Benelli M4 EXT 12 GA 18.5" 7+1 FDE Shotgun

Benelli M4 EXT 18.5" 12GA FDE Shotgun – 5-Position Stock & 7+1 Capacity | 11788

The Benelli M4 EXT 11788 is a Flat Dark Earth configuration of the updated M4 EXT platform, combining the proven M4 operating system with several factory features that shooters have traditionally added after purchase. This 12-gauge semi-automatic pairs an 18.5-inch barrel with 7+1 capacity, a 5-position telescoping pistol-grip stock, oversized bolt release, ghost-ring sights, and an integrated Picatinny optics rail.

The M4 EXT is more than a finish change. Benelli designed this version around greater capacity, more stock adjustment, and improved access to the controls while retaining the A.R.G.O. gas system that has defined the M4 platform for years.

Factory 7+1 Capacity

The M4 EXT comes from the factory with a full-capacity 7+1 magazine configuration. For M4 buyers, that is a significant advantage because the extended-capacity setup is already incorporated into the shotgun rather than requiring an immediate magazine-tube upgrade.

The result is a cleaner factory configuration for shooters who already know they want the higher-capacity M4 setup.

5-Position Telescoping Stock

The 11788 uses Benelli's 5-position telescoping stock with an integrated pistol grip. Multiple adjustment positions allow the shooter to tailor the stock length around body armor, equipment, shooting stance, or personal preference.

Compared with a fixed-stock M4, the added range of adjustment makes the shotgun more adaptable without changing the familiar pistol-grip layout.

Oversized Bolt Release

One of the practical updates on the M4 EXT is the oversized bolt release. The larger control surface is easier to locate and operate quickly, particularly when wearing gloves or working under demanding conditions.

It is a simple change, but it improves one of the controls the shooter interacts with regularly during loading and operation.

Flat Dark Earth Configuration

The 11788 is the Flat Dark Earth version of the M4 EXT. The FDE treatment gives the shotgun a distinctive factory appearance while separating it from the H2O and MultiCam Black configurations in the EXT lineup.

For buyers specifically looking for the factory FDE M4 EXT, manufacturer part number 11788 and UPC 650350117882 identify this configuration.

Ghost-Ring Sights & Picatinny Rail

The M4 EXT retains the practical ghost-ring sighting system associated with the M4 platform. The rear sight provides a fast, familiar sight picture, while the front sight gives the shooter a clear reference for rapid alignment.

An integrated Picatinny rail on top of the receiver provides a factory mounting point for a compatible red-dot sight or other optic.

Benelli A.R.G.O. Operating System

At the heart of the M4 EXT is Benelli's Auto-Regulating Gas-Operated, or A.R.G.O., system. The dual short-stroke piston design operates close to the chamber and is engineered to provide reliable semi-automatic cycling across compatible 12-gauge loads.

The EXT keeps that established M4 operating system while updating the surrounding configuration with more capacity, greater stock adjustment, and enlarged controls.
