Dear Editor,
While trying to help our maintenance folks
order new gages for the M249 machine gun,
we noticed that the NSN for the headspace
gage has changed to 5220-01-141-3830.
It’s Item 6 in Fig C-15 of TM 9-1005-201-
23&P (Dec 90, w/Ch 7, Jun 02). You might
want to let the field know.

Editor’s note:
We just did. Thanks, Doug. Armorers, note that this gage
is a Class II item, so you’ll need to order a new one through unit supply.
A
lightweight collapsible buttstock is replacing the M249 machine gun’s standard
buttstock, the M5 collapsible buttstock and M4 collapsible buttstock through an MWO.
Units don’t need to order the new buttstock, NSN 1005-01-576-8901. It will be installed
free on your M249s through Small Arms Readiness Evaluation Teams (SARET), Total Package
Fielding (TPF), and depot overhaul. Contact your local MWO coordinator for fielding info.
I
f your unit has Fre control devices containing tritium (H3), you need to turn them
in because they pose a radiation danger if not handled properly and leaks develop.
The Fre control devices will be replaced with ones that have been modiFed with
the elimination of radioactive light sources (ERLS) kit.
The devices include the M1A1 collimator, M1A2 Fre control gunners quadrant,
M171 and M187 mount telescope and quadrant, the M137 panoramic telescope,
M138 elbow telescope, M139 and M140 alignment devices, and M17 and M18
quadrant Fre controls.
If you think you have a Fre control device containing tritium, immediately contact
TACOM’s Towed Artillery Core Team at DSN 786-2755 or email:
usarmy.detroit.tacom.mbx.ilsc-fa-core-team@mail.mil
Provide the NSN and quantity of Fre control devices. You will be given disposition
instructions if your devices do indeed contain tritium.
Remember that tritium is a radioactive source and must be handled with care. ±or
info on safe handling, check with your local radiation safety ofFcer (RSO). Shipping
of Fre control devices must be coordinated with the RSO. If you’re not sure who your
RSO is, contact TACOM’s NRC license RSO at DSN 786-0891 or email:
