Takeo Ishii reports for Hyperdouraku as he goes inside the KSC office in Japan. In the video he made, he shows the KSC M4A1 AEG which has the electric recoil and blowback that you will assume to be using the same technology as another brand. In the video he also tests the KSC Makarov Blowback Pistol which indeed gives a strong blowback function.
