The Mossberg OEM security barrel (brand part number 90016) is an 18.5-inch replacement barrel built for 12 gauge Mossberg 500 and Maverick 88 six-shot models. It features a fixed cylinder bore, a factory bead front sight, and a matte blued finish that matches the rest of a factory-finished Mossberg pump gun. This is a genuine factory-spec part, so it drops in and functions exactly like the barrel your shotgun shipped with. Note that it isn’t directly compatible with the 500 Cruiser or 500 Chainsaw variants, so double-check your specific model before ordering.
