SA M4 CQB M-LOK (RRA SA-E25 EDGE™) - Black

M4 Assault Rifle

M4 is a compact automatic rifle developed in the United States based on the popular M16 assault rifle. It was designed to be a lighter and shorter version of the M16, suitable for use in close quarters and urban combat.
In the 1960s, the M16, developed by Armalite and adopted by the U.S. military, served as the foundational design for the M4. The first prototypes of the M4 appeared in the 1980s, featuring a shorter barrel and a telescopic stock, enhancing 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 like the M3 and M9. The rifle 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 such as the Iraq and Afghanistan wars and became an iconic weapon of modern U.S. armed forces.
Besides the standard model, there are many variants of the M4 equipped with different accessories and enhancements to meet the specific needs of military units.
The airsoft AEG M4 assault rifle in the popular EDGE™ series by Specna Arms emphasizes top-notch body craftsmanship with licensed markings from the firearm manufacturer Rock River Arms.
