NORTH HAVEN, CT – Following on the unprecedented success of the Mossberg 590® Shockwave pump action, Mossberg is pleased to announce the all-new 990 Aftershock, a 12-gauge, 3-inch semi-auto version of this small in size, but big on performance tactical firearm. This full-featured and easy to maneuver platform is available with 14.75-inch or 18.5-inch barrel options and 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 5-shot magazine.
The well-designed exterior of the 990 Aftershock epitomizes big tactical performance in a compact platform. The Aftershock 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 combined for a more positive hold.

Completing the 990 is the choice of 14.75 or 18.5-inch cylinder bore barrels equipped with a high-quality 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 which attaches easily to the receiver. The laser is adjustable for windage and elevation, and the fixture provides multiple touchpad activation points.
Mossberg continues to deliver innovation, reliability, and exceptional tactical performance with their lines of 590A1™/590 pump-actions and 940® Pro Tactical semi-autos. Now joining the family is the new 990 Aftershock - a premium defensive tool in a small package. For more information, please visit www.mossberg.com .
