Key Features
Mil-Spec 3443E Compliance
Constructed to meet military specifications, the 590A1 features a heavy-walled barrel, a metal trigger guard, and a metal safety button. This design ensures superior durability and operational integrity under extreme conditions, setting it apart from standard defensive shotguns.
Marinecote Finish
The application of Marinecote provides an advanced layer of corrosion and abrasion resistance. This finish is specifically engineered to protect the weapon in humid, salty, or otherwise corrosive environments, extending its service life and maintaining operational reliability in adverse conditions. The finish also aids in mitigating glare.
M-LOK Forend Integration
An integrated M-LOK compatible forend allows for direct attachment of mission-critical accessories such as tactical lights, laser aiming devices, and vertical grips. This system facilitates rapid customization without significant weight or bulk penalty, enhancing the shotgun’s adaptability to diverse operational requirements.
Positive Cycling Action
Utilizing Mossberg’s proven twin action bars, the 590A1 ensures smooth, non-binding pump operation. This design is critical for reliable shell feeding and extraction, enabling consistent and rapid target engagement under stress. The anti-jam lifter further mitigates stoppages.
Robust Capacity and Chambering
