A
ll M249 machine guns should have been modified by now with MWOs 9-1005-201-50-1
and 9-1005-201-30-6.
MWO
9-1005-201-50-1
added
an
accessory mounting rail to the feed
tray cover. That enabled Soldiers to
mount the AN/PEQ-2A and AN/PAQ-4B/C
laser
pointer/illuminators,
AN/PAS-13
thermal weapon sight, AN/PVS-4 night
vision sight, M145 machine gun optic,
and combat identification system for
dismounted Soldiers (CISDS).
MWO 9-1005-201-30-6 replaced the
hand guard with a forward rail assembly,
which
provides
a
second
rail
for
mounting optical and electronic devices.
These MWOs have passed their
completion date, so there is no
longer MWO funding or assets for
them. If your M249s haven’t been
modified, you will need to order
the MWO parts through normal
supply channels. The top cover is
NSN 1005-01-547-2614. For the
forward rails, order right accessory
rail, NSN 1005-01-559-1947; left
accessory rail, NSN 1005-01-559-
1948; and socket head cap screw,
Armorers, if any of your M249s have received
these modifications, TACOM wants to know about
it so they can update the serial numbers in the
MMIS tracking system. Call DSN 793-1348/6539/7458
or (309) 782-1348/6539/7458. Or email:
john.delmonico@us.army.mil
or
gary.p.nellis@us.army.mil
or
andre.pilgrim@us.army.mil
If your M249s have been modified, make sure
their serial numbers have been reported through
your local PBO/MWO coordinator, too.
Dear Editor,
Here at the small arms support shop at Ft Hood, we continually run into
armorers who don’t have the two required standard barrels for their M249
machine guns.
When their M249s go through SARET repair, the standard long barrel
is sometimes replaced with a short barrel. Or armorers order a short barrel
and turn in a long barrel.
As you pointed out in PS 689 (Apr 10), the two standard barrels are BII
(basic issue items), which means they must be kept at all times. The short
barrel, on the other hand, is AAL (additional authorization list), which means
it’s authorized but optional. You don’t have to have it.
But what PS 689 didn’t point out is that the standard barrels have
a controlled inventory item code of 4, so the barrels do have security
requirements. If a standard barrel is missing, AR 190-11,
Physical Security
of Arms, Ammunition, and Explosives,
states the commander can initiate
an investigation.
No armorer needs that grief. So never ever be without both M249
standard barrels, regardless of how many short barrels you have. Order a
new long barrel through your support, if necessary.
