The Blaser R8 Replacement Barrel in 7mm PRC optimizes modern, long-range performance inside a lightweight, highly maneuverable configuration. Engineered with a fast 1:8" twist rate, it perfectly stabilizes heavy, high-ballistic coefficient modern projectiles downrange. The 17mm standard profile features precision longitudinal fluting that decreases overall weight while rapidly expanding the outer surface area for enhanced thermal dissipation. Concentric factory-cut M15x1 muzzle threading is machined at the crown to host direct-thread suppressors or recoil-reducing muzzle brakes. Incorporating the proprietary R8 locking lug layout, it locks rigidly into your modular receiver to guarantee an absolute return-to-zero point of impact upon installation.
