What
Not
To Do
Don’t take apart the trigger assembly.
You’re not trained to
do that. If the trigger assembly is put back together wrong–and
it’s easy to do it wrong–you could have a runaway weapon. To
make sure the trigger is working right, it’s a good idea to do the
function test in WP 0008 of TM 9-1005-319-10 before you Fre.
Don’t substitute paper towels or old rags for cleaning
patches and new cleaning rags.
They shred and clog areas like
the buffer tube.
Don’t use the Fring pin for cleaning.
That blunts the Fring
pin’s tip, which means it probably won’t ignite the cartridge.
Don’t use oven or carburetor cleaner or cleaning pads.
They clean so well they take the weapon’s Fnish right off.
Don’t remove the buttstock to clean the lower receiver extension.
If you
damage the takedown pin spring, your M16/M4 could come apart during Fring.
Don’t use cotton-tipped swabs.
The cotton comes off and plugs things like the
carrier key.
Don’t use homemade cleaning tools.
They scratch off the protective Fnish.
Don’t remove the self-locking screw in the buttstock.
Once the screw is out, it’s
no longer self-locking. The buttstock can turn while you’re Fring.
Don’t use the bore brush on the outside of your M16/M4.
It will rub the
protective Fnish right off.
Don’t use lightweight oils.
They evaporate quickly and have a low ±ash point.
Every
Soldier runs
into know-
it-alls who
think they
know better
ways to take
care of the
M16/M4.
Don’t listen
to them.
Here’s what
not
to do…
Hands off my
trigger assembly!
if you take it apart,
you’ll never get it
back together again!
Who told
you I was
a cleaning
tool?! Now
my point is
so dull I’ll
never be able
to set off a
cartridge!
YOu calL that a
cleaniNG tOol?
pFft!
LoOks more like
MODern Art!
trust
me…
this new
product,
lub,
is
better
than
CLP!
so how
many would
you like?!
You can stick
that
in your
ear! Cotton-
tiPPed swabs
clog me up!
Do I
look like
a carburetor?
Get
away
from
me!
