Mossberg Introduces 590A1 Professional Series
Mossberg has expanded its Professional Series lineup with the introduction of nine new models in the 590A1 pump-action shotgun series. As a proven workhorse for the military, law enforcement, and civilian users alike, the 590A1 now benefits from a range of refinements that elevate its performance.
The Professional Series is built around the field-tested 590A1 platform, which incorporates Mossberg’s hallmark features, including twin action bars, dual extractors, a positive steel-to-steel lockup, and an anti-jam elevator. What sets the Professional Series apart is the attention to detail in its enhanced assembly process, quality control, and upgrades designed to optimize functionality for demanding environments.
Among the notable improvements, the 590A1 Professional Series features heavy-walled barrels in 20-, 18.5-, and 14-inch lengths, with a cylinder bore for consistent performance across various payloads. The barrels are paired with optimized metal ghost ring rear sights and fiber optic front sights, both equipped with protective low-profile wings. These lower-profile sights improve target acquisition while allowing ease of storage and handling, particularly in vehicle-mounted scenarios.
Another key enhancement is the optic-ready receiver, which includes adapter plates for RMR®, Docter™, and Leupold® optic footprints. This feature ensures compatibility with a range of red dot sights, catering to users who demand precision and speed. The refined loading port and oversized ambidextrous safety further add to the shotgun’s user-friendly design.
The Professional Series also offers robust options for durability and customization. Users can choose between Cerakote Tungsten or Marinecote finishes for enhanced corrosion resistance. The Magpul SGA® stock with adjustable length-of-pull or a compact stock with spacer adjustments provides versatility in fit. Forends are available in Magpul MOE® configurations with M-LOK® slots or a traditional corncob style. The models also come in black or orange synthetic furniture, offering a modern aesthetic alongside functional advantages.
One of the most exciting aspects of this release is the breadth of configurations. With 9-shot, 7-shot, and 6-shot (NFA/Class 3) models, the Professional Series offers options for different needs. The compact 14-inch NFA model, in particular, provides a specialized solution for agencies and individuals seeking a shorter, highly maneuverable platform.
At SHOT Show 2024, these enhancements were first revealed, and the response highlighted the demand for such improvements in the 590A1 line. My video coverage of the event available here provides an in-depth look at these upgrades and their potential applications.
Mossberg’s 590A1 Professional Series represents a significant step forward for one of the industry’s most trusted pump-action shotguns. Whether for military, law enforcement, or civilian use, the Professional Series ensures a balance of rugged reliability and modern functionality.
