Proof Research Carbon Fiber Barrel Blank – .284 Caliber, 20 Inches

The Proof Research Carbon Fiber Barrel Blank in .284 caliber delivers match-grade accuracy with significant weight savings over traditional steel barrels. Constructed with a proprietary carbon fiber wrap around a precision-machined stainless steel core, this blank provides the stiffness and heat dissipation needed for consistent shot-to-shot performance without the barrel whip common in lightweight profiles.

This 20-inch blank is designed for custom rifle builds and professional gunsmithing work. It arrives unfinished and unthreaded, ready for chambering, contouring, and threading to your specifications. The carbon fiber construction reduces overall rifle weight while maintaining the rigidity required for precision shooting applications.
