twist rate, 5-groove PXT rifling, carbon fiber construction, and Sendero contour, providing a lightweight yet rigid foundation for a professionally fitted custom barrel.

PROOF Research's carbon fiber barrel technology combines a precision steel barrel core with advanced carbon fiber construction to reduce overall weight while maintaining the rigidity expected from a substantial barrel profile. The Sendero contour provides a robust precision-oriented profile, while the shorter 18-inch length makes this blank particularly suitable for compact custom rifle configurations where weight and maneuverability are priorities.

The 1:8 twist rate and 5-groove PXT rifling provide a precision-focused bore configuration for compatible .224-caliber projectiles. Because this product is a barrel blank rather than a pre-fit or drop-in barrel, final chambering, threading, headspacing, and fitting must be completed for the intended action and cartridge by a qualified gunsmith.
