Mossberg 990 Aftershock Angled

Mossberg has announced the all-new 990 Aftershock, a 12-gauge, 3” semi-automatic version of the 590 Shockwave tactical firearm introduced in 2017. This platform is available with 14.75” or 18.5” barrel options and a 14.75” 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 fore-end. 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 fore-end 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 990 Aftershock’s exterior emphasizes its purpose of tactical performance in a compact platform. The black synthetic Aftershock 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 fore-end 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” cylinder bore barrels equipped with a high-quality LPA front fiber optic sight; 5+1 total capacity (with 2.75” shotshells); and matte blue metal finish. The 14.75” 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.
