Benelli Armi S.p.A. is an Italian firearms manufacturer founded in 1967 in Urbino. The company's Inertia Driven system uses recoil energy to cycle the action without a gas port, reducing fouling and parts count. The Super Black Eagle series handles 2.75-, 3-, and 3.5-inch shells and is a reference point for waterfowl hunters. The M4 Tactical semi-automatic shotgun is issued by military and law enforcement agencies. The Nova and SuperNova pump-action shotguns use a polymer receiver integrated with the stock. The Ethos semi-automatic line targets hunters and competitive shooters. The LUPO bolt-action rifle offers sub-MOA accuracy and an adjustable stock. Benelli backs its firearms with a 10-year warranty.
