After releasing their full auto CQB version of the KJ Works KC-02 GBB Rifle, Future Energy show to us their new "Underground Weapon" SOG Version of the same rifle. This has the Future Energy wood kit for KJ Works KC-02 installed, plus the full auto conversion. The woodkit itself costs US$125.00 so we expect a fully completed SOG version to be sold higher than this price.

Also they have a 70º Hop-Up Rubber for KJ Works KC-02 for those who want to replace the original hop-up.
