Benelli M4 H2O 12 Gauge Semiautomatic ARGO Shotgun

The Benelli M4 H2O 12 Gauge Semiautomatic ARGO Shotgun is the ultimate fusion of military-grade engineering and civilian-ready adaptability. Designed as the civilian counterpart to the legendary U.S. Marine Corps M1014 combat shotgun, this firearm boasts a Titanium Cerakote finish for unmatched corrosion resistance and rugged reliability. Built to thrive in saltwater environments, heavy rain, or tactical scenarios, the M4 H2O is engineered for hunters, home defenders, and professionals who demand flawless semi-auto performance. Looking for a rugged pump-action alternative? Check out the Benelli Nova—a durable and reliable option for field and home defense use.

Key Features & Benefits

1. Titanium Cerakote Finish

• Marine-grade corrosion resistance ensures longevity in extreme conditions (saltwater, humidity, rain). 
• Matte gray finish minimizes glare for stealth in tactical or hunting environments. 

2. Auto-Regulating Gas-Operated (ARGO) System

• Self-cleaning dual stainless steel pistons cycle flawlessly between 2-3/4″ light field loads and 3″ magnum buckshot without manual adjustments. 
• Battle-tested reliability trusted by military forces since 1998. 

3. Enhanced Ergonomics & Control

• Pistol-grip synthetic buttstock with recoil-reducing pad improves accuracy and comfort during rapid fire. 
• Ambidextrous sling points for versatile carry configurations (single-point, two-point). 

4. Rapid Target Acquisition

• Adjustable ghost ring rear sight and high-visibility front blade for fast, precise aiming in low-light scenarios. 
• 5.25″ Picatinny rail supports optics, red dot sights, or tactical lights (ideal for home defense or night hunting). 

5. Proven Durability

• Aircraft-grade aluminum receiver and chrome-lined barrel resist wear, heat, and fouling. 
• Over 12,000 rounds tested in military trials with zero malfunctions. 

Why the Benelli M4 H2O Stands Out

• Military Heritage: Direct descendant of the USMC M1014—trusted in combat zones like Iraq and Afghanistan. 
• Low-Maintenance Design: The ARGO system’s self-regulating gas operation eliminates complex adjustments, even with mixed ammunition. 
• All-Weather Ready: Saltwater-proof Cerakote and sealed trigger group outperform traditional blued finishes. 
• Home Defense Optimization: Compact 18.5″ barrel (MIL-SPEC) balances maneuverability and stopping power.

FAQs:

Is the Benelli M4 H2O suitable for slug hunting?

The gas-operated action absorbs 30% more recoil than inertia-driven systems, allowing faster follow-up shots.
