5.56mm center-fire ammunition is issued in the form of a complete round, A complete round (cartridge) consists of all the components (cartridge case, bullet or shot, propellant powder, and primer) necessary to fire the weapon once.

---

Machine gun ammunition is linked by a disintegrating metallic split-linked belt for firing. The M27 link is a reduced size of the M13 7.62mm link. The body link fits into the extractor groove on the cartridge case. The U.S. Navy uses the link with the M63 Stoner Machine Gun. The U.S. Army uses the link with the M249 Machine Gun.

Cartridge, 5.56mm, Ball, M193

The cartridge is used by the M16 and M16A1 rifles. The cartridge is intended for use against personnel and unarmored targets. This item is a training standard item used in both training and combat.

This cartridge can be fired by the M249 machine gun, but accuracy is degraded; therefore, it should only be used in emergency situations.

The M193 cartridge has a bullet with a copper alloy jacket and a lead antimony alloy core. The cartridge is identified by a plain bullet tip.

Type Classification: STD - AMCTC 5143. Type Classification Date: 1975.
Unit cost: $0.24 (Fiscal Year 2005).

Cartridge, 5.56mm, Grenade, M195

The cartridge is used by the M16 and M16A1 rifles. The cartridge provides pressure, on functioning, to project grenades to a desired target using a grenade projection adapter.

The cartridge is identified by a rose-petal (rosette-crimp) closure of the cartridge case mouth sealed with red lacquer.

Type Classification: STD - AMCTC 6919

Cartridge, 5.56mm, Tracer, M196

The cartridge is used by the M16 and M16A1 rifles. The tracer is intended to permit visible observation of the bullet's in-flight path or trajectory to the point of impact. Its main uses are for observation of fire, incendiary effect, and signaling.

This cartridge can be fired by the M249 machine gun, but accuracy is degraded; therefore, it should only be used in emergency situations.

R284 tracer. The cartridge is identified by a red bullet tip.

Type Classification: STD - AMCTC 5055

Cartridge, 5.56mm, High Presure Test, M197

The cartridge is used by the M16 and M16A1 rifles. The cartridge is used to proof test weapons during manufacture, test, or repair. The cartridge is loaded with a special propellant to produce pressures substantially in excess of the service round.

The cartridge is identified by a stannic-stained (silvered) or nickel-plated cartridge case.

Type Classification: STD - AMCTC 4484

Cartridge, 5.56mm, Dummy, M199

The cartridge is used by the M249 machine gun and M16/A1/A2/A3/A4 and M4-series weapons. The cartridge is used for practice in loading 5.56mm weapons, for simulated firing to detect flinching of personnel when firing, and for inspecting and testing the weapon mechanisms. This round contains no propellant.

The cartridge is identified by six longitudinal corrugations (flutings) in the cartridge case and by the absence of a primer. The primer well is open to prevent damage to the firing pin. d.

Type Classification: STD - AMCTC 4662

Cartridge, 5.56mm, Blank, M200

The cartridge is used by the M249 machine gun and all 5.56mm rifles (M16/A1/A2/A3/A4 and M4-series weapons). A blank-firing attachment must be used to fire this ammunition. The cartridge is designed for simulated firing in training exercises and for saluting purposes. The M200 blank cartridge has no projectile. This is a training unique item; not used in combat.

The original M200 blank cartridge had a white tip. Field use of this cartridge resulted in residue buildup, which caused malfunctions. Only the violet-tipped M200 cartridge should be used.

The cartridge is identified by a rose-petal (rosette-crimp) closure of the cartridge case mouth. An engraved knurl is located 1/2 inch from the head of the cartridge case.

Type Classification: STD - AMCTC 5942. Type Classification Date: Prior to 1977.
Unit cost: $0.09 (Fiscal Year 2005).

Cartridge, 5.56mm, Dummy, M232

The cartridge is used by the M16 and M16A1 rifles. The cartridge is an inert round used for testing the mechanisms of 5.56mm weapons.

