Benelli’s M4 is a 12 gauge semi-automatic shotgun built around the Auto-Regulating Gas-Operated (A.R.G.O.) system, using dual stainless steel self-cleaning pistons that act directly on the bolt carrier. This design minimizes complexity and allows reliable operation with a wide range of loads without manual adjustment.

This specific M4 has been reconfigured with aftermarket components including a B&T quad rail handguard for accessory mounting, a 7-round magazine tube for increased capacity, and a 3-position collapsible stock. Additional modifications include an Aridus Industries QD shell holder mounted to the receiver, a light mount, and an Rx Arms oversized bolt release tab for improved ergonomics. Sights consist of the factory ghost ring rear sight and protected front post.
