The Benelli M4 EXT is a semi-automatic 12 Gauge tactical shotgun built around Benelli’s ARGO Auto-Regulating Gas-Operated system. Its dual short-stroke gas pistons provide reliable cycling across a broad range of loads while helping keep fouling away from the action. This configuration combines an 18.5-inch barrel, 7+1 capacity, five-position telescoping stock, pistol grip, ghost ring sights, and a Picatinny rail for adaptable field use. The MultiCam Black finish provides a distinctive protective exterior for defensive, duty, and training applications.
