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 create 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, formed the basis for the M4. In the 1980s, the first prototypes of the M4 emerged with a shorter barrel and a telescoping 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 both semi-automatic and fully automatic firing modes, making it a versatile weapon. The M4 quickly became popular among soldiers for its lightweight, compactness, and reliability. It has been widely used in conflicts such as the Iraq and Afghanistan wars, becoming an iconic weapon of modern US armed forces. In addition to the standard model, there are many variants of the M4, equipped with different accessories and enhancements to meet the specific needs of military units. The airsoft AEG assault rifle M4 in the upgraded EDGE 2.0™ series by Specna Arms emphasizes top-notch body craftsmanship with licensed markings from the firearm manufacturer – Rock River Arms.

What does the Specna Arms M4A1 (RRA SA-E03 EDGE 2.0™) offer?

Internal Parts

The M4A1 RIS replica (RRA SA-E03 EDGE 2.0™) is equipped with a processor unit ASTER by the Polish company GATE. This unit ensures safe switching, protecting the internal parts, improving trigger response, extending battery life, and increasing the rate of fire. It allows for the safe use of Li-Pol batteries 7.4V and 11.1V, and can adjust trigger sensitivity, pre-cocking, and various firing modes. With integrated status LEDs, the unit can diagnose basic weapon malfunctions. The M4 comes with a precise 6.03 mm barrel, which increases accuracy, and an adjustable Hop-up chamber with a high-quality rubber. The increasingly common QSC ESA2 quick spring change system allows you to install a stronger or weaker spring as desired. Spring replacement requires no special tools – you just need to loosen the tube nut to access the QSC screw of the gearbox. The reinforced gearbox contains high-end internal parts (listed below), and is capable of handling springs up to M120 (as indicated by the manufacturer Specna Arms in their description of the ORION gearboxes).
