    What’s Included
    • Benelli M4 EXT 12 Gauge semi-automatic shotgun

    The ARGO twin-piston gas system is the core of the M4 design and is configured here for 12 gauge with a chamber rated for 2 3/4 in and 3 in shells (76 mm). This system is designed for dependable cycling across common defensive and field loads.

    The EXT configuration features a factory extended full-length magazine tube that provides a 7+1 capacity with 2 3/4 in shells. The steel 18.5 in barrel uses screw-in choke tubes, and the two-piece ribbed polymer fore-end offers a secure grasp.

    Sighting equipment includes an LPA Italy adjustable ghost-ring rear sight with protective wings and a protected front post. The receiver carries a receiver-mounted/removable 1913 Picatinny rail secured by screws for mounting compatible optics or accessories as desired.

    The collapsible, telescoping Benelli stock offers three positions and integrates a pistol grip. The aluminum-alloy receiver wears a Flat Dark Earth Cerakote finish, paired with black polymer furniture for a purposeful two-tone appearance.

    Markings confirm its Italian manufacture and factory configuration: receiver marked "m4" and "BENELLI U.S.A. CORP – ACCOKEEK MD – MADE IN ITALY"; barrel marked "BENELLI ARMI S.P.A. – URBINO – MADE IN ITALY" and "12 GA. 3 in – 76mm – FOR 2¾ in OR 3 in SHELLS"; bolt marked "BENELLI ARMI SYSTEM"; rear sight base marked "LPA ITALY."
