The Panzer Arms PAM4MTSFSS M4 Marine 12 Gauge Semi-Auto pairs a corrosion-resistant nickel barrel and receiver with a rugged synthetic skeletonized stock for confident handling in harsh environments. Its 18.5" barrel, extended tube magazine, and receiver-mounted Picatinny rail create a versatile platform ready for optics and accessories while maintaining smooth, reliable cycling with a wide range of 2 3/4" and 3" loads.

This M4 Marine configuration is built around an ARGO-style piston-driven action, Beretta/Benelli Mobil pattern choke system, and flip-up sights that support fast target acquisition at the range or in a defensive role. With a 5+1 capacity, 3" chamber, and lightweight synthetic furniture, it offers a balanced option for training, home protection, or general-purpose shotgun use, backed by Panzer Arms’ reputation for value-focused innovation.
