DESTRUCTION NOTICE - Destroy by any method that will prevent disdosure of
contents or reconstruction of the document.
WARNING
Before starting an inspection, be sure to clear the weapon. Do not
squeeze the trigger until the weapon has been cleared. Inspect the
chamber to ensure that it is empty and no ammunition is in position to
be chambered. Do not keep live ammunition near work area.
Use only blank M200 with the BFA and DO NOT fire directly at anyone
less than 20 feet away.
To be considered SAFE before disassembly, cleaning, inspecting,
transporting, or storing, the weapon must be cleared.
With the bolt carrier assembly locked to the rear or in its forward position,
if the weapon is dropped or jarred with a loaded magazine in place, it
could chamber a round.
When your weapon is loaded, ensure it is pointed in a safe direction.
Do not load with a hot chamber.
a
WARNING (Cont)
If your weapon stops firing with a live round in the chamber of a hot
barrel, remove the round fast. However, if you cannot remove it within
10 seconds, remove magazine and wait 15 minutes with the weapon
pointing in a safe direction. This way you won’t get hurt by possible
round cooking off. Regardless, keep your face away from the ejection
port while clearing a hot chamber.
DON'T OVERHEAT BARRELS. Sustained firing of the weapon will rapidly
raise the temperature of the barrel to a critical point
Firing 140 rounds, rapidly and continuously, will raise the temperature
of the barrel to the COOKOFF POINT. At this temperature, any live
round remaining in the chamber for any reason may cook off (detonate)
in as short a period as 10 seconds.
If the cookoff point (or temperature) is felt possible, weapon should be
immediately cleared and allowed to cool.
Sustained rate of fire for the weapon is 12-15 rounds per minute. This
is the actual rate of fire that a weapon can continue to deliver for an
indefinite length of time without serious overheating.
b
WARNING (Cont)
Sustained rate of fire should never be exceeded except under
circumstances of extreme urgency.
Exceeding the sustained rate of fire can result in a catastrophic failure
of the barrel and injury or death to personnel.
When disassembling, turn magazine away from face, spring is under
compression.
If an audible ‘POP’ or reduced RECOIL is experienced during firing,
immediately CEASE FIRE. Either condition could indicate an
incomplete powder bum and/or a bullet stuck in the bore.
Do not fire if water is present in barrel.
DO NOT interchange bolts between weapons.
Be sure the cam pin is installed in the bolt group. If it isn’t, your weapon
can still fire and will explode.
c
WARNING (Cont)
DO NOT FIRE:
Seriously corroded ammunition.
Dented cartridges.
Cartridges with loose bullets.
cartridges exposed to extreme heat (135°) until they have cooled.
Cartridges with the bullet pushed in (short rounds).
Make sure your weapon is clear and on SAFE before moving down
range.

3. Face the target, place the weapon to your shoulder, move the selector lever
from SAFE to SEMI or AUTO/BURST.
4. Aline the front and rear sight with the target and squeeze the trigger.
5. Squeezing the trigger releases the hammer, which strikes the firing pin,
causing it to impact the primer of the round.
6. The primer ignites the propellant in the round.
0004 00-0
7. Gas from the burning propellant pushes the projectile along the barrel of the
weapon.
8. The rifling in the barrel causes the projectile to rotate which provides stability
during flight to the target.
9. 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.

To remember your correct battlesight zero windage, note location of windage
scale and windage knob pointer (heavy mark on outside of knob).
Do not center rear sight aperture for inspections. Keep your correct bat&sight
zero windage on your weapon at all times.
By following the steps below and establishing a zero at 25 meters, your sights
will be set with a 300-meter battlesight.
NOTE
Do not move front sight post at this time. lt 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.)
0011 00-6
1. Position a 25 Meter Zero Target; NSN 6920-01-395-2949, 25 meters from the
firing line. The rifle target is on one side and the carbine target on the other.
2. The unmarked long range aperture should be up.
3. Rotate elevation knob in the down direction (counter-clockwise). The elevation knob should stop on the 300-meter mark (8/3) M16A2/M16A3 rifles and
(6/3) M16A4/M4/M4A. The rear sight should be all the way down on the last
whole "click" before it bottoms out. This is called mechanical zero elevation
for the rear sight If your range scale will not line up in the above manner, an
armor will be required to adjust the range scale for you.
4. Now rotate the elevation knob clockwise (up) one click past the 300 meter
setting for the M16A2/M16A3 rifle, clockwise (up) two clicks for the M16A4
rifle. The elevation knob should remain aligned on the 300 meter setting for
the M4/M4A1 carbine. Any further corrections required in elevation are made
to the front sight post only.

the target sheet to calculate the required "clicks" necessary to move your
next shot group into the bull’s-eye. (Remember that 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 your 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, as above, 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
move 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.
9. Repeat Steps 6 through 8, if required.

WARNING
Before cleaning be sure to clear the weapon.
GENERAL
NOTE
Wherever the term CLP or the words lube or lubricant are cited in this
TM, it is to be interpreted to mean that CLP, LSA, or LAW can be
utilized as applicable. DO NOT mix lubricants on the same weapon.
The weapon must be thoroughly cleaned during change from one
lubricant to another. Dry cleaning solvent (SD) is recommended for
cleaning during change from one lubricant to another.
1. With the weapon disassembled, thoroughly clean, inspect, and lube.
2. Always shake CLP before use.
3. After firing, clean your weapon according to instructions. Wipe dry and lube
according to lubrication instructions (WP 0016 00).

GENERAL (Cont)
4. Cleaning materials (swabs, pipe cleaners, and CLP) are expendable items
that are available from supply.
CAUTION
Don't mix up the parts of your weapon with those of your buddy.
BORE
The bore of your weapon has lands and grooves called rifling. Rifling makes the
bullet spin very fast as it moves down the bore and down range. Because it
twists so quickly, it is difficult to push a new, stiff bore brush through the bore.
You will find it easier to pull your bore brush through the bore. Also, because
the brush will clean better if the bristles follow the grooves (called tracking), you
want the bore brush to be allowed to turn as you pull it through.
0014 00-2
This is how you do it:
1. Attach three rod sections together.
2. Swab out the bore with a patch
moistened with CLP or rifle bore
cleaner (RBC).
3. Attach the bore brush. When using
bore brush, don’t reverse direction
while in bore.

4. Point muzzle down. Hold the upper receiver in
one hand while inserting the end of the rod without
the brush into the chamber. Let the rod fall straight
through the bore. About 2-3 inches will be sticking
out of the muzzle at this point.
5. Attach the handle section of the cleaning rod to
the end of the rod sticking out of the muzzle.
6. Pull the brush through the bore and out the
muzzle.
7. After one pull, take off the handle section and
repeat the process.

8. Send a patch through the bore once in a while to help clean out the crud
that the brush is getting loose. Replace the bore brush with the rod tip (patch
holder) and a wet patch. Drop it through. You won’t need to attach the
handle to pull only a patch through.
