The Mossberg 590A1 M-LOK is a 12 Gauge pump-action shotgun built around the proven 590A1 platform. Its heavy-walled 20-inch barrel, Parkerized finish, metal trigger guard, and metal safety button provide the durable construction associated with the military-qualified 590A1 series. The cylinder-bore barrel accepts 3-inch shells, while the extended 8+1 capacity provides substantial onboard firepower. XS ghost ring sights support rapid alignment, and the M-LOK forend allows users to configure the shotgun with compatible accessories. A fixed black synthetic stock with four-shell storage completes the practical duty-oriented configuration.
