The Proof Research 106228 Carbon Fiber Barrel Blank in .284 caliber gives custom rifle builders a lightweight, rigid foundation for precision performance. This 22" Sendero Light contour barrel uses a stainless steel core wrapped in aerospace-grade carbon fiber, balancing reduced weight with the stiffness needed for consistent long-range accuracy and stable harmonics.

As a true barrel blank, it arrives unchambered and unthreaded so your gunsmith can tailor it to your preferred action, cartridge, and muzzle configuration. The 1:8 twist and rifled bore are optimized for a wide range of .284 projectiles, while the carbon fiber wrap promotes faster heat dissipation during extended strings of fire. Ideal for precision rifle builds, competition, and demanding hunting applications, this barrel reflects Proof Research’s focus on advanced materials and repeatable accuracy.
