The peculiar world of “pistol-grip firearms” grows again with the new 12-gauge Mossberg 990 Aftershock SPX semi-auto boomstick.
Mossberg unveiled the original 990 AfterShock last summer, and we instantly got it on the range for some zombie-slaying fun. This new SPX version sports upgraded Magpul furniture but retains the shorty’s 3-inch chamber and impressive 5+1 capacity with 2.75-inch shells.
The key to the gun’s abbreviated 27.125-inch length is the Mossberg 990 gas system that moves the bolt return spring under the forend. This allows for the removal of the elongated stock for a birdshead-like pistol grip.
Mossberg also has models with an 18.5-inch barrel and 7+1 or 5+1 capacity. Color options include black, flat dark earth, and OD green.
A Magpul handguard offers M-LOK slots, a raised heat shield, ventilation cuts, and QD cups for easy sling attachment. The look and design are very much akin to the recently launched 990 SPX Magpul and 990 SPX Magpul – Class 3 shotguns.
The gas piston, magazine tube, hammer, and sear are covered in a nickel-boron coating with special finishes for corrosion resistance. The bolt handle, elevator, bolt release, and beveled loading port are oversized for ease of use.
These scatterguns have optics-cut receivers that are ready to host micro dots, and Mossberg added a winged front sight sporting a fiber-optic rod.
MSRPs range from $1,204 for the standard black finish to $1,260 for the colorized Cerakote finishes.
