SA M733 Commando (RRA SA-E02 EDGE™) - Black

M4 Assault Rifle

The 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 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 (XM177, CAR-15) appeared, featuring shorter barrels and telescopic stocks, improving maneuverability in confined spaces.
One of the shortened M16 variants from the Vietnam era is the Colt 733 (M733), also known as the Commando, intended as a special operations weapon for units like Delta Force, who favored its light and short design.
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 a favorite among soldiers due to its light weight, compactness, and reliability. It was widely used in conflicts such as the Iraq and Afghanistan wars, becoming an iconic weapon of modern US armed forces.
Besides the standard model, many M4 variants are equipped with different accessories and upgrades to meet the specific needs of military units.
The airsoft AEG M4 CQB assault rifle in the popular EDGE™ series from Specna Arms emphasizes top-notch body construction with licensed markings from firearm manufacturer Rock River Arms.
