WARNING
To avoid accidental firing, BE SURE WEAPON IS CLEAR. Failure to do so could result in serious injury or death.
Be sure the cam pin is installed in the bolt group. If it isn’t, your rifle can still fire and will explode causing injury or death.
DO NOT exchange or switch bolt assemblies from one AR-15 to another. It could cause damage to both you and your rifle.
DON’T OVERHEAT YOUR AR-15 BARREL. Sustained firing of the AR-15 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 chamber for any reason may detonate
If the Sustained rate of fire for the AR-15 is 12-15 rounds per minute. This is the actual
rate of fire that this weapon can continue to deliver for an indefinite length of time without seriously overheating.
Sustained rate of fire should never be exceeded except under circumstances of extreme urgency.
If your bolt fails to unlock and you try to free it by banging the buttstock on the ground, keep clear of the muzzle.
If there’s water in the barrel, don’t fire the rifle. It could explode. If you experience a noticeable difference in sound or recoil, STOP FIRING. Either
condition could indicate an incomplete propellant bum and a bullet still in the bore. Retract bolt slowly and remove fired cartridge case. Clear weapon and check for unburned powder grains in the receiver or bore, and for a bullet in the bore. Remove unburned propellant or bullet from bore before resuming firing or barrel could explode. If bullet is lodged in bore, take your rifle to a qualified gunsmith.
If your rifle stops firing with a live round in the chamber of a hot barrel, remove the round quickly. If you cannot remove the round within 10 seconds, point the rifle in a safe direction and wait 15 minutes. In this way, you won’t be injured by a possible ammunition with a hot chamber. Clear rifle.
Use only authorized ammunition that is manufactured to U.S. specifications. Please read this manual carefully before attempting to use your AR-15.

When the round reaches the approximate end of the barrel, expanding gases from burning propellant pass out through gas port and into gas tube. Gas goes into bolt carrier assembly, ejects old cartridge, and chambers a new round.

Operation Under Unusual Conditions
NOTE
Unusual conditions are defined as any climatic condition requiring special maintenance of the weapon.
Perform the maintenance outlined for the climate that most applies to your operational area.
HOT, DRY CLIMATES
NOTE
Hot, dry climates are usually dusty and sandy areas. They are hot during daylight hours and cool during the night hours.
A. Dust and sand will get into the rifle and will cause malfunctions and excessive wear on component working surfaces through abrasive action during the firing operations.
B. Corrosion is less likely to form on metal parts in a dry climate; therefore, lubri­cate internal working surfaces only with a small of cleaner, lubricant and pre­servative (always shake CLP prior to use). Do not lubricate external parts of the rifle. Doing so will only collect dust and sand, making the rifle difficult to keep clean. Do not lubricate internal components of the magazines.
C. Using additional equipment tive bags and overall rifle protective cover will help keep dust and sand from getting into the rifle. Use these items as the situation warrants. As a minimum effort to keep dust and sand out of your rifle, keep the ejection port cover closed, a cartridge magazine installed in the rifle, and a muzzle cap on the muzzle.
Before firing, remove the protective cap and keep for later
use. However, it is not dangerous to fire the rifle with the
protective cap. The cap will blow off when the first round
is fired and may be lost.

NOTE
HEAVY RAIN
Perform maintenance according to the appropriate climatic condition. Use addi­tional equipment rifle protective cover as the situation warrants. Always keep the rifle dry. Using the protective cap will help keep water out of the barrel. Always drain any water from the barrel before firing. Dry the bore with a swab and cleaning rod, if neces­sary.
