SA M4 CQB (RRA SA-E04 EDGE™) - Chaos Grey

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, suitable for use in confined spaces and urban combat.
In the 1960s, the M16, developed by the company Armalite and adopted by the US military, was the basic design for the M4. In the 1980s, the first M4 prototypes emerged with a shorter barrel and telescopic stock, improving 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 the ability to fire both semi-automatic and fully automatic, 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 the modern US armed forces.
In addition to the standard model, there are many variants of the M4 equipped with various accessories and upgrades to meet the specific needs of military units.
The airsoft AEG assault rifle M4 CQB in the popular upgrade EDGE™ series from Specna Arms emphasizes premium body craftsmanship with licensed markings from the firearm manufacturer Rock River Arms.
