SA M4 Keymod Light Ops (RRA SA-E07 EDGE™) - 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 to meet 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, 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, which improved maneuverability in confined spaces.
In the 1990s, the M4 was officially adopted into the arsenal of the US armed forces as the standard carbine, replacing older models like the M3 and M9. The rifle is known for its ability to fire both single shots and bursts, making it a versatile weapon.
The M4 quickly became a favorite 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 modern US armed forces.
In addition to 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 popular EDGE™ series by Specna Arms emphasizes top-notch body craftsmanship with licensed markings from the firearm manufacturer Rock River Arms.

Internal Parts

The M4 Keymod Light Ops (RRA SA-E07 EDGE™) replica is equipped with a MOSFET X-ASR module from the Polish company GATE. This module ensures safe switching and protects internal parts, improves trigger response, and extends battery life. It also increases the gun's rate of fire and allows for safe use of Li-Pol batteries 7.4V and 11.1V. Thanks to integrated status LEDs, the module can even diagnose basic malfunctions in the gun.
From the start, the M4 is equipped with a precise 6.03 mm barrel that enhances accuracy and an adjustable Hop-up chamber with a high-quality rubber.
Additionally, the increasingly common standard today, the ESA Quick Spring Change system, allows you to install a stronger or weaker spring as you see fit. The spring can be changed without having to remove the gearbox from the gun's body; everything is easily done through the stock tube.

The gun also features a brand-new type of Light Ops stock with a rubberized cheek rest and QD sling swivel sockets, which is light and minimalist.
