The Benelli M1014 has been in service with the Marine Corps for almost 20 years, during that time it has gained a well-deserved reputation for being a reliable and devastating semi-automatic combat shotgun. The M1014 Limited Addition is almost an exact copy of the Corp’s service shotgun and features an American Flag engraved onto the receiver. The stock of the M1014 Limited Addition is skeletonized, but still features an ample recoil pad and cheek rest. The secret behind the Benelli M1014’s reliability and combat effectiveness is its Auto Regulating Gas Operation (ARGO) system. It utilizes dual stainless steel, self-cleaning pistons that operate directly against the rotating bolt when firing. The advantage of the ARGO system is that it eliminates complex mechanics found in many comparable semi-automatic shotguns that tend to foul up faster and are more difficult to clean.
