Primary Magazine Release:
Press the square magazine release button above trigger and
the magazine will release. (Fig. e-1,)
Secondary Magazine Release:
Press the magazine release catch in front of the magazine well
and the magazine will release. (Fig. e-2, A)
Magazine Empty Reload:
Upon firing the last round, the bolt will lock to the rear,
enabling faster reloads than from a closed bolt. (Fig. e-2, B)
The MDR comes with two ambidextrous options for releasing
the magazine.
When on target and ready to fire, rotate the safety selector
switch to “Fire.” (Fig. d-1)
Squeeze the trigger until the rifle fires. Release the trigger so it
resets, and repeat the process until the magazine is empty or
until desired firing is complete.
Note: Upon firing the last round, the empty casing will be retained in the
chute panel until the bolt is sent back into battery, at which time the empty
casing will be ejected. This is normal and not a malfunction.

To unload/clear the MDR, first rotate the fire selector switch to
“Safe” (Fig. f-1)
Remove the magazine by pressing the magazine release
button above the trigger or by pressing the magazine
release down (in front of the magazine well) and pull the
magazine downward until it clears the rifle. (Fig. f-2)
Pull the charging handle quickly to the rear and release
multiple times to clear any remaining cartridge(s). Pull the
charging handle rearward quickly to reliably eject non-fired
cartridges from the rifle. Ejecting them slowly can cause
malfunctions as they enter the ejection chute. (Fig. f-3)
Pull the charging handle back slowly and view the chamber
check window to ensure and confirm there’s no cartridge still in
the chamber. (Fig. f-4)
