MK 19 Machine Gun…
L
ots of units who have deployed have shipped out their MK 19 machine guns with-
out the feed throat assemblies. It's easy to forget the feed throat assembly because
it's usually stored separately in the arms room from the rest of the gun.
But without the
assembly, your MK
19s will have firing
stoppages. So when
you ship out your
MK 19s, make sure
you're also shipping
out the feed throat
assemblies too.
I
f you don't catch MK93 mount catch bag problems on your MK 19 machine gun,
they will catch you during firing.
A catch bag that's installed wrong or
is not emptied of spent cartridge cases
lets cases pile up under the bolt. That
makes it difficult for the bolt to move
and the firing pin hits the next cartridge
before it's fully chambered. The car-
tridge case ruptures and the projectile
doesn't make it out of the barrel. The
next round can blow up the barrel.
Make sure the catch bag is installed
correctly. Keep an eye on the bag during
firing. Empty it when it’s almost full.
MK64
Mounts
Modified?
MWO
9-1010-231-30-2 (Mar 98) modified the MK64 machine gun mount from
Mod 7 (NSN 1010-01-179-7616) to Mod 9 (NSN 1010-01-412-3159). All units
should have had the MWO done to their MK64s by now. Unfortunately, that's not the
case and units are trying to order parts for the Mod 7 that are no longer available.
Units should immediately check to see if their MK64s have been modified to
Mod 9 and that their property books show the change. Mod 9s use the universal pin-
tle adapter and the larger catch bag with the velcro side. If your mounts haven't been
modified, TACOM Rock-Island still has a limited number of the MWO kits available.
