SA M4 URX (SA-C06 CORE™) - Black

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 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 a 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 is characterized by its ability to fire both semi-automatic and automatic, making it a versatile weapon.
The M4 quickly became popular among soldiers due to its light weight, compactness, and reliability. It was widely used in conflicts such as the Iraq and Afghanistan wars and has become an iconic weapon of modern US armed forces.
Besides the standard model, there are many variants of the M4 equipped with various accessories and enhancements to meet the specific needs of military units.
The airsoft AEG assault rifle M4 in the basic CORE™ series by Specna Arms emphasizes lightweight nylon body but also top-notch craftsmanship and fit. The body is reinforced with fiberglass and is more durable than common zinc alloy in cheap metal bodies, which will be appreciated by both beginners and advanced players who prefer fast action in the style of speedsoft, where every gram is just extra weight. This type of body is also found on weapons like the CZ Scorpion Evo or MP7.
