The Panzer Arms M4 Pro AI Tactical in 12 gauge (brand part no. PAM4NCSBRBTMFSS) is a semi-automatic shotgun with a dual-piston gas system and an 18.5-inch ported barrel. A distressed copper Cerakote covers the barrel and receiver, set against a matte black skeleton stock and an anodized aluminum M-LOK handguard.
