The Mossberg 990 Magpul is a 12-gauge semi-auto shotgun built for shooters who want modern tactical features without compromise. With an 18.5" barrel, 3" chamber, and 7+1 capacity, this is a compact, hard-hitting platform suitable for home defense, sport shooting, or patrol work. The 990 delivers the reliability Mossberg is known for—a proven gas-vent operating system with corrosion-resistant internals—wrapped in a contemporary chassis that accepts modern optics and accessories out of the box.
What sets the 990 Magpul apart is its factory-integrated modularity. The receiver is already cut and drilled for optics: it ships optic-ready with adapter plates for RMSc, RMR, Docter, and Leupold footprints, so you can mount your preferred micro-dot or reflex sight immediately. The rear ghost ring sight and fiber optic front sight are included, giving you a capable sighting system while you decide on glass. The oversized, ergonomic safety and bolt release are easy to manipulate even with gloved hands.
The Magpul SGA adjustable stock lets you dial in length of pull from 12" to 14" with included spacers—crucial for different shooting positions, body armor, or simply sharing the gun among shooters of different builds. The tactical forend features integrated M-Lok slots, QD attachment points, and a heat shield to protect your support hand during extended shooting. The enlarged loading port and elongated elevator make feeding smooth and fast. At 7.75 lbs and 37.25" overall, it's nimble enough to move with but substantial enough to manage recoil.
Mossberg equipped this 990 with an Accu-Choke system set to Cylinder Bore, giving you a clean slate to pattern different loads or swap chokes as your mission changes. The matte-blue barrel and black furniture keep things low-profile and rugged-looking. This is a shotgun that works hard and accepts upgrades without fuss.
