Help with cleaning.
The chamber is the
worst carbon collector. If you don’t get out
all the carbon, the chamber will become
pitted and the barrel eventually will have
to be replaced.
To clean the chamber, soak your bore
brush in RBC and run it through the muzzle
into the chamber. Do this again and again
until the brush stops pulling out carbon.
If you can’t clean out all the
carbon, your armorer is authorized
to use dry cleaning solvent. But
he needs to be careful not to dip
the bolt, ogive plunger, or sear
in
solvent.
They
have
sealed
components with grease inside.
Instead, clean these parts with a
rag or brush dipped in solvent.
Dear Editor,
Pages 50-53 in PS 721 (Dec 12)
listed all the new parts available for the
M240-series machine guns. But you
neglected to mention that the M240B
adjustable bipod assembly will be
provided free through MWO 9-1005-
313-50-3. Units don’t need to order
these parts. They can check with the
local MWO coordinator to find out when
their M240Bs will be converted.

Editor’s note:
The MWO will be done by
SARET or at depot. Armorers need to keep
a copy of the adjustable bipod NSNs until
they are added to TM 9-1005-313-23&P.
When doing conFdence checks, do them in an environment with as little air
movement as possible. That means seeking protection from wind if you’re outside
and turning off fans inside. The stiller the air, the easier it is for the JCAD to read
the sample.
Remember that
once you take a
conFdence sample
out of its sealed
bag, its service life
is 1-2 years tops.
If JCAD is having
trouble reading a
sample, it may be
because the sample
is old and needs to
be replaced.
