GHK Airsoft announced that they have released the first 200 units of the GHK M4 Gas Blowback Rifles to answert the first 200 domestic pre-orders (which means Taiwan orders). There have been delays due to ensuring that the material used will be able to withstand the vibration caused by the hard-kick recoil of the GBB-R. The first owners are lucky as the package comes with a free limited edition Tri-Lug QD Flash Hider.
