Benelli M4 H20 Tactical 12GA 3" 18.5" Black 5+1 Semi-Auto Shotgun w/ Pistol Grip

Benelli M4 H2O Tactical 12GA 18.5" Semi-Auto Shotgun | 11794

The Benelli M4 H2O Tactical 11794 combines the proven M4 semi-automatic platform with a corrosion-resistant Titanium Cerakote finish designed for demanding environments. Chambered in 12 gauge, this configuration features an 18.5-inch barrel, 3-inch chamber, 5+1 capacity, fixed pistol-grip stock, ghost-ring sights, and Benelli's A.R.G.O. gas operating system.

What distinguishes the 11794 from a standard black M4 Tactical is its H2O treatment. Key exterior and operating components receive Titanium or black Cerakote finishes to provide additional protection against moisture and corrosion while maintaining the familiar handling and controls of the M4 platform.

H2O Titanium Cerakote Finish

The M4 H2O is built for buyers who expect their shotgun to encounter wet, humid, or otherwise demanding conditions. Titanium-colored Cerakote is used across major components, while additional parts receive complementary black Cerakote treatment.

The result is the distinctive two-tone H2O appearance along with increased corrosion resistance and surface durability compared with an untreated finish.

Benelli A.R.G.O. Gas System

The M4 operates with Benelli's Auto-Regulating Gas-Operated, or A.R.G.O., system. Dual stainless-steel pistons located near the chamber act directly on the bolt assembly, creating a compact gas-operated action with fewer intermediate components.

The system automatically regulates gas operation for compatible 2¾-inch and 3-inch loads without requiring manual gas-system adjustments.

18.5" Barrel & 3" Chamber

The 11794 features an 18.5-inch barrel and is chambered for both 2¾-inch and 3-inch 12-gauge ammunition.

This keeps the shotgun in the standard full-size M4 Tactical configuration while providing compatibility with a broad range of appropriate 12-gauge loads.

Fixed Pistol-Grip Stock

This M4 H2O uses a fixed black synthetic buttstock with an integrated pistol grip. The rubber/polymer grip provides a secure firing-hand position, while the recoil pad helps make the shotgun more comfortable during extended use.

For buyers who prefer a simple fixed-stock M4 rather than a telescoping configuration, the 11794 provides that setup directly from the factory.

Ghost-Ring Sights

The M4 H2O is equipped with an adjustable ghost-ring rear sight paired with a protected front blade. The system provides a clear, defined sight picture while retaining the rugged mechanical sight arrangement associated with the M4 Tactical platform.

5.25" Picatinny Optics Rail

A 5.25-inch Picatinny rail is mounted on top of the receiver, providing a factory attachment point for compatible red-dot sights and other optics.

The rail allows an optic to be added while retaining the factory ghost-ring sight system as a mechanical sighting option.

5+1 Tubular Magazine

The 11794 uses a tubular magazine with a listed 5+1 capacity. This configuration keeps the traditional proportions of the M4 Tactical while providing a factory magazine system matched to the 18.5-inch barrel.

IMPORTANT: This shotgun is supplied with a black magazine limiter. Actual usable magazine capacity may be restricted when the limiter is installed.

Integrated Sling Attachment Points

Factory sling attachment points are incorporated at the front of the shotgun and on the stock, allowing the M4 H2O to accept compatible sling configurations without requiring a complete furniture replacement.
