The 590A1 Pro Series updates Mossberg’s mil-spec pump with a compact adjustable stock, Tungsten Cerakote metal and a receiver cut for direct RMSc-pattern micro red-dots. Ghost-ring rear and fiber-optic front sights stay usable until you mount an optic. A 20″ heavy-walled cylinder-bore barrel and 8+1 capacity suit defensive and duty use. Optic not included — budget for an RMSc-footprint micro-dot and a proper plate or direct mount before the first night shoot.
