Airsoft Lefty shows the customised Tokyo Marui M4A1 MWS Gas Blowback Rifle made to look like the BCM MCMR. It is an 11-inch MWS GBB which he finds to be sick. If you want an MCMR airsoft version, but don't have the time to customised a Marui M4A1 MWS, there is always the complete MCMR made for BCM Air by VFC.
