•±
Depress the follower with your index Fnger.
•±
Grip the base of the magazine tool with
your other hand.
•±
Slide the curved channel of the magazine
tool along the bolt catch cutout area of the
magazine housing.

Apply slight pressure to slide the tool
through the feed lips. If the GO portion
passes through the feed lips freely and the
NO GO portion does not pass through the
feed lips, the magazine is good to go.
Takedown and Pivot Pin
If
the
pins
stick,
you’ll
have
trouble disassembling your weapon.
Put a stripe of CLP down each pin
and work it in and out of the receiver
until it moves easily.
Front Sight Post
If
the
post
sticks,
you
can’t adjust it. That means
you could miss what you’re
shooting at. Clean around
the post with a toothbrush.
Depress the detent and give
it a drop of CLP. Work the
detent and post up and down
until they move smoothly.
Buttstock Drain Hole
If
the
hole’s
plugged,
moisture
collects inside the buttstock and soon
corrosion is chewing up the lower
receiver. Run a pipe cleaner through
the hole.
Windage and Elevation Knobs
If the knobs stick, you can’t adjust the rear sight.
Put a couple of drops of CLP on each knob and turn
the knobs until they move smoothly. Return them
to their original positions.
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’s moving smoothly.

A more reliable
magazine for the
M16 and M4/M4A1
has been available
for several years.
Every arms
room should
have the new
tool for
IDing bad
magazines.

with NSN

0036 and
costs less
than $25.
But if the GO portion won’t pass through
because the feed lips are crushed or
bent inward or the NO GO portion does
pass through because the feed lips are
separated, the magazine is
shot.
Don’t
try to fix
it by bending the
feed lips. Get a
new
magazine.
Here’s how to
use the tool…
it has a
redesigned
follower and a
stronger spring
that provides
greater reliability
and fewer
malfunctions.
You can ID
the new
magazine
by its
tan
follower.
Order it with
NSN 1005-01-

it’s OK to
use the old
magazines
until they
wear out.
Then order
the new one.
