Mossberg 990 Aftershock SPX Shotgun, 12 Gauge, 14.375-Inch Barrel, Black

The Mossberg 990 Aftershock SPX in 12 gauge with a 14.375-inch barrel and black finish (brand part no. 83010) is an ultra-compact, magazine-fed shotgun built for easy maneuvering with a host of tactical features. Mossberg accepts a 3-inch chamber, feeds a 5+1 capacity magazine, and ships optic-ready with a Shield RMSc footprint plus three additional adapter plates for RMR, Docter, and Leupold-pattern optics. The AfterShock grip minimizes felt recoil, and the redesigned forend integrates a heat shield with M-LOK accessory slots and QD sling ports. A knurled charging handle, oversized ergonomic safety and bolt release, and an enlarged, beveled loading port speed up manipulation and reloading, and a front fiber optic sight with protective wings rounds out the package. Among ultra-compact semi-auto shotguns, the 990 Aftershock SPX favors shooters who want direct optic mounting and M-LOK accessory options in a maneuverable package.
