Dear Mr. T.W.,
TB 43-180,
Calibration and Repair Requirements for the Maintenance of Army
Materiel,
is the word on calibration of small arms gages. It’s on EM 0022, the CD
that contains most of the TMDE regs.
Small arms gages must be
calibrated every 360 days,
regardless of whether your unit
is Active, Guard, or Reserve. The
calibration can be done only by
one of the Fve TMDE labs.
If you have any questions about small arms gages, contact TACOM-Rock
Island’s Kevin Moore at DSN 793-2359/(309) 782-2359 or email:

ow much of the M2 machine gun’s Fnish can be missing before the weapon must
be turned in to depot? If you look that up in the M2’s TM 9-1005-213-23&P, the
answer is more than one-third of the M2’s surface.
But
that criteria is for peacetime. In extended combat operations like Iraq, the M2
doesn’t need to be turned in, no matter how much of its Fnish has worn off. As long
as the M2 is fully functional, you can keep Fring it.
But you do need to touch up those shiny spots with solid Flm lubricant (S±L),
NSN 9150-01-260-2534, to prevent corrosion and to keep light from reflecting off
the weapon and pinpointing your position to the enemy.
Armorers, before applying S±L, Frst clean the shiny areas
with dry cleaning solvent. The solvent gets rid of all lubricant
in the metal. Lubricant prevents S±L from sticking to the
weapon, so soon you’ll have a shiny spot again.
After cleaning with solvent, let it dry completely.
Then apply the S±L and let it dry for 12 hours. Then
re-lube the weapon. You’re done.
Dear Half-Mast,
We’ve been using our headspacing and timing gages for our M2, M3, and
M296 machine guns for years. After all this time, we’re wondering how
accurate these gages are. But we can’t find anything in the TMs about how
often the gages should be calibrated. What should we do?

finish is
gone!
guess I’ll
have to turn
you in.
wrong, charlie.
since there’s a war
going on, you can
just touch me up
with sfl and I can
keep firing.
Gages must
be calibrated
every 360 days
are you
sure
these gages are
still accurate?
they
look
pretty
beat up!
we haven’t been
feeling very
sharp lately.
better
