The Benelli M4 is a battle-proven semi-automatic shotgun, trusted by the United States Marine Corps since 1998 for its rugged reliability and performance. At the core of its design is the Auto-Regulated Gas-Operated (A.R.G.O.) system, utilizing self-cleaning dual stainless steel pistons that directly engage the bolt assembly, eliminating the need for complex gas mechanisms. This allows the M4 to cycle nearly any 3” shell—from heavy 00 buckshot to lighter field loads—without manual adjustments.

This model features a fixed synthetic stock, but includes a factory-installed 3-position recoil tube, allowing for a straightforward swap to a collapsible stock if desired. The standard 5-round magazine tube can also be easily swapped to a 7-round tube, bringing total capacity to 9 shells when ghost loading.

The M4 is equipped with a receiver-mounted Picatinny rail, allowing for optics or red dot sights, and comes standard with ghost ring sights for rapid target acquisition. Designed for military, law enforcement, home defense, or rugged outdoor environments, the Benelli M4 is a premier tactical shotgun built to perform under extreme conditions.
