Having reviewed the KSC HK33 AEG, Mach Sakai tests the AEG for accuracy at distances of 10, 20, 30, and 40 metres. This AEG is not new and was released almost 15 years ago. Based on the G3 rifle, this KSC version deviates from the Marui as it does not use a stick battery. If battery goes dead, you can disengage the gearbox and shift to manual cocking with the front cocking lever allowing you to still fire even without battery power.
