The new Tokyo Marui MK18 Mod.1 Gas Blowback Rifle is now out in the market and we're getting more and more reviews about it. In this case we have the top-notch Japanese airsoft blog Hyperdouraku, check it out when it first came out last month. Just like the previous AR-style GBB-Rs released by Tokyo Marui, the M18 Mod.1 also uses the ZET system making it one of the most, if not the most, reliable gas blowback rifles in the airsoft market.
