The Mossberg 590A1 is a pump-action 12 gauge shotgun built to exacting standards. Its 20″ heavy-walled barrel is finished in Tungsten Cerakote, while the receiver features Parkerized finish. The shotgun meets MIL-SPEC 3443G durability requirements and incorporates a metal trigger guard and safety, along with a clean out mag tube.
Sighting is handled by a ghost-ring rear sight paired with a fiber-optic front sight. The synthetic stock includes a spacer for fit adjustment, and the corncob forend provides a secure grip. Standard pump-action features include dual extractors, steel-to-steel lockup, a top-mounted ambidextrous safety, twin action bars, and an anti-jam elevator.
The 590A1 ships with a cylinder bore choke and carries a 6-round capacity. This combination of heavy-walled construction, metal components, and proven mechanical design makes the Mossberg 590A1 Pro well-suited for defensive use and professional applications.
