Proof Research 6.5CM Carbon Fiber 22" AR-10 Barrel 100639

Upgrade your long-range platform with the Proof Research 100639, a premium 22-inch 6.5 Creedmoor carbon fiber-wrapped barrel engineered for match-grade precision. By wrapping a sub-MOA 416R stainless steel core in aerospace-grade carbon fiber, this barrel reduces weight by up to 64% compared to traditional steel contours while drastically improving heat dissipation. It features the proprietary Rifle +2 (CAMGAS) gas system, which optimizes bore pressure timing to deliver a softer recoil impulse, smoother cycling, and cleaner extraction. Threaded in 5/8-24 and built with DPMS-compatible feed ramps, it provides the perfect blend of lightweight mobility and heavy-barrel accuracy for your AR-10 build.
