Proof Research Bbl Cf Bolt Blank 24 6.5Prc 1-7.5 5/8-24 Carbon Fiber

The Proof Research PROOF BBL CF BOLT BLANK 6.5PRC 24 BIGHORN 1-7.5 blends advanced carbon fiber engineering with proven precision rifle components to deliver a lightweight, rigid platform for long-range performance. Built around a 6.5 PRC cartridge, this 24-inch barrel features a 1-7.5 twist and a 5/8-24 muzzle thread, optimized for stability with modern long-range projectiles while maintaining excellent handling characteristics for field or bench use. The Sendero-contour profile provides a balance of stiffness and weight, and the carbon fiber finish reduces overall weight to a practical 3 lbs with the barrel itself weighing around 2.15 lbs, enabling quicker target reacquisitions and smoother swing during rapid shot sequences. Designed for demanding shooters, this barrel blank combines Proof Researchs signature rigidity with a lightweight, corrosion-resistant carbon fiber exterior to improve heat management and consistency under extended strings. Ideal for precision rifle builds, competition settings, and high-accuracy field rifles, it supports tight groupings, predictable windage, and repeatable returns to target, making it a trusted choice for serious PRC enthusiasts seeking reliable performance from a compact, high-strength barrel system.
