A new video from Hyperdouraku which is a follow up of his unboxing and review of the Tokyo Marui M4A1 Gas Blowback Rifle with the ZET System. See it in action as he takes it to the field and we wonder what dummy suppressor he used on the GBB. He also does a full take down of the MWS, showing the ZET System that was designed to make the rifle more durable and perform better.

He then compares test firing, range, and accuracy of the GBB against the M4 GBBs from Western Arms, Tanio Koba, and KSC. Watch the video to find out how it fares to the older M4 GBBs.
