เอ็ม203



Colt’s M203 Grenade Launcher is a lightweight, single-shot, breech-loaded 40mm weapon designed especially for attachment to the M4 Carbine and the M16A2/A4 Rifle. It creates a versatile combination weapon system capable of firing both 5.56mm rifle ammunition as well as the complete range of 40mm high explosive and special purpose ammunition.
The most commonly used ammunition for the M203 is the M406 antipersonnel round, which has a lethal radius of five meters, and the M433 multi-purpose round which, in addition to having fragmentation effects, will penetrate up to 3 in. (7.6 cm) of armor plate. Many other types of ammunition are available, such as buckshot, tear gas, and various signal rounds, which greatly increase the versatility of this outstanding weapon.
The receiver of the M203 is made of high strength, forged aluminum alloy, which offers it extreme ruggedness, yet keeps weight to a minimum. A complete self-cocking firing mechanism, including barrel latch, trigger and positive safety lever is included in the receiver, allowing the M203 to be operated as a completely independent weapon, even though attached to the M4 Carbine or the M16A2/A4 Rifle. The barrel, which is also made of a high strength aluminum alloy, slides forward in the receiver to accept a round of ammunition, and slides rearward to automatically lock in the closed position, ready to fire.
The new concepts of rapid deployment, mobility and increased firepower now play a major part in the overall strategy of modern warfare. Providing M16A2/A4 Rifle and M4 Carbine with area firing capabilities, Colt’s M203 Grenade Launcher is an essential tool of every modern army.
