The Panzer Arms M4 Tactical shotgun (brand part no. PAEG240TSSB) is a semi-automatic 12 gauge built on the same platform as the Benelli M4, with an 18.5-inch black barrel and a 3-inch chamber for reliable cycling with a wide range of shell loads. The 4140 steel receiver wears a durable polymer coating and a full-length Picatinny rail, and adjustable flip-up front and rear sights give shooters a fast, optic-independent aiming solution right out of the box. Among semi-auto shotguns, this M4 Tactical favors shooters who want a rugged, mil-spec-style 12 gauge ready for defense or duty use.
