WARNING
ALL WARNINGS in this technical manual pertain to both the rifle and the carbines unless otherwise specified.
Before starting an inspection, be sure to clear the rifle. Do not pull the trigger until the rifle 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.
To avoid injury to your eyes, use care when removing and installing spring-loaded parts.
All M1 6A2 rifles and M4 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 Air Force Manual (AFM) 36-2227, Volume 1.
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 other units in regard to the interval of inspection.
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.
Below direct support maintenance, 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.
Dry cleaning solvent is flammable and toxic and should be used in a well ventilated area. The use of rubber gloves is necessary to protect the skin when washing rifle parts.
When using solid film lubricant or dichloromethane, be sure the area is well ventilated.
When using carbon removing compound (item 8, app D), avoid skin contact. If carbon removing compound comes In contact with the skin, wash thoroughly with running water. using a good lanolin base cream after exposure to the compound is helpful. Using gloves and protective equipment is required.
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 is attached to the rifle/carbine.

WARNING Before starting an inspection, be sure to clear the weapon. Do not pull 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. NOTE An inactive weapon is a weapon which has been stored in an arms room for a period of 90 days without use. The weapon may or may not have been assigned to an individual. Inactive weapons shall receive quarterly PMCS unless inspection reveals more frequent servicing is necessary. Normal cleaning (PMCS) of an inactive weapon will be performed every 90 days. Should the unit armorer detect corrosion on a weapon prior to the end of the 90-day period, the PMCS should be performed immediately. Solid Film Lubricant (SFL) is the authorized touch up for the M16A2 Rifle and M4/M4A1 Carbine and may be used on up to one third of the exterior finish of the weapon. FOR ARMY CONUS USE ONLY AND AIR FORCE TRAINING WEAPONS ONLY: Solid Film Lubricant may be used as a touch up without limitation on the upper receiver and barrel assembly. This is to say that units which DO NOT fall under the category of Divisional Combat Units or rapid deployment type units may have up to 100 percent of the exterior surface of the upper receiver and barrel assembly protected with SFL.. Prior to application of SFL, the surface must be thoroughly cleaned and inspected for corrosion and/or damage. If corroded or damaged, the part must be repaired or replaced prior to application of SFL. Continued use under combat conditions would result in an unprotected surface when the SFL wears off. This would result in a large light reflecting surface and accelerated deterioration of the unprotected surface. Therefore, Divisional Combat Units and units which fall under the definition of Rapid Deployment type must adhere to the limitation of NOT over one third of their exterior surface covered by SFL. When determining mission capability, deadline if it is a deficiency. 2-4 Change 4 |

RIFLE: | |
General Barrel and barrel extension | Clear rifle of any ammunition and Inspect In accordance with paragraph 3-25. Check barrel erosion. Use barrel erosion gage 8448496 for chrome lined barrels. Stripping of lands and grooves shall not be cause for rejection unless so determined by barrel erosion gage. Visually inspect, using chamber reflector tool 8448201. Pits 1/8 inch (0.31 cm) In length and those pits large enough to extend from the body of the chamber into the shoulder stop area and forcing cone area are cause for rejection. Large pits are defined as those 1/8 inch (0.31 cm) or more in diameter as determined by visual Inspection. Only closed flash suppressors are acceptable. |
Check barrel for straightness using bore straightness gage 8448202. Gage must pass freely through the bore to be acceptable, either dropped from the muzzle or chamber end. | |
Front sight and gas tube | Inspect gas tube for proper alignment with carrier key. Gas tube must not bind when mating with the key. Evidence of gas leaks around the front sight connection of the gas tube shall be cause for rejection until rifle has been function fired to determine if the loss of gas is sufficient to cause malfunction. |
If function firing malfunctions occur, repairs are neces | |
sary. Inspect front sight for damage. |
Item | Standard | |
---|---|---|
Bolt carrier group | Inspect bolt for elongated or oversized firing pin hole using plain | |
cylinder gage 12620101. | ||
Firing pinholes which permit the plain cylinder plug gage to fully | ||
penetrate at any position on the circumference will be rejected. | ||
Bolt face with a cluster of pits which are touching or tightly grouped, | ||
covering an area measuring approximately 1/8 inch (0.31 cm) | ||
across will be rejected. | ||
Bolts which contain pits extending into the firing pinhole will not be | ||
rejected unless firing pin hole gaging check determines | ||
rejection. | ||
Bolts which contain individual pits or scattered pits will not be | ||
cause for rejection. | ||
Only phosphated bolt carriers are acceptable. Both phosphated and | ||
chrome plated bolts are acceptable. | ||
Bolt locking lugs and bolt | ||
cam pin hole | Inspect for cracks in the locking lugs and cam pin hole area. Use | |
a black light, if available; otherwise, use a glass of no more than | ||
3X magnification or use inspection penetrant (item 25, app D). | ||
Use instructions contained in kit for application. If cracks are | ||
detected, the bolts will be replaced. | ||
NOTE | ||
Particular attention must be given to the area where | ||
the lugs meet the bolt body and around the side walls | ||
of the cam pin hole. | ||
Bolt rings must not be broken. Ring gaps must be properly spaced | ||
approximately 1/3 turn apart and not in line. | ||
Firing pin protrusion must be not less than 0.028 inch (0.071 cm) | ||
or more than 0.036 inch (0.091 cm). (Use firing pin protru | ||
sion gage 7799735.) | ||
Socket head capscrews must be staked. | ||
Carrier key must not be dented where end mates with gas tube. | ||
Repair or replace damaged carrier keys. | ||
Headspace | Inspect headspace using headspace gage 7799734. Excessive | |
headspace will be cause for rejection. | ||
Trigger pull | Inspect trigger pull using trigger measuring fixture 7274758. | |
Trigger pull must be minimum 5.5 pounds (2.49 kg), maxi | ||
mum for M16A2 and M4 is 9.5 pounds (4.31 kg) and | ||
maximum for M4A1 is 8.5 pounds (3.86 kg). Test trigger | ||
