1. US RIFLE M16A1 CAL. 5.56 MM St. Mary’s Academy – Honor Guards Unit Poblacion , Dalaguete , Cebu Lecturer: Liston, F.B. (Commandant)

2. I.            CHARACTERISTICS     The US Rifle M16A1 Cal. 5.56 mm is a shoulder weapon that is air-cooled, gas operated and magazine-fed. It is designed for either a semi-automatic or fully-automatic fire through the use of a selector lever. In addition, it has the following characteristics.               a. The rifle is equipped with a flash suppressor that also serves as a stationary piston that permits the launching of rifle grenades without the use of supplementary attachments.             SMA-HGU

3.             b. Its barrel is surrounded by two aluminum-lined fiberglass handguards which serves as a foreman. The handguards are notched to permit air to circulate around the barrel, and further serve as a protector for the gas tube.              c. The hard rubber pad attached to the butt of the stock reduces partially the effects of recoil. SMA-HGU

4.   d. Its forward assembly located on the right rear of the upper receiver allows the closing of the bolt when this is not done by the force of the action spring.              e. It has a “clothespin” bipod used in the prone and foxhole positions. The bipod is attached to the barrel directly beneath the front sight between the bayonet lug and the front sling swivel. SMA-HGU

5.  f. The trigger becomes easily adaptable to winter operations. A spring-loaded retaining pin is depressed with a cartridge point to allow ready access to the trigger with arctic mittens.              g. It is provided with a dust cover to prevent dirt or sand from getting into the rifle. The dust cover should be closed during periods when firing is not anticipated. It opens automatically by the forward or rearward movements of the bolt carrier. SMA-HGU

13. III.    TYPES OF AMMUNITION SMA-HGU

14. Ammunition Types and Characteristics. 1. Cartridge, 5.56-mm, Ball, M193. The M193 cartridge is a center-fire cartridge with a 55-grain, gilded metal-jacketed, lead alloy core bullet. The M193 round is the standard cartridge for field use with the M16A1 rifle and has no identifying marks. SMA-HGU

15. 2. Cartridge, 5.56-mm, Tracer, M196. (Used in the M16A1 rifle) The M196 cartridge has a red or orange painted tip. Its main uses are for observation of fire, incendiary effect, and signaling . Soldiers should avoid long-term use of 100 percent tracer rounds, which could cause deposits of incendiary material, or chemical compounds that could damage the barrel. Therefore, when tracer rounds are fired, they are mixed with ball ammunition in a ratio of no greater than one-to-one with a preferred ratio of three or four ball rounds to one tracer round SMA-HGU

16. 3. Cartridge, 5.56-mm, Dummy, M199. (Used in all rifles.) The M199 dummy cartridge is used during dry firing and other training. This cartridge can be identified by the six grooves along the sides of the case beginning about 1/2 inch from its tip. It contains no propellant or primer. The primer well is open to prevent damage to the firing pin. SMA-HGU

17. 4. Cartridge, 5.56-mm, Blank, M200. (Used in all rifles.) The M200 blank cartridge has no projectile. The case mouth is closed with a seven-petal rosette crimp and shows a violet tip. SMA-HGU

18. 5. Cartridge, 5.56-mm, Ball, M855. (Used in the M16A2/3/4 and M4-series weapons.) The M855 cartridge has a 62-grain, gilded metal-jacketed, lead alloy core bullet with a steel penetrator. The primer and case are waterproof. This round is also linked and used in the M249. It has a green tip. This ammunition should not be used in the M16A1 except under emergency conditions, and only at targets less than 90 meters in distance. (The twist of the M16A1 rifling is not sufficient to stabilize the heavier projectile of the round). SMA-HGU

19. 6. Cartridge, 5.56-mm, Tracer, M856. (Used in the M16A2/3/4 and M4-series weapons.) The M856 tracer cartridge has characteristics similar to the M196 tracer with a slightly longer tracer burnout distance. This cartridge has a 63.7-grain bullet. The M856 does not have a steel penetrator. It has a red tip (orange when linked 4 to 1 for the M249). This ammunition should not be used in the M16A1 except under emergency conditions, and only at targets less than 90 meters in distance. SMA-HGU

20. Cartridge, 5.56-mm Short-Range Training Ammunition (SRTA), M862. (Used in all rifles.) The M862 SRTA is designed exclusively for training. It can be used in lieu of service ammunition on indoor ranges and by units that have a limited range fan that does not allow the firing of service ammunition. SRTA ammunition must be used with the M2 training bolt. SMA-HGU
