description Benelli M4 Overview
Designed around military and law enforcement requirements, the Benelli M4 is a 12-gauge semi-automatic combat shotgun. Its defining feature is the Auto-Regulating Gas-Operated system, usually shortened to ARGO. This uses a twin-piston gas mechanism to cycle the action, distinguishing the M4 from Benelli shotguns that use inertia operation. A rotating bolt and tubular magazine are central parts of the design.
The M4's association with the United States Marine Corps reflects its intended role as a durable service shotgun for demanding conditions and close-range use. It suits professional users and experienced shooters interested in a gas-operated tactical platform. Its appeal rests on the operating system and service background, rather than an assumption that every stock or accessory configuration is identical.
