It uses billet upper and lower receivers and a rifle-length gas system. An RRA Operator Brake on the 5/8-24 muzzle thread helps tame recoil, and a 17-inch lightweight free-float rail with M-LOK compatibility holds accessories. A 6-position Operator CAR stock and a Hogue rubber grip finish the build. It is a flat-shooting rifle for hunting and precision work from Rock River Arms.
