When you think you have all the wax cleaned out of the barrel, run your cleaning
rod from muzzle to chamber to make sure there are no obstructions. Look for the end
of the cleaning rod in the chamber.
If you can’t see the end of the rod, you may have a stuck round. If you can’t push
out the round yourself, tell your armorer. But make sure the problem is Fxed before
you turn in the weapon to the arms room.
T
he good news is the close combat mission capability kit (CCMCK) is approved
for not only the M16 ri±e and M4 carbine, but also the M249 machine gun and M9
pistol. CCMCK gives you a safe, reliable, and accurate training system that closely
mimics Fring real rounds.
The bad news is the wax from CCMCK rounds can leave the inside of your
weapon a mess. If you don’t do a good job cleaning out all the wax, it can plug the
barrel. ²iring a weapon with a plugged barrel is dangerous to you and your weapon.
Avoid that potential catastrophe with this CCMCK PMCS:
BEFORE–
Clean and lube your weapon with CLP like it’s spelled out in the
weapon’s -10 TM. You want your weapon as clean as possible before Fring
CCMCK rounds.
AFTER–
Do the same cleaning and lubing procedure, but this time pay
special attention to the chamber, barrel and bore. Those are the most likely areas
you’ll Fnd wax. Really tough wax deposits may require dry cleaning solvent,
NSN 6850-01-474-2319. Use solvent under the direction of your armorer. The
solvent may need to soak into the wax for several minutes before it will work.
M151 Scope NSN Changes
Because of safety concerns, you can no longer order the M151 scope with NSN 6650-01-504-
8456, which brought the scope alone. Instead, use NSN 6650-01-557-7444. That brings the
scope and the laser filter unit (LFU). The LFU ensures your eyes will be protected from lasers.
Armorers, don’t use a new M16/M4 barrel that
has Fred fewer than 200 standard rounds for CCMCK.
Older barrels are less likely to have problems with
a stuck CCMCK round. M249 barrels come from
the
manufacturer
ready
for
CCMCK
Fring.
The
M9 conversion kit has a blue barrel for Fring CCMCK
rounds.
After training with CCMCK, it’s a good idea to
check the M16s and M4s with the barrel straightness
gage. See WP 0015-24 in TM 9-1005-319-23&P.
²or the complete word on CCMCK, see TM 9-6920-
3700-10. It’s on the LOGSA ETM website:
