Dear Sergeant J.B.
Here’s the scoop.
Because the original axle used on the semitrailer is no longer available, you’ll
have to use axle, NSN 2520-01-499-5403, that’s used on the M871A3 22-ton
flatbed semitrailer.
However, the -5403 axle uses different rims, so you’ll need 4 rims, NSN 2530-
01-441-9700, for each new axle.
It’s the same rim used on the M915-series trac-
tor trucks, so you can use the truck’s spare if you get a flat on the new axle.
Use tire, NSN 2610-01-045-3688, on both rims.
As long as you have any of the original axles on the trailer, use rim 2530-01-
290-5715 for the trailer’s spare.
That way, you’ll have a spare for the original
axles.
If you’ve had to replace all the axles on the semitrailer with the new axles,
be sure to change the trailer spare to the -9700 rim.
Do not use
NSN 1005-01-083-
8113 to order a sling
for an M16 rifle or M4
carbine. Your order will be
rejected by DSC-Columbus.
NSN
1005-00-
050-6357
now
brings a box of 25
cleaning rod sections
instead of just one as it
used to. The cleaning rod sec-
tion is used with the M16 rifle,
M4 carbine, and M231 and
M249 machine guns.

No Unauthorized Weapons
Modifications Allowed
Reports are coming in that soldiers are modifying their rifles, pistols, and machine guns
to try to improve how they work or to make them easier to handle in combat.
That’s a big
no-no!
The only time a weapon can be modified is if the Army has approved a modifica-
tion work order (MWO).
Para 3-1e in AR 750-10,
Army Modification Program,
makes this very clear:
“Commanders will not allow their equipment to be modified unless there is an official
MWO.”
If you modify your weapon without authorization, you risk making it non-mission
capable and you can be held responsible for any damage to it or to your fellow soldiers.
Dear Half-Mast,
Is there a good NSN for the axle on my unit’s M872-series 34-ton
flatbed trailer? Using the parts info in TM 9-2330-359-14&P gets
you nowhere.
