Dear Editor,
The purging valve caps for the TOW
missile's AN/TAS-4D night sight
often disappear or get cracked. Then
dirt gets in the valve and makes it
difficult to purge the sight. Since the
cap doesn't have an NSN, units must
order a whole new purging valve
assembly just to replace the cap.
That costs more than $200.
A cheap substitute for the cap is
the HMWWV's tire valve cap. Your
motor pool should have plenty of
them. If it doesn't, you can get 100
caps for less than $2 with NSN

Dear Half-Mast,
MWO 9-1005-245-20-1 converted our M122 tripods to
M122A1s by replacing the flexible mount with a fork assembly
and pintle assembly so that it could be used with the M240B
machine gun. Our problem is that we need a new fork assembly
and we can't find an NSN for it. Can you help?
SPC M.D.
Dear Specialist M.D.,
You bet.
Actually, there are four parts for the fork assembly:
A tip of the cap for your money-
saving tip. Thanks.

HEY!
I'm in a
fog here!
If you hadn't
let all that
dirt plug my
purge valve,
you could be
seeing clearly
now!
The other parts needed for the
MWO are the pintle, NSN 1005-
01-461-2656, and two rings,
If you have the M240B, your
M122s should have been con-
verted to M122A1s.
If they
haven't been, contact TACOM-
Rock Island's Kathy Johnston at
(309) 782-7338/DSN 793-7338
or e-mail
johnstonk@ria.army.mil
.
She can help you get the MWO,
which can be done by you
armorers.
