ome of the M240B machine guns used on the M153 CROWS II (common remotely
operated weapons station) have a new charging handle. But to use the new charging
handle with CROWS II requires an adapter.
Weapons conFgured with the older charging handle can be used with CROWS II
without the adapter. Look at the picture on Page 39 to see which charging handle your
M240B uses.
The adapter has been issued to most affected units. The adapter comes with NSN
5340-01-578-0847 (PN 13021845, CAGE 19200). If your unit hasn’t received it,
contact the CROWS II item manager, Catherine Boultinghouse, at DSN 786-1363,
(586) 282-1363, or email:
catherine.j.boultinghouse.civ@mail.mil
To install the adapter, you need a 3mm hex-head wrench and a 7mm nut driver.
The hex-head wrench is part of the CROWS II operator’s tool kit.
The nut driver is being added to the tool kit. You can get a nut driver and the two
attaching screws and lock nuts from your local CROWS II new equipment training
team (NET) representative, the local CROWS II support group (CROWS Nest), your
TACOM LAR or by ordering:
•±
Nut driver,
•±
2 screws, hex-head socket,

Dear Half-Mast,
TM 9-1005-201-23&P says that to store M249s with a short
buttstock in the M13 rack, you need two different adaptors. But the TM
doesn’t tell you how to get the adaptors. Do they have NSNs?
Mr. P.R
Dear Mr. P.R.,
The April 2013 edition of the TM does include these NSNs.
To secure an M249 with a collapsible buttstock in the M13
rack, you need mounting bracket, NSN 1005-01-606-2583, and
storage rack adaptor, NSN 1005-01-606-1875.
If your unit needs the mounting bracket and rack adapter,
contact TACOM’s Jasmine Davis at DSN 786-1254, (586) 282-
1254 or email:
jasmine.a.davis22.civ@mail.mil
or Jill Gibson at DSN 786-1653, (586) 282-1653, or email:
jill.a.gibson4.civ@mail.mil
TACOM will send you the bracket and adapter as free issue.
