M2 Machine Gun . . .
Bad Latches
B
ad M2 machine gun back plate locking latches
are still out there.
The bad latches bend and warp and let the back
plate slip off. If that happens, your M2 could come
apart during firing. That’s why you armorers need
to check your M2s right now for bad latches.
Bad latches are rounded on the corners. Good
latches are square-cornered, have more metal on the
bottom, and have the part number stamped on them.
If you find a bad latch, get support to replace it.
M2s with the old latches are deadlined until they
get a new latch.

Dear Lieutenant L.B.,
Paint is not the answer. It will not stick to the smooth metal of the tripod.
Whenever bare spots appear on a tripod, you should immediately treat them
with solid film lubricant (SFL), NSN 9150-00-754-0064. That’s the best way to
beat corrosion on the tripod and the machine gun itself.
If you’re part of a rapid deployment or
divisional combat unit, you can touch up
no more than one-third of the tripod with
SFL. If more than one-third of the finish is
gone, you should turn in the tripod. All
other units can touch up the entire tripod.
Clean off any corrosion before applying
SFL.
