The Mossberg M990 Magpul SGA is a 12-gauge semi-auto shotgun built for shooters who want tactical versatility without compromise. With a 14.375-inch barrel and compact 33-inch overall length, this short-barrel shotgun delivers semi-automatic reliability in a platform that handles close-quarters work, home defense, or sport shooting. The gas-vent system and corrosion-resistant internals—including an enlarged loading port and smooth-operating elevator—keep the gun running reliably shot after shot, while the Magpul SGA adjustable stock and included spacers let you dial in length of pull from 12 to 14 inches for your ideal fit.
What sets the M990 apart is its modern accessory integration. The optic-ready receiver comes drilled and tapped with a Shield RMSc footprint cut, plus three additional adapter plates to mount RMR, Docter, or Leupold footprint micro dots. Metal ghost ring sights with a front fiber optic sight come standard, giving you fast, reliable aiming right out of the box. The tactical forend features integrated M-Lok slots and QD ports, so you can mount lights, grips, and other gear exactly where you need it—and a heat shield protects your hands during extended use.
Built for shooters who demand both performance and flexibility, the M990 Magpul SGA balances combat-grade ergonomics with intuitive controls: an oversized safety and bolt release make operation smooth under stress. The 5+1 capacity (5-round magazine plus 1 in the chamber) and 3-inch chamber handle a full range of 12-gauge loads. At 7.35 pounds, it's lightweight enough for extended handling yet substantial enough to manage recoil.
