Maydaysan Airsoft purchases what he calls to be the Japan's most popular gas blowback rifle, the Tokyo Marui MWS CQB-R Block 1 GBB and he shares his experience... "The Tokyo Marui CQBR BLOCK 1 is by far Japan's and perhaps the world's most popular airsoft GBBR. Due to its compact size, ready to use setup, and of course the reliable ZET system, this airsoft GBBR is the perfect base to build the airsoft toy of your dreams. If you plan to use the Tokyo Marui CQBR BLOCK 1 overseas, you best upgrade it, but honestly for CQB for engagements less than 20m, you'll be just fine using this CQBR GBBR."
