forward assist
If the forward assist won’t
budge, you may not be able
to lock the bolt forward.
Squirt one shot of CLP in the
forward assist port inside
the upper receiver. Run the
forward assist back and forth
until it moves smoothly.
magazine
No matter how well you’ve taken care of your M16 or M4, you won’t be doing much
firing if your magazines are in bad shape. Take each magazine apart. But be careful not to
separate the spring from the follower. If they come apart, you will need a new magazine.
Wipe off dirt from the spring and
follower. Lightly lube the spring.
Eyeball all seven magazines for
dents, corrosion or bent feed lips.
While loading, don’t jam the feed lips
against anything hard. That bends lips.
Never try to stretch the spring to
make it work better. That just ruins
the spring.
If you’re not on the battlefield, don’t
leave magazines fully loaded all the
time. That wears out the springs.
Don’t
disassemble the lower receiver and
trigger assembly for better cleaning!
That enlarges the receiver pin holes and they can’t hold
the pins. If the trigger assembly is reassembled wrong,
the M16/M4 fires in the automatic mode when it’s not
supposed to.
Don’t
remove the buttstock to clean
the lower receiver extension!
That causes takedown pin
spring problems and your M16/M4
can come apart during firing.
