from the Colt Military website:

'Colt is the main small arms supplier of the U.S. Military (exclusive production through 2009 of the M4 5.56mm Carbine). All branches of the U.S. Military use Colt weapon systems, including the M4 Carbine and the M16A2/A4 Rifle. Colt weapon systems are also used in fifteen (15) NATO countries and more than 80 other countries worldwide. More than 8,000,000 units have been produced so far of which more than 90% remain in service. This represents more than 90% of all weapons produced in 5.56mm.'

Of the above M4 and M16, I'm sure Colt have an very close eye on upgrading this little grenade pumper with something from the MST inventory:

quote: 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.


I mean, single shot... what the!?!?


good luck
