Mossberg® Introduces 990™ SPX Magpul® Semi-Auto Shotgun

Mossberg is proud to introduce the 990 SPX Magpul, a 12-gauge, 3-inch semi-auto tactical shotgun designed to deliver proven performance with modern enhancements for today’s shooters. Built on Mossberg’s latest semi-auto platform, the 990 SPX Magpul blends rugged reliability, advanced ergonomics, and accessory-ready versatility in a compact, easy-handling package. The 990 SPX Magpul is offered with 14.75-inch (NFA) or 18.5-inch barrel options to meet a wide range of defensive and tactical needs.

The 990 SPX Magpul is driven by a robust gas-operated system housed entirely within the forend, engineered for smooth, consistent cycling across a variety of ammunition types. Critical internal components—including the gas piston, magazine tube, hammer, and sear—are treated with nickel-boron coatings and specialized finishes to enhance corrosion resistance and durability. Functional enhancements include an enlarged, beveled loading port, elongated pinch-free elevator, and a high-visibility anodized orange follower. A top-mounted safety, oversized and ergonomically shaped, is easily accessible for both right- and left-handed shooters and features a clearly visible red indicator.

Designed with modularity in mind, the 990 SPX Magpul features the SPX handguard, providing a rigid, heat-resistant platform with integrated QD cups and M-LOK® slots for mounting lights, grips, and other accessories. Shooter controls are optimized for fast, intuitive operation and include a knurled charging handle, oversized paddle-style bolt release, and a refined tang-mounted safety switch.

The 990 SPX Magpul is also equipped with an optic-ready receiver cut, allowing direct mounting of micro-dot optics. A winged front fiber optic sight completes the sighting system, offering rapid target acquisition and seamless co-witness capability with mounted optics.

Ergonomics and shootability are further enhanced with the inclusion of a Magpul SGA® stock, providing a stable, adjustable interface designed to fit a wide range of shooters. The SGA stock delivers improved recoil management, a secure shoulder weld, and mounting options for slings, while maintaining the streamlined handling characteristics of the platform.

Completing the 990 SPX Magpul are 14.75-inch or 18.5-inch Accu-Choke® barrels, 5+1 and 7+1 capacity respectively, with 2.75-inch shotshells, and a matte blue metal finish.

With the introduction of the 990 SPX Magpul, Mossberg continues its commitment to innovation, reliability, and tactical performance—delivering a premium semi-auto shotgun that combines modern features with proven Mossberg durability.
