Installing Recoil
Amplifier
on
M2A1
Dear Editor,
Page 40 in PS 723 (Feb 13) said that armorers need to keep the
M249’s solid buttstock even if they’ve switched to the new collapsible
buttstock, NSN 1005-01-515-8268. That’s because the collapsible
buttstock is AAL, which means the solid buttstock must be reinstalled if the
M249 is turned in or transferred to another unit.
But that’s not true if the M249 has gone through MWO 9-1005-201-
50-2, which replaces the solid buttstock with the collapsible buttstock.
The collapsible buttstock becomes a component of end item (COEI). In that
case, the solid buttstock should be turned in as directed in the MWO’s
Para 8.
One other point: The short barrel is indeed AAL and should be kept by
the unit when they turn in or transfer an M249. But before the barrel is
used on another M249, it must first be headspaced and tagged to that
weapon. It’s dangerous to fire an M249 with a barrel to which it hasn’t
been headspaced.

Editor’s note:
Excellent points, WO1 Gleason. Thanks for educating us.
The small arms repair instructors in Maintenance Activity Vilseck pointed out
that the M5 shoulder stock, LIN S41357 and NSN 1005-01-411-1264, is now
obsolete. When armorers turn in the M5, they should make sure it’s removed
from their property book. Disposition instructions for the solid buttstock are in
the MWO.
Dear Editor,
Armorers and other small arms repairmen can save time having their gages
gaged. All they need to do is keep the gages sealed in the TMDE bags they
originally came in until the gages are actually needed.
TMDE puts the gages in sealed bags to protect them from dust, corrosion
and wear. If the gage hasn’t been used (as in the case of duplicate gages)
by the time it’s due for the next TMDE inspection and is still in its sealed
bag, TMDE can immediately extend the life of the calibration.
Unused gages must be in their sealed bags, show no damage and have a
completed DA Form 3023,
Gage Record,
with them. Up to two calibration
extensions are allowed. For more information, see TB 9-5220-215-24, TB
750-25 or contact your local TMDE Support Activity.

Thanks for the time-
saving info, Gary.
H
ow do you install the M3 recoil amplifier on the new M2A1 machine gun? Just like you
did on the M2 machine gun.
If you need the procedure, check out the M3’s TM 9-1005-203-13&P. The TM is being
updated to include the M2A1, but the procedure stays the same.
The TM is on the LOGSA ETM website:

Until
Needed
I hear they’re
transferring you
to another unit.
I guess they’ll have
to put your standard
buttstock back on?
no, I went
through the
mwo.
I keep the
collapsible
buttstock
from now on.
it’s
permanently
a part of
me!
How are you
installed on
me?
don’t take me out of this
bag unless you
really
need to use mE!
I haven’t
been used
since I
was last
calibrated,
so that
means I
can get a
calibration
extension by
staying in
this bag!
same way I
was on the
old
M2!
