The Panzer Arms M4 Tactical shotgun (brand part no. PAM4TSSBSS) is a semi-automatic 12 gauge built on the same operating system as the Benelli M4, with parts that are 100% interchangeable with that platform. It runs an 18.5-inch black barrel and a 3-inch chamber from a 4140 steel receiver finished in black with a durable polymer coating, and it wears an M-LOK-compatible Picatinny top rail for optics. The black skeleton synthetic stock and matching grip keep the gun light and fast to shoulder, and an ambidextrous charging handle makes it equally usable for right- or left-handed shooters. Among semi-auto shotguns, this M4 Tactical favors shooters who want a proven, mil-spec-style 12 gauge for home defense or duty use.
