Mossberg 990 AfterShock SPX 12Ga//14.375 FDE

The Mossberg 990 AfterShock SPX is an ultra-compact, 12-gauge gas-operated semi-automatic firearm designed for maximum maneuverability and tactical versatility in tight spaces. Built with a 14.75-inch barrel, Flat Dark Earth (FDE) Cerakote finish, and a total overall length of just 27.125 inches, it delivers 5+1 capacity without sacrificing handling control.

At its core is a durable gas system featuring nickel-boron-coated internal components for smooth operation and corrosion resistance. The SPX handguard features an integrated heat shield, multiple M-LOK accessory mounting slots, and QD sling attachment ports. Designed for fast target acquisition, the receiver is factory-cut for direct optic mounting (Shield RMSc footprint) and pairs with a winged fiber-optic front sight. The black synthetic AfterShock pistol grip includes a rubberized palm pad to reduce felt recoil, while enhanced controls—such as an oversized bolt release, knurled charging handle, top-mounted ambidextrous safety, and an enlarged, beveled loading port—ensure intuitive manipulation under pressure.
