Combat prototype
The Colt M4 automatic rifle was developed in the USA on the basis of the M16A2 rifle and was originally intended for arming combat crews and fighting equipment personnel, for whom the excessive length of the M16A2 was a hindrance.
The carbine has a shortened barrel and a collapsible buttstock, making it even more compact. Despite a slight decrease in the shooting characteristics, the great convenience of using the compact carbine led to the fact that it was adopted as a must have weapon for all U.S. special operations forces, and now it is used by the U.S. Army.
