Benelli M4 18.5" 12GA Semi-Automatic Shotgun with Pistol Grip | 11707
The Benelli M4 11707 is one of the most recognizable configurations of the M4 Tactical platform. Chambered in 12 gauge, it 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 proven A.R.G.O. gas operating system.
For shooters who want the traditional M4 setup without a collapsible stock or extended magazine tube, the 11707 keeps the platform straightforward. It delivers the core features that made the M4 a benchmark tactical semi-automatic shotgun while retaining a simple fixed-stock configuration.
Benelli A.R.G.O. Operating System
The M4 is built around 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.
This operating system was developed for the M4 platform and approved by the U.S. Marine Corps. Its simple, compact design is one of the defining mechanical features of the shotgun and a major reason the M4 has earned such a strong reputation for professional use.
18.5" Tactical Barrel
The 11707 uses an 18.5-inch barrel, giving the shotgun a compact overall profile while retaining the handling characteristics expected from a full-size tactical shotgun.
The barrel is paired with a 3-inch chamber, allowing the M4 to use compatible 2¾-inch and 3-inch 12-gauge ammunition.
Fixed Pistol-Grip Stock
This configuration uses Benelli's fixed synthetic pistol-grip stock rather than the collapsible or 5-position stock found on other M4 variants.
The pistol grip gives the shooter a positive firing-hand position while the fixed stock keeps the setup simple, solid, and familiar. For buyers comparing M4 part numbers, the stock configuration is one of the most important differences to verify.
5+1 Magazine Capacity
The Benelli M4 11707 comes with a 5-round tubular magazine, providing a listed 5+1 capacity.
This is the standard-capacity configuration for this specific model and distinguishes it from newer M4 EXT and select law-enforcement configurations equipped with factory 7-round magazine systems.
Ghost-Ring Sights & Picatinny Rail
The M4 uses an adjustable ghost-ring rear sight paired with a protected front sight, giving the shooter a fast and familiar tactical sight picture.
A Picatinny rail mounted along the top of the receiver provides a factory mounting point for a compatible red-dot sight or other optic.
Proven M4 Tactical Platform
The 11707 keeps the M4 focused on the features that matter most: reliable semi-automatic operation, straightforward controls, durable synthetic furniture, practical sights, and an optics-ready receiver.
It is a particularly good fit for buyers who want the established M4 Tactical platform in a conventional fixed-stock configuration rather than starting with one of the newer extended-capacity or telescoping-stock variants.
