The American assault rifle M4 rifle: photos and specifications of weapons

M4 Rifle – it is a unique weapon created by American engineers. The basis for the future famous rifle was the M16A2, which was lit in many world conflicts. From the outset, it was calculated as the primary weapon for vehicle crews and mechanized units.

The Experience gained since Vietnam, showed that the army needed a new rifle to replace the M16A2 and will be more effective in different combat conditions. The new weapon was supposed to have all the performance characteristics of its predecessor.

History M4: its predecessors

U.S. Commanders made the decision to develop a new series of reduced variants of the famous M16. For this case came from the firm "Colt", then and now known for its revolvers. In the mid-1960s, it intensified its activities, and on the basis of the AR-15 and M16 were made and implemented in production "Colt Commando", which had significantly shortened the barrel and for the greater convenience of telescopic buttstock. It was also replaced by the forearm and Dulova brake-compensator, which stabilized the shooting. Rifle "Commando" in many ways is not inferior to the "big sister", but won for practicality and mobility. In the course of development has also produced other rifles, immediately entered service some parts of the USA and the UK.

Revival rifles

The Vietnam War ended, and interest in new developments immediately lost. Only in the early 1990-ies was remembered about these carbines. Trying to get rid of outdated guns "Beretta M9", submachine guns М3А1 and MP5, the U.S. command decided to re-equip some parts of the new carbine ready to replace the old weapons.
