Proof Research Barrel Blank CF PXT .284 24" – Carbon Fiber Wrapped Precision Blank

The Proof Research Barrel Blank CF PXT .284 24" is a carbon fiber-wrapped barrel blank designed for custom rifle builds requiring match-grade accuracy in a lightweight package. Built with Proof's proprietary carbon fiber wrap over a stress-relieved stainless steel core, this blank delivers the rigidity and heat dissipation characteristics serious precision shooters demand. The .284 caliber bore is ideal for cartridges like 7mm-08 Remington, .284 Winchester, and similar chamberings. This is an unfinished blank that requires professional machining, chambering, threading, and fitting by a qualified gunsmith.

The 24-inch length provides flexibility for custom contour profiling and final barrel length selection. The CF PXT (Carbon Fiber Precision X-Treme) construction combines a match-grade stainless steel liner with an aerospace-grade carbon fiber overwrap, resulting in a barrel blank that weighs significantly less than all-steel equivalents while maintaining thermal stability and shot-to-shot consistency. This blank is sold as a raw component for custom rifle projects and includes no additional hardware or chambering.
