Description
Used Benelli M4 H2O 12 Gauge – 18.5" Barrel, Pistol Grip, Ghost Ring Sights
The Benelli M4 H2O Tactical is the ultimate combat-proven semi-auto shotgun, trusted by the United States Marine Corps since 1999. Designed to dominate in the harshest environments, this used 12 gauge shotgun features an 18.5-inch barrel, titanium Cerakote finish, and Benelli’s legendary Auto-Regulating Gas-Operated (A.R.G.O.) system for flawless, self-cleaning reliability.
This model comes equipped with a pistol grip tactical stock, Picatinny rail (mounted at the factory), fully adjustable ghost ring rear sight, and windage-adjustable front sight. Rugged, simple, and nearly impossible to make fail, the M4 H2O cycles a wide range of loads—from light tactical shells to heavy slugs—with ease and absolute dependability.
Finished in a corrosion-resistant Titanium Cerakote, the M4 H2O is perfect for maritime environments, duty use, or anyone demanding the very best in semi-automatic tactical shotguns.
