GENERAL SAFETY WARNINGS DESCRIPTION - Continued

WARNING

EXPLOSION

Do not keep live ammunition near work area.

If the weapon fails function tests, perform required maintenance. Continued use of weapon could result in

injury to, or death of, personnel.

All M16A2, M16A3, M16A4 rifles and M4/M4A1 carbines must be inspected and gaged at least once

annually for safety and serviceability. Initial gaging is required 1 year from receipt of the weapons. Air

Force users refer to inspection requirements in the Air Force Instruction (AFI) 36-2226.

All Army Reserve and Army National Guard M16A2 rifles and M4 carbines must be inspected and gaged at

least once every 2 years, after the initial inspection/gaging procedures have been accomplished. This initial

gaging procedure is required 1 year from receipt of the weapons. This 2 year interval may be maintained

unless preventive maintenance checks and services (PMCS) or other physical evidence indicates that an

individual unit's M16A2 rifles and M4 carbines require inspection/gaging at a more frequent interval. If it

is determined that a yearly inspection is necessary for an individual unit, only that unit will be affected.

This will not affect the interval of inspection for other units.

It is recommended that training units inspect/gage all rifles and carbines at the end of each training cycle.

Training units will inspect/gage all rifles and carbines at least once annually.

Unless performed by qualified maintenance personnel, DO NOT interchange bolt assemblies from one

rifle/carbine to another. Doing so may result in injury to, or death of, personnel.

Bolt cam pin must be installed or rifle/carbine will blow up while firing the first round. If the bolt cam pin is

not installed, injury to or death of personnel may result.

The lock plate prevents the selector lever from being placed in BURST and will be installed at the discretion

of the unit commander. It is mandatory for use in civil disturbance (riot control).

Only blank cartridge M200 is to be used when the blank firing attachment (BFA) is attached to the carbine

rifle. Ensure that the blank firing attachment (BFA) is removed before using live ammo. Use of live ammo

with the BFA attached will result in a blown weapon and personal injuries.

Do not fire blank ammunition at a target at distances of less than 20 feet (6.10 m). The unburned propellant

grains can cause injury within this distance.

For further information on safety, care, and handling of ammunition, Army users will refer to TM 9-1005-

319-10. Air Force users should refer to AFI 21-201, Management and Maintenance of Non-Nuclear

Munitions, and AFMAN 91-201, Explosives Safety Standards.

Any screw longer than 1 1/8 inch used with enhanced rifle grip part number 93949127 could make the

disconnector inoperable, and the weapon will not be able to fire in the burst mode. The loss of burst

capability in a tactical situation could put the operator at risk. Ensure that the washer is in place.
