Description
The Benelli M4 12 Ga, 18.5″ Barrel, Pistol Grip, Ghost Ring Sights, Black is a semi-automatic tactical shotgun built to the U.S. military’s M1014 specification. It’s engineered for extreme reliability under pressure, featuring a robust inertia-driven system and a ghost ring sight setup for rapid target acquisition. This model is the civilian-legal version of the combat-proven platform, offering a compact 18.5-inch barrel and a pistol grip stock for superior control in confined spaces. When it comes to home defense or duty use, this shotgun is designed to perform when it counts.
Key Features
- Military-Proven Action: The Benelli Auto Regulating Gas Operated (ARGO) system is derived from the military M1014. It’s short-stroke, self-cleaning, and built to cycle everything from light target loads to 3-inch magnum slugs without adjustment.
- Ghost Ring Sights: The rear ghost ring and front post sight provide a fast, instinctive sight picture for close-quarters engagements. The front sight is a high-visibility red fiber optic for quick picks in low light.
- Pistol Grip Stock: The fixed pistol grip and collapsible stock (C-stock) offer multiple length-of-pull positions and superior weapon manipulation, especially when wearing body armor or operating from vehicles.
- Corrosion Resistance: The receiver and barrel are finished with a durable, non-reflective black phosphate coating. Internal components are treated to resist corrosion from moisture and solvents.
- Modular Design: The M4 platform is highly modular. The 18.5-inch barrel keeps the overall length manageable at just 40 inches. It accepts a wide range of aftermarket parts from brands like SureFire for weapon lights and Mesa Tactical for side-saddles.

Pros & Cons
Pros: Legendary reliability in adverse conditions. The military pedigree means every component is overbuilt for duty use. The ghost ring sights are vastly superior to a simple bead for defensive shooting. The modularity allows for easy customization—adding a light like a SureFire Scout or a shell carrier is drop-in ready. The action runs cleanly and requires minimal maintenance.
Cons: The price point at $1691.90 is a significant investment. The weight is noticeable compared to lighter shotguns, which can be a factor during extended carry. The 5+1 capacity is standard but less than some modern tactical models; however, the design is mil-spec compatible and can be upgraded with aftermarket extended tubes.
Frequently Asked Questions
Q: Is the collapsible stock legal for civilian ownership?
A: Yes. This model is specifically configured for the civilian market and is 922(r) compliant. The collapsible stock is a fixed feature and does not require any special paperwork or tax stamps, making it ready for your FFL transfer upon purchase.
Q: Can the magazine tube be extended for more capacity?
A: Absolutely. The design accepts aftermarket extended magazine tubes from several reputable manufacturers. Installing one typically requires basic tools and is a straightforward process that increases capacity to 7+1 or more, a popular and practical upgrade for defensive use.
Q: How does it handle different types of ammunition?
A: The ARGO system is designed to cycle a wide range of loads without manual adjustment. From light 2 3/4″ target loads to full-power 3″ magnum buckshot and slugs, it should feed and eject reliably. That said, you should always test your defensive ammunition to ensure flawless function in your specific firearm.
