The Proof Research PR10 6.5 Creedmoor Carbon Fiber CamGas AR-10 Barrel, 24" Threaded, Stainless/Carbon Fiber, is built for shooters who demand match-grade precision in a lighter, stiffer package. Starting with a full-profile 416R stainless steel blank that is turned down and then wrapped in aerospace-grade carbon fiber, this 24" heavy-profile barrel delivers excellent rigidity, heat management, and consistency while significantly reducing weight compared to traditional steel barrels.

Optimized for the 6.5 Creedmoor cartridge and AR-10 / LR-308 platforms, the PR10 CamGas barrel uses a rifle +2 length gas system, a 0.875" gas block journal, and a 1:8 twist to stabilize a wide range of bullets for long-range target shooting and precision competition. The 5/8x24 threaded muzzle makes it easy to add brakes or suppressors, and the deep-feed design enhances reliable cycling over extended range sessions. Proof Research’s focus on advanced materials and meticulous craftsmanship results in a barrel that offers repeatable accuracy and long-term durability.
