BenelliÂs innovative R1 big-game rifle is built around the patented, battle-tested Auto-Regulating Gas-Operated (A.R.G.O.) piston-driven system used in our M4 tactical shotguns. This is the system selected by the U.S. Marine Corps for its relentless reliability, and it reduces felt recoil in our R1 rifles by nearly 50% compared to bolt-action rifles in the same calibers. Combined with our ComforTech® recoil-reduction system (available in synthetic stock models only), the A.R.G.O. system helps tame the flinch factor when shooting large-caliber rifle rounds. An included shim kit lets you customize the fit of the R1.
