SA M4 URX Heavy Ops (SA-E06-H EDGE™) - Black/Tan

Assault Rifle M4

M4 is a compact automatic rifle developed in the United States based on the popular M16 assault rifle. It was designed with the need for a lighter and shorter version of the M16 that would be suitable for use in close quarters and urban combat.
In the 1960s, the M16, developed by Armalite and adopted by the US military, was the foundational design for the M4. In the 1980s, the first prototypes of the M4 appeared, featuring a shorter barrel and telescoping stock, enhancing maneuverability in confined spaces.
In the 1990s, the M4 was officially adopted by the US armed forces as the standard carbine, replacing older models like the M3 and M9. The rifle features both semi-automatic and burst fire modes, making it a versatile weapon.
The M4 quickly became popular among soldiers due to its lightweight, compactness, and reliability. It was widely used in conflicts such as the Iraq and Afghanistan wars and has become an iconic weapon of the modern US armed forces.
Besides the standard model, there are many variants of the M4 equipped with different accessories and upgrades to meet specific military needs.
The airsoft AEG assault rifle M4 in the popular EDGE™ series from Specna Arms emphasizes top-notch body craftsmanship.
