MK19 Machine Gun…
Dear Half-Mast,
I think there are too many
armorers who don't have all the
special tools needed to work on
the MK19 machine gun. It would
help if you would put a list of
the special tools and their
NSNs in PS so armorers would
know what they're missing.

MK19 Machine Gun…
I
f the MK19 machine gun drive levers can't move ammo forward, it comes to a dead
stop on firing. Keep the drive levers on the move with these points:
•
MWO 9-1010-230-50-1 replaces the sec-
ondary drive with an adjustable lever. But
you must be careful how you remove the
new lever. If you use a hammer to knock it
out of the top cover assembly, you could
damage the area in the cap screw where the
hex head fits. Then you may have to replace
the cap screw because it will create adjust-
ment and disassembly problems.
Use a small rubber mallet or block of
wood to push out the lever or gently pry
it off on the bottom of the cover with the
MK19 wrench.
•
Once the MWO has been applied, you can't switch levers between MK19s. Each
machine gun's lever has been adjusted to that particular gun. A different lever may
put rounds in the wrong position, which causes jamming.
•
When you put the secondary drive
lever back together, make sure its washer
is centered. If you put it on upside down,
the washer is off-center and the second-
ary drive lever assembly will be difficult
to install. And if you do get it in, it will be
difficult to remove the drive lever later.
