Mossberg 990 AfterShock: Semi-Auto Shockwave Power in 2025
The firearms world just got louder and faster. Mossberg has introduced the Mossberg 990 AfterShock, a semi-automatic 12-gauge shotgun that blends compact dimensions with tactical capability. Slated for release in early 2025, this new entry marks a significant evolution from the pump-action 590 Shockwave, delivering quicker follow-up shots with a gas-operating system, M-LOK versatility, and even an optional integrated laser.
A Modern Evolution of the Shockwave
Mossberg fans are no strangers to innovation, and the 990 AfterShock takes things further by combining the appeal of "other firearms" with semi-automatic speed. Offered with either a 14.75-inch or 18.5-inch barrel, this shotgun is designed for home defense, close-quarters tactical use, and professional applications like door breaching. Like its predecessor, the 990 AfterShock is compact and maneuverable, but it trades the pump for gas making it smoother and faster under pressure.

Built for Reliability and Customization
The 990 AfterShock’s gas-operating system is tucked neatly into the forend, allowing for clean cycling and reduced recoil. A standout feature is the AfterShock grip, ergonomically shaped with a rubberized palm pad to dampen felt recoil crucial in a shotgun of this size. The included M-LOK-compatible magazine extension opens the door to flashlights, grips, and sling attachments.
On the #83003 model, the Crimson Trace Lasersaddle offers a 5mW laser beam adjustable for windage and elevation, with intuitive touchpads on both sides of the receiver ideal for low-light environments and defensive use.
Additional features include:
Oversized, ambidextrous safety
Knurled charging handle for secure operation
Ergonomic bolt release and enlarged loading port
Corrosion-resistant nickel-boron coated internals for long-term durability

How It Stacks Up
The Mossberg 990 AfterShock enters a crowded but competitive space, going up against the likes of the Beretta 1301 Tactical and FN SLP MK I. It distinguishes itself with its compact profile, aggressive pricing, and modularity. Unlike the pump-action Shockwave, the 990’s semi-auto system provides quicker follow-ups a potentially life-saving difference in high-stress defensive situations.

Firearms reviewers have already begun testing the 990 AfterShock. Pew Pew Tactical highlighted its maneuverability and low-profile gas system, though questioned how well it will hold up to Mossberg’s legacy. Guns.com praised its breaching potential and laser option, but did note some wrist fatigue from the compact recoil impulse.
