Benelli M4 EXT 12GA Shotguns w/ 5-Position Stock, 7+1 Full Tube, Black Multicam

Benelli M4 EXT 18.5" 12GA Shotgun – 5-Position Stock, 7+1, MultiCam Black | 11787

The Benelli M4 EXT 11787 takes the proven M4 platform and gives it the factory upgrades many M4 owners have traditionally wanted from the start. Chambered in 12 gauge, this configuration combines an 18.5-inch barrel, 7+1 capacity, 5-position telescoping pistol-grip stock, oversized bolt release, ghost-ring sights, and a MultiCam Black finish.

The biggest difference with the M4 EXT is that Benelli did not simply change the appearance of the standard M4. The EXT incorporates meaningful upgrades to capacity, stock adjustment, and controls while retaining the ARGO operating system that defines the M4 platform.

Factory 7+1 Capacity

The M4 EXT comes equipped with a full-length magazine tube providing a 7+1 loadout. For shooters familiar with earlier M4 configurations, this is a major advantage because the extended-capacity setup is already incorporated into the shotgun from the factory.

That gives the 11787 a clean factory configuration without requiring the buyer to immediately source a replacement magazine tube or build the shotgun around aftermarket capacity upgrades.

5-Position Telescoping Stock

Benelli equips the M4 EXT with a 5-position telescoping pistol-grip stock, allowing the shooter to adjust the stock position for stance, equipment, body armor, or personal preference.

The additional adjustment gives the M4 EXT more flexibility than a fixed-stock configuration while preserving the familiar pistol-grip layout of the tactical M4 platform.

Oversized Bolt Release

One of the most useful updates on the M4 EXT is the oversized bolt release. The larger control provides a more substantial contact surface and is designed to be easier to operate when working quickly or while wearing gloves.

It is a relatively simple change, but it addresses one of the controls shooters interact with constantly during loading and operation.

MultiCam Black Finish

The 11787 is the MultiCam Black configuration of the M4 EXT. The pattern gives the shotgun a distinctive tactical appearance while separating this model from the Flat Dark Earth and other M4 EXT finish options.

For buyers specifically searching for a factory MultiCam Black M4, the manufacturer part number matters: 11787 identifies this configuration.

Ghost-Ring Sights & Picatinny Rail

The M4 EXT retains the practical sighting arrangement the M4 platform is known for, including ghost-ring sights and an integrated Picatinny rail on top of the receiver.

The factory sights provide a straightforward mechanical sighting system, while the Picatinny rail gives the shooter a ready mounting point for a compatible red-dot sight or other optic.

Benelli ARGO Operating System

At the center of the M4 EXT is Benelli's Auto-Regulating Gas-Operated, or ARGO, system. The dual-piston gas system is one of the defining features of the M4 platform and provides the semi-automatic operating system around which the shotgun was originally developed.

The EXT keeps that proven M4 operating system while updating the surrounding configuration with more capacity, greater stock adjustment, and an enlarged control surface.
