efective buffers for the M240B/M240L machine guns have gotten out in the Feld.
The buffers, NSN 1005-01-461-0326, have bad hydraulic ±uid Fll plug screws that
can loosen during Fring. The buffer’s hydraulic ±uid then leaks out, which means the
buffer can’t do its job. That can lead to a ruined receiver.
The 9,000 M240B/M240Ls possibly affected are listed by serial number in
tacom_wn/M240BBufferRecallSNs.xls
Armorers, if you have
any
M240B/M240Ls

check for the bad buffers,
which are stamped with an
ID code date of January
2010 to June 2011.
They should disassemble the buttstock assembly and check if its buffer is within
the date range. If the buffer has no date stamped on it or the date isn’t January 2010
to June 2011, the buffer is good to go as long as it doesn’t show signs of leakage. If
the buffer is within those dates but has R stamped on it, it has been reworked and is
also OK to use.
But if the buffer is in the date range and has no R, it must be replaced. Deployed
units can have the buffer replaced at the nearest small arms repair facility.
Non-deployed units must submit a PQDR to get a new buffer. If the buffer
has a CAGE code of IH²X2 (Kaeper Machine), the PQDR must be submitted to
DLA online:
The CAGE code is stamped on the buffer.

he Reset/repair program for smoke grenade
launchers has halted because they have run out
of launchers. Any of the following launchers that
are not being used or are not working should be
turned in immediately:
Smoke grenade launchers in condition codes
F
or
H
should be sent to:
For launchers in all other condition codes,
contact Ramon Perez for mailing instructions at
DSN 786-1553, (586) 282-1553, or email:
ramon.j.perez.civ@mail.mil
Units should send the launchers via military
shipping at their own cost. No credit will be
given to the units for the launchers.

Rework mark R MM/YY
Original mark MM/YY
Check buffer for
dates January 2010

R means the buffer
has been reworked
and is OK to use
I guess
this
explains why you’re
not well. you have a
defective
buffer.
good going! now I have
a ruined
receiver,
too!
if you
had only
checked
my buffer
before
you
fired me,
I’d be fine.
hey guy, the reset/repair
program has
no
smoke
grenade launchers and they
need
to work on them.
so since I’ve been here
a while and I’m not going
anywhere anytime soon…
…send
these
things in
now!
