The Mossberg Q-DC will fit both the model 500 and 590. With a
Receiver adapter machined from a block of 6061-T6 USA made aluminum and
commonly being accused of being over-engineered, it’ll hold up extreme
use. Type III hardcoat anodizing to military specifications gives it a
durable finish, while the parkerized steel latch and stainless steel
torsion spring keep the Carrier in place. With a skeletonized back plate
to shave weight without sacrificing strength, a blind tapped holes that
can’t be over-tightened at the rear attachment point, and a steel
Chicago screw for the forward attachment point, the Q-DC addresses many
issues currently seen in other rigid carriers. The serial number cutout
makes life easier on armorers who need to take inventory without having
to remove the unit.
The Mossberg Q-DC comes with one (1) Receiver Adapter, one (1)
Detachable carrier, appropriate mounting hardware, and threadlocker.
Note: Like many shell carriers out there, there may be
interference if the forend extends beyond the edge of the receiver when
the action is opened. Trimming of the forend may be required. The Q-DC
is compatible with both Magpul and Surefire forends. It is also will not
interfere with the Magpul single point sling adapter.
