Features

Engineered for law enforcement, home defense, and marine use, this semi-automatic shotgun delivers consistent performance you can trust, whether on land or at sea.

This lightweight and fast-handling M4 Tactical features the renowned A.R.G.O. piston-driven semi-automatic action, ensuring smooth, dependable cycling with everything from light target loads to heavy 3-inch magnum shells. Its extended 6-round magazine tube provides increased capacity for sustained shooting, while the integrated sling attachment points make it ideal for rapid deployment in high-stress situations.

Designed with versatility in mind, the M4 Marine Tactical includes a precision-machined top rail for mounting optics and standard ghost ring sights for fast, accurate target acquisition. The fixed skeletonized stock offers exceptional control and stability, even in demanding tactical scenarios.

What sets the Marine Grade model apart is its Electroless Nickel-Phosphorus Plating on the barrel, receiver, magazine tube, and internal components. This advanced finish provides superior corrosion resistance and long-lasting durability, especially in saltwater and extreme weather conditions. The bolt’s black-over-chrome plating adds both strength and a sleek visual contrast against the black synthetic stock, creating a professional, purpose-built appearance.
