Prime Mech Airsoft showcases another quick demonstration of their custom MP5 SD6 silenced build, featuring the Cyma MP5 SD6 (CM.041). This custom airsoft SMG is equipped with ASTER II Bluetooth technology, a 22 TPA motor, a 13:1 SSG with 13 teeth, and delivers 1.3J at 0.30g. Built in their workshop in France, they say that this is designed to provide the fastest and cleanest trigger response while maintaining the quietest AEG performance.
