Benelli M4 Tactical 12GA 3" 18.5" Black 5+1 Semi-Auto Shotgun

Benelli M4 Tactical 12GA 18.5" Black Semi-Auto Shotgun | 11703

The Benelli M4 Tactical 11703 is a 12-gauge semi-automatic shotgun built around the proven M4 platform and Benelli's A.R.G.O. gas operating system. This configuration pairs an 18.5-inch barrel with a 3-inch chamber, 5+1 capacity, black synthetic furniture, ghost-ring sights, and a receiver-mounted Picatinny rail.

The M4 has earned its reputation by keeping the operating system straightforward and durable. For buyers who want the core M4 Tactical platform without the extended-capacity tube or newer 5-position stock found on the M4 EXT, the 11703 represents a more traditional factory configuration.

Benelli A.R.G.O. Operating System

At the center of the M4 is Benelli's Auto-Regulating Gas-Operated, or A.R.G.O., system. The piston-driven action uses dual short-stroke pistons positioned close to the chamber to cycle the shotgun.

Benelli developed the A.R.G.O. system specifically for the M4 platform, and the operating system was designed for and approved by the U.S. Marine Corps. It remains one of the defining mechanical features of the M4 Tactical.

18.5" Tactical Barrel

The 11703 uses an 18.5-inch barrel, keeping the shotgun compact and maneuverable while maintaining the full-size handling characteristics of the M4 platform.

The 3-inch chamber allows the shotgun to use compatible 2¾-inch and 3-inch 12-gauge ammunition within Benelli's specifications.

5+1 Magazine Capacity

This configuration uses a tubular magazine with a listed 5+1 capacity. That gives the 11703 the traditional commercial M4 magazine setup rather than the factory 7+1 configuration found on select law-enforcement models and the newer M4 EXT.

For buyers comparing M4 manufacturer part numbers, magazine capacity is one of the most important specifications to verify because otherwise similar-looking models can be configured differently.

Ghost-Ring Sights

The M4 Tactical uses an adjustable rear ghost-ring sight paired with a front sight, giving the shooter a clear and familiar tactical sight picture.

The sighting system is designed for fast acquisition while still providing the precision needed for more deliberate shots.

Receiver-Mounted Picatinny Rail

A Picatinny rail is mounted directly to the top of the receiver, providing a factory mounting point for compatible red-dot sights and other optics.

This allows the shotgun to remain fully functional with its mechanical sights while giving the shooter an easy path to an optic-equipped M4 setup.

Black Synthetic Configuration

The 11703 uses durable black synthetic furniture suited to a working tactical shotgun. The synthetic construction is resistant to moisture and general field wear while keeping maintenance straightforward.

The result is a clean, traditional M4 appearance without the camouflage or specialty finishes found on newer configurations.
