The Colt M203 Grenade Launcher is a lightweight, single-shot, breech-loaded 40mm weapon specifically designed to be attached to the M4 Carbine and the M16A2 and A4 Rifles. 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 ammunitions. A complete self-cocking firing mechanism, including barrel latch, trigger and positive safety lever is included in the receiver, which allows the M203 to be operated as a completely independent weapon even though attached to the Colt M4 Carbine or the Colt M16A4 Rifle. The M203 provides Colt M4 Carbines and Colt M16A2/A4 Rifles with breaching, defilade, and area engagement capabilities, making it an essential tool for every modern army.
