ome of the M240B machine gun used on 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 don’t need the new adapter
and can be used with CROWS II without the adapter. Look at the picture on the next
page to see which charging handle your M240B uses.
The adapter has been free-issued already to most affected units. The adapter (PN
13021845 and CAGE 19200) comes with NSN 5340-01-578-0847. If your unit
hasn’t received it, contact the CROWS II item manager, Charlie McIntyre, at DSN
793-7389, (309) 782-7389, or email
charlie.mcintyre@us.army.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 (NETT) representative, the local CROWS II support group (CROWS Nest), or
from your TACOM-RI LAR.

f you’re not sure what to do with unwanted munitions, you need to consult MIDAS.
The Munitions Items Disposition Action System (MIDAS) was created by the US
Army Defense Ammunition Center to provide a database of demilitarization and
disposition information for unwanted munition items.
MIDAS offers these features:
Databases—
Databases of munitions and their components that aid searches for
munition materials, parts, and components to end items
Munition images—
Diagram views of some munitions
Existing capabilities—
Databases of which installations can do recovery and
recycling of munitions
Firing point/impact point—
IdentiFcation of materials that remain at the Fring
point or are released at impact. This information is essential for environmental range
assessments.
To access MIDAS online you will need to register for a user ID and password. The
MIDAS website URL is:

Some of the Frst adapters sent to the Feld had the wrong SAE 8-32 attaching
screws. Replace them with the metric hardware listed with the nut driver.
