Whilst there is a new MP5 NGRS in the market, Mach Sakai goes over an older, but still a recent MP5 NGRS, the Tokyo Marui MP5SD6 NGRS. This uses the "M-SYSTEM", a feature that employs the electronic trigger method. It uses a microcomputer to monitor and control the FET, FC, battery, and motor comprehensively. This system enhances trigger response and supports the authentic lipo battery set to be released in the future. It provides semi, 3 burst, and full auto modes, meticulously pursuing realism in both exterior design and operability.
