Marui M4 System

New Tokyo Marui M4A1 AEG
Based on the M4A1, Tokyo Marui's M4 S-system version shows off some new and attractive features for die-hard airsoft fans!
Features include:
1. Flip up front sight
2. Low profile flip-up rear sight
3. Enhanced butt stock (extend the length of rifle from 768mm to 850mm)
4. Aluminium one-plece barrel
5. Metal skeletal frame for added rigidity and weight
6. Six position LE tactical extendable stock


The S-System has long upper rail, side rails and bottom rail that can accept both airsoft and real accessories. Rails are metal made while the system frame is plastic. The method how the S-System is locked to the gun is simple and well functional. Given the functionality of S-System battery exchange is relatively easy. Unlike in the M4 RIS this time the battery can be stored inside S-System and special wiring is provided with the gun to faciliate this. As in real SIR-system the S-System has holes across its body to allow re-positioning of rail units.
Both flip up sights are fully adjustable and the rear sight is secured to low profile position with help of side lever. Similarly front flip up sight has release button to allow positioning to low profile position
