Benelli M4 12Ga Shotgun w/ 18.5" Barrel, Pistol Grip & Ghost Ring Sights OD Green

Benelli M4 Tactical 18.5" 12GA OD Green Semi-Auto Shotgun | 11797

The Benelli M4 Tactical 11797 is a limited OD Green configuration of the proven M4 platform. Chambered in 12 gauge, this model combines an 18.5-inch barrel, 5+1 capacity, fixed synthetic pistol-grip stock, ghost-ring sights, and a receiver-mounted Picatinny rail with Benelli's A.R.G.O. gas operating system.

For buyers who already know the M4, the standout feature here is the factory OD Green finish. The 11797 keeps the traditional M4 Tactical layout while giving the shotgun a distinctive appearance that separates it from the more common black configurations.

Limited OD Green Configuration

The 11797 features an OD Green finish with black controls and hardware, giving the M4 a subdued field-oriented appearance without changing the core operating system or handling characteristics of the platform.

This model was produced as a limited-run configuration, making the exact manufacturer part number especially important for collectors and buyers specifically searching for the factory OD Green M4.

Benelli A.R.G.O. Operating System

At the heart of the M4 is Benelli's Auto-Regulating Gas-Operated, or A.R.G.O., system. The short-stroke dual-piston design was developed specifically for the M4 platform and operates close to the chamber.

The M4's A.R.G.O. system was originally developed for the U.S. Marine Corps and was later adopted as the U.S. Joint Services combat shotgun operating system. It remains one of the defining mechanical features of the M4 platform.

18.5" Tactical Barrel

The 11797 uses an 18.5-inch barrel with a 3-inch chamber, keeping the shotgun compact while maintaining the familiar balance and handling of the standard M4 Tactical.

The barrel is paired with a Modified choke and is designed for compatible 2¾-inch and 3-inch 12-gauge ammunition.

Fixed Pistol-Grip Stock

This configuration uses Benelli's fixed synthetic pistol-grip stock. The pistol grip provides a positive firing-hand position while the fixed stock keeps the setup straightforward and solid.

For buyers comparing M4 configurations, this is an important distinction from models equipped with collapsible or newer 5-position telescoping stocks.

5+1 Magazine Capacity

The 11797 uses a tubular magazine with a listed 5+1 capacity. This is the traditional commercial M4 magazine configuration rather than the factory 7+1 setup found on select law-enforcement and newer M4 EXT models.

Ghost-Ring Sights

The M4 Tactical uses a ghost-ring sighting system designed to provide a fast, clear sight picture. The rear aperture and protected front sight give the shooter a practical mechanical sighting setup for a tactical shotgun.

Receiver-Mounted Picatinny Rail

A Picatinny rail along the top of the receiver provides a factory mounting surface for compatible red-dot sights and other optics.

The shotgun remains fully usable with its mechanical sights while giving the shooter a straightforward path to an optic-equipped M4 configuration.
