The VFC Colt MK18 Mod1 Gas Blowback Rifle is available in Japan, and configured to meet the local laws. This is fully licensed from Colt and also uses a fully licensed Daniel Defense rail system, SOPMOD Stock. In a review by Hyperdouraku, he finds the build close to the real thing, especially the texture but does he find it as a good performer in airsoft games, where it really matters?
WGC Shop posted a video of the new Vega Force Company MK18 Mod1 Gas Blowback 2015 version. This uses the VFC M4 GBB V2 System and uses the Daniel Defense RIS II and with Colt Markings. This is expected to be released this month and WGC Shop will be one the stockists of this GBB.
A short review of the VFC MK18 Mod1 Gas Blowback Rifle by Eddie of CRW-Airsoft. This is a fully licensed from Colt and you can see the official markings on the receiver. It has an initial muzzle velocity of 400-420fps using 0.2 BBs and Top Gas. As for the price, prepare to shell out US$500.00 and this comes with its own unique serial number.

Must be the effect of playing BF4 all night). We're reserving time for the game this weekend...