The cartridge is identified by a black chemical finish over the entire round and by the absence of a primer.

Type Classification: STD - AMCTC 4485
Unit cost: $0.52 (Fiscal Year 2005).

Cartridge, 5.56mm, Blank, M755

The M755 blank cartridge is especially designed for use with the Sting Ring Airfoil Munition System which consists of the M234 launcher and the 64mm riot control M743 projectile fired from the M1GA1 rifle.

The cartridge is only for use with the M234 riot control 64mm projectile launcher. The launcher is attached to the flash suppressor of the M16A1 rifle and actuated by firing an M755 5.56mm blank cartridge. The M755 blank cartridge is the only cartridge that will give the projectile M743 the proper velocity. Use of other blank cartridges may damage the system.

The blank cartridge is fed into the firing chamber. When fired, the primer ignites the propellant. The expanding propellant, gases pass from the muzzle of the rifle into the launcher manifold. The projectile is ejected from the launcher barrel to a maximum range of 328 feet (100 m). The propellant charge is not sufficient to eject the cartridge case which must be ejected by pulling the charging handle of the rifle all the way back.

The cartridge is closed with a seven petal nose crimp and moisture sealed. The crimped tips of the cartridge is painted with yellow lacquer for identification and thus lessen the chance of mixing them with the standard 5.56mm blank cartridges.

Type Classification: STD - MSR 04786005

Cartridge, 5.56mm, Ball, M855

The cartridge is used by the M249 machine gun and the M16A2/A3/A4 and M4-series weapons. The cartridge is intended for use against personnel and unarmored targets. This is a training standard item used in both training and combat.

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 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 longer projectile of the round).

The cartridge is identified by a green bullet tip.

Type Classification: STD - MSR 05826003. Type Classification Date: 1982.
Unit cost: $0.26 (Fiscal Year 2005).

Cartridge, 5.56mm, Ball, M855, Lead Free

The M855 "lead free" ball cartridge has a bullet with a conical steel insert and a tungsten composite core in a copper alloy jacket. The intended use is to maintain environmentally "clean" ranges.

The cartridge is identified by a green bullet tip.

Type Classification Date: 1982.
Unit cost: $0.38 (Fiscal Year 2005).

Cartridge, 5.56mm, Tracer, M856

The cartridge is used by the M249 machine gun and the M16A2/A3/A4 and M4-series weapons. The tracer is intended to permit visible observation of the bullet's in-flight path or trajectory to the point of impact. This is a training standard item used in both training and combat.

The M856 tracer cartridge has characteristics similar to the M196 tracer with a slightly longer tracer burnout distance. The M856 is ballistically matched to the M855 ball cartridge. The tracer bullet delivers a visible red light signature through its trajectory. The M856 does not have a steel penetrator.

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 projectile of the longer ammunition).

The cartridge is identified by an orange bullet tip.

Type Classification: STD - MSR 05826002. Type Classification Date: 1982.
Unit cost: $0.30 (Fiscal Year 2005).

Cartridge, 5.56mm, Plastic, Practice, M862
Cartridge, 5.56mm, Short-Range Training Ammunition (SRTA), M862

The cartridge is used by all rifles when equipped with the M2 training bolt. The cartridge is for training in local and urban training areas where range restrictions preclude use of full range standard service ammunition.

Although M862 SRTA closely replicates the trajectory and characteristics of service ammunition out to 25 meters, it should not be used to set battle sight zero of weapons to fire service ammunition. The settings that are placed on the sights for SRTA could be different for service ammunition.

If adequate range facilities are not available for sustainment training, SRTA can be used for any firing exercise of 25 meters or less. This includes the 25-meter scaled silhouette, 25-meter alternate qualification course, and quick-fire training. SRTA can also be used for Urban Operations training.

The cartridge is identified by a blue plastic bullet.

Unit cost: $0.61 (Fiscal Year 2005).
