    What’s Included
    • Browning Auto-5 Magnum Twenty 20 Gauge shotgun

    The Magnum Twenty designation identifies this Auto-5 as the 20-gauge magnum variant with a 3 inch chamber and 5-round capacity. The long-recoil system uses Browning's friction-ring and bronze friction piece, and this example includes the left-side magazine cut-off lever typical of the design.

    The 28 inch Belgian Special Steel barrel has a ventilated rib with a matted top and a single front bead. It carries the FN star choke code indicating Full, matching the fixed Full (F) choke noted for this gun. Chambered for 3 inch shells, it offers the magnum capability that defines the Magnum Twenty model.

    The polished blued steel receiver is factory scroll engraved and paired with a gold-tone trigger. Right-side ejection, a round bolt handle, and a knurled steel magazine cap round out the classic Auto-5 control layout and handling features.

    Checkered walnut furniture includes a glossy pistol-grip stock and matching fore-end, with a 14.0 inch length of pull. Belgian markings include Liège proof marks and a "MADE IN BELGIUM" barrel marking. The serial format identifies model code 161 as the Magnum Twenty variant.
