Don’t
remove the compensator
to clean the barrel!
If the compensator is not tightened right
when it’s reinstalled, then it can vibrate
off if it’s too loose. But if it’s screwed on
too tight, the barrel threads are ruined
and so is the barrel.
Once the self-
locking screw
is removed,
it no longer
stays tight and
the buttstock
can turn
during firing.
The visors have guides that ride in tracks. Sand and dirt build up in the tracks and
make raising and lowering the visors difFcult. It can also cause the visors to bind or
jump out of the tracks.
If
you
pull
on
stuck
visors, they will break. Then
your helmet is NMC until
the
ALSE
tech
replaces
broken visors.
To keep visors operating
smoothly, use a little low
pressure air to blow away
dirt, grit and sand. If no air is
available, use a pipe cleaner
to get the gunk out. And
resist the temptation to use
lubricants. They attract dust
and leave a sticky residue.
Don’t
remove the self-locking
screw in the buttstock!
Don’t
use
stuff like oven,
toilet bowl,
carburetor or
kitchen cleaners,
shaving cream
or products
like
