Following on the unprecedented success of the Mossberg 590 Shockwave pump action launched in 2017, Mossberg is pleased to announce the 990 Aftershock, a 12-gauge, 3-inch semi-auto version of this non-NFA firearm. This small-in-size, but big on performance firearm is available with 14.75-inch or 18.5-inch barrel lengths and with an optional Crimson Trace Lasersaddle(14.75-inch barrel length only).

990 Aftershock Heart

At the heart of the 990 Aftershock is a durable gas-operating system that is fully contained within the forend. Internal parts feature a nickel-boron coating and a special finish for enhanced corrosion resistance and reliable cycling. To further improve performance, the 990 has an enlarged and beveled loading port; elongated, pinch-free elevator; and anodized, bright orange follower. The oversized, ergonomic top-mounted safety can be operated by a left or right-handed shooter. 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.

The exterior includes the Aftershock black synthetic grip, uniquely shaped for an ergonomic, secure hold. The grip also features a rubberized palm pad to minimize felt recoil and a quick-detachment cup for sling attachment. The matching black synthetic forend is streamlined, has an attached embossed strap, and wears Mossberg’s signature texturing. Completing the 990 is a cylinder bore barrel equipped with an LPA front fiber optic sight; 5+1 total capacity (with 2.75-inch shotshells); and matte blue metal finish. 

The 14.75-inch 990 Aftershock 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.The 990 Aftershock from Mossberg is a premium defensive tool in a small package.
