History of the M4 (AR15) Assault Rifle

The M4 is a compact automatic rifle of the AR15 platform developed in the United States based on the popular M16 assault rifle. It was designed to meet the need for a lighter and shorter version of the M16, suitable for use in confined spaces and urban combat.
In the 1960s, the M16, developed by Armalite, was adopted by the U.S. Army. The M16 later became the basic design for the M4. In the 1980s, the first M4 prototypes appeared, featuring a shorter barrel and a telescoping stock, improving maneuverability in confined spaces.
In the 1990s, the M4 was officially adopted by the U.S. armed forces as the standard carbine, replacing older models such as the M3 and M9.
The M4 is characterized by its capability to fire both single shots and bursts, making it a versatile weapon.
The M4 quickly became popular among soldiers due to its low weight, compactness, and reliability. It was widely used in conflicts like the Iraq and Afghanistan wars and became an iconic weapon of modern U.S. armed forces.
Besides the standard model, there are many M4 variants equipped with various accessories and upgrades to meet the specific needs of military units.
