M16 / M4Immediate ActionSPORTS

Slap the magazine to ensure it is fully seated

Pull the charging handle fully to the rear

Observe for the ejection of a round or shell

Release the charging handle; do not ride it

Tap the forward assist

Squeeze the trigger and attempt to fire

Description

The trigger is pulled, and although the hammer falls on the round, the bullet is not fired from the chamber.

Page 7: Malfunctions & Corrective Actions

M16 / M4Failure to FireCauses

The most common cause of a failure to fire is an improper loading sequence.

The second most common reason is failure of the bolt to go completely into battery, which is often caused by bad

ammunition or a dirty rifle.

The common, non-mechanical reason is a bad primer.

SPORTS

To remedy a failure to fire, execute SPORTS.

While clearing this malfunction, keep the muzzle up to allow gravity to aid clearing and to keep your vision oriented towards

the threat or threat area.

M16 / M4Failure to Feed

Description

Failure-to-FeedA round is not picked up by the bolt and/or chambered.

Double FeedTwo rounds are picked up by the bolt and attempted to be chambered

Bolt Override (double feed) The shock of firing dislodges a round from the magazine and if the shooter is at an odd angle, it can become jammed into the gas tube

Page 10: Malfunctions & Corrective Actions

M16 / M4Failure to FeedCauses

Failure to feed malfunctions are almost entirely caused by an unserviceable magazine.

Although unlikely, another reason for failure to chamber a round is dirt or grime on the round casing.

SPORTS

This is remedied using SPORTS.

If done properly, the malfunction will be cleared before the word “malfunction” gets out of the shooter’s mouth.

Description

Failure to UnlockBrass is stuck in the chamber and is holding the bolt closed

Stove-pipe (failure to eject)An expended case is sticking out of the ejection port at a 90˚angle

Page 14: Malfunctions & Corrective Actions

M16 / M4Failure to EjectCauses

The most common cause of a failure unlock is ammunition that is slightly of shape round casing.

The common cause of a stove-pipe is shooting too close to an object, where the ejected casing would bounce back into the

ejection port.

EBACK

As the shooter begins SPORTS, he should see the empty casing sticking out of the ejection port and immediately cease the “Pull” portion of SPORTS.

With the other hand, remove the casing while the bolt is partially back, before the bolt can pick up another round from the magazine
