Mossberg has announced the release of the new 990 SPX Magpul, a 12-gauge, 3-inch semi-automatic shotgun built for defensive and tactical use. Based on Mossberg’s latest semi-auto operating system, the 990 SPX Magpul combines modern ergonomics, durable construction, and accessory-ready features in a compact, purpose-driven platform.
The 990 SPX Magpul will be available with either a 14.75-inch barrel (NFA configuration) or an 18.5-inch barrel, allowing shooters to tailor the shotgun to their specific use case—from home defense to duty or training roles.
At the heart of the 990 SPX Magpul is a gas-operated system contained entirely within the forend. This design promotes smooth, consistent cycling across a broad range of ammunition. Key internal components, including the gas piston, magazine tube, hammer, and sear, receive nickel-boron and protective surface treatments to improve corrosion resistance and long-term durability.
User-focused enhancements include an enlarged, beveled loading port, a pinch-free elevator, and a high-visibility anodized orange follower. The top-mounted safety is oversized and easily accessible from either side of the shotgun, making it usable for both right- and left-handed shooters, with a clearly visible red indicator for quick status confirmation.
Modularity is a major focus of the SPX design. The shotgun features Mossberg’s SPX handguard, offering a rigid, heat-resistant structure with integrated QD sling cups and M-LOK slots for mounting lights and other accessories. Controls are designed for fast manipulation and include a knurled charging handle, oversized paddle-style bolt release, and a refined tang-mounted safety.
The receiver is optic-ready, allowing direct mounting of micro-dot optics without additional adapters. A winged fiber-optic front sight supports rapid target acquisition and co-witnessing with mounted optics.
Out back, the shotgun is fitted with a Magpul SGA stock, providing adjustable length of pull and improved recoil control. The SGA stock offers a solid shoulder interface, flexible sling-mounting options, and a familiar, durable feel that works for a wide range of shooter sizes and shooting styles.
The 990 SPX Magpul features a matte blue metal finish and is available with 5+1 capacity (14.75-inch barrel) or 7+1 capacity (18.5-inch barrel) when using 2.75-inch shells. MSRP is set at $1,309.
With the 990 SPX Magpul, Mossberg continues to expand its semi-automatic shotgun lineup with a platform that prioritizes reliability, modern ergonomics, and real-world usability—without introducing unnecessary complexity.
