THEORY OF OPERATION
1. Squeeze the trigger to release the hammer. The hammer strikes the firing pin,
which strikes the primer and ignites the propellant.
2. Gases from the burning propellant push the projectile through the barrel of the
weapon.
4. When round reaches approximate end of barrel, expanding gases from the
burning propellant pass through gas port, gas tube and into the bolt carrier
assembly forcing it to the rear. This causes the bolt to extract and eject the spent
cartridge case and chamber a new round.

WARNING
NOTE
When switching to BURST during fire, or changing magazine
while firing in BURST, weapon may only fire 1 or 2 rounds on
first trigger pull. The next trigger pull should fire 3 rounds.
NOTE
If the trigger is released before all three rounds have fired, the
next pull of the trigger will only fire the one or two shots not
fired in the previous trigger pull. A one or two shot BURST
can also happen if firing is continued after changing
magazines or switching from SEMI to BURST.
Follow these steps to ensure weapon fires 3 rounds on first trigger pull:
5. Let go of trigger.

If weapon stops firing with a live round in the chamber of a hot barrel,
remove the round quickly. However, if you cannot remove it within 10
seconds, remove magazine and wait 15 minutes with the weapon
pointed in a safe direction. This will avoid injury during possible
cookoff. ALWAYS keep face away from the ejection port when
clearing a hot chamber.

1. Apply a light coat of Lubricating Oil for Arctic Weapons (LAW) to all
functional parts.
9. Use muzzle cap, protective magazine bag, and weapon cover to protect
weapon in extreme cold weather whenever the tactical situation permits.
10. Field maintenance should remove trigger guard for extended operations
in extreme cold weather.

Hot, Wet Climate – Jungle
NOTE
Use magazine bag, muzzle cap or rifle cover for protection when the
tactical situation permits.
3. Inspect all parts of the weapon for corrosion more frequently and more
completely than normal.
4. Remove handprints from weapon with dry rag and lubricate lightly with
CLP.
NOTE
Deserts are usually areas containing blowing sand and fine dust.
Deserts can be hot during daylight hours and cold during the night.
The harsh environment will severely tax weapons and other
equipment. Consistent operation of weapons depends on following
detailed cleaning and lubricating procedures outlined in PMCS table.
Use magazine bag, muzzle cap or rifle cover for protection when the
tactical situation permits.
0007 00-3
TM 9-1005-319-10 0007
1. Clean inside and functional areas of the weapon every day and after
firing missions in desert environments. Dust and sand will get into the
weapon and magazines and cause malfunctions.
3. Keep the bolt and ejection port cover closed, magazine in the
magazine well, and muzzle cap on to keep sand and dust out of the
weapon.
NOTE
Use magazine bag, muzzle cap or rifle cover for protection when the
tactical situation permits.
3. ALWAYS drain water from barrel before firing. Dry the bore with a
swab and cleaning rod if wet.

After Water Crossing
WARNING
4. Release charging handle and tap forward assist to seat round and lock

NOTE
Slow is defined as ¼ to ½ the normal rate of trigger release.
b. SEMI: Place selector lever on SEMI. Pull trigger. Hammer should fall.
Hold trigger to the rear and charge the weapon. Release the trigger with

trigger to the rear, and cock the weapon again. Fully release the trigger
then squeeze the trigger again. The hammer should not fall because it
should have fallen when the bolt was allowed to move forward during the

25 METER ZEROING
INITIAL SETUP:
Not Applicable
(0-200 meters)
1. The front sight past and rear windage knob are adjusted so you can hit
your point of aim at 300 meters.
3. The 300-meter mark is aligned with the mark on the left side of the
receiver. This will read 8/3 for the M16A2/M16A3 and 6/3 for the
M4/M4A1/M16A4.
0009 00-1
TM 9-1005-319-10 0009
1. During zeroing procedures, only the front sight post and windage knob
are adjusted to move the strike of the bullet on the target.
2. If you are zeroing on a 25-meter range, the rear sight elevation knob is
adjusted in accordance to whichever weapon you are using.
3. Detailed zeroing procedures are on the target and the following pages.
Front Sight – The front sight post is moved up or down when zeroing the
weapon. Once the weapon is zeroed, the front sight post should NOT
be moved.
0009 00-2
FOR ELEVATION (per click)
Do not center rear sight aperture for inspections. Keep your correct
battlesight zero windage on your weapon at all times.
NOTE
DO NOT move front sight post at this time. It was set at the factory or
by a previous shooter and should be very close to your zero.
Center the rear sight aperture by turning the windage knob left or right.
(This is called mechanical zero windage.)
0009 00-3
TM 9-1005-319-10 0009
NOTE
Take weapon to field maintenance if rear sight elevation does not line
up with mechanical zero. 8/3 on the M16A2/M16A3 or 6/3 on the
M16A4/M4/M4A1.
4. Rotate the elevation knob clockwise one click up past the mechanical
zero setting for the M16A2/M16A3 and two clicks up for the M16A4. The
M4/M4A1 carbine should stay at the mechanical zero. Any further
corrections required in elevation are made to the front sight post only.
5. Aim at target center. Adjust front sight and rear windage to move shot
group center as close as possible to the white dot in the center of target.
6. If your shot group is not in the center of the bull’s eye, use the squares
on the target sheet to calculate the required “clicks necessary to move
you next shot group into the bull’s eye. Remember, any changes in
elevation are made by moving the front sight post. The squares are
numbered around the edges of the target to equal the number of clicks
required to move the shot group to the bull’s eye.
7. In order to raise you next shot group, rotate the front sight post
clockwise. One click will move the strike of the bullet one vertical square
on the target sheet. In order to lower your next shot group, rotate the
front sight post counterclockwise, one click equals one square. Changes
in windage are made with the windage knob. Three clicks will move the
strike of the bullet one horizontal square on the target sheet. In order to
move the shot group to the left, turn the windage knob counterclockwise.
In order to the shot group to the right, turn the windage knob clockwise.
8. Carefully aim and fire another group at the center of the target bull’s
eye.
RIFLES ONLY
11. Rotate the rear sight elevation knob counterclockwise, down, one
click to the 300-meter setting for the M16A2/M16A3 Rifle, down two
clicks to the 300-meter setting for the M16A4 Rifle. The weapon is
zeroed for 300 meters.
