The 990 Aftershock is a 12-gauge, 3-inch semi-auto version of the 590 Shockwave pump-action shotgun. The full-featured and easy-to-maneuver platform is available with 14.75-inch or 18.5-inch-barrel options as well as a 14.75-inch version equipped with a Crimson Trace Lasersaddle.

At the heart of the 990 Aftershock is a durable gas-operating system that is fully contained within the forend. Internal parts (gas piston, magazine tube, hammer, and sear) feature a nickel-boron coating and a special finish for enhanced corrosion resistance and smooth, reliable cycling. To further improve performance, the 990 has an enlarged and beveled loading port designed for ease of loading; elongated, pinch-free elevator; and anodized, bright orange follower. The oversized, ergonomic top-mounted safety can easily be operated by a left- or right-handed shooter and features a highly visible red indicator. Enhanced functionality continues with the knurled charging handle; oversized, paddle-style bolt release; strapped forend for a firm hold and to keep hands clear of the muzzle; and a M-LOK accessory adaptor with mounting slots on the sides and bottom attached to the extended five-shot magazine.

The black synthetic grip is uniquely shaped for an ergonomic, secure grip and features a rubberized palm pad to minimize felt recoil. A quick-detachment cup is incorporated on the rear of the grip. The matching black synthetic forend is streamlined, has an attached embossed strap, and wears Mossberg’s signature texturing—all of which combine for a more positive hold. Completing the 990 is the choice of 14.75- or 18.5-inch cylinder bore barrels equipped with a LPA front fiber optic sight; 5+1 total capacity (with 2.75-inch shotshells); and matte blue metal finish. The 14.75-inch version is also available with a Crimson Trace Lasersaddle that attaches easily to the receiver. The laser is adjustable for windage and elevation, and the fixture provides multiple touchpad activation points. SRP: $1,120-$1,302. mossberg.com
