The Panzer Arms M4 shotgun (brand part no. PAM4MTSSS) is a semi-automatic 12 gauge built on the Benelli M4 platform, finished in a corrosion-resistant nickel over its 18.5-inch barrel and 4140 steel receiver. A black fixed synthetic stock and matching black polymer grip give it a traditional, no-frills profile, while a full-length Picatinny rail stands ready for optics. Ambidextrous controls round out the design. Among semi-auto shotguns, this M4 favors shooters who want a durable, marine-grade-finished 12 gauge for defense or field use.
