KC-02 CQB w/rail slots

This is a CQB body kit for the KJW KC-02 airsoft gun. Add an M4 AEG stock of your choice (and an M5 nut to hold its bolt in place), an M4 GBB grip (re-use the square nut from the original KC stock), an M5 bolt up front to hold the receiver in the body and some rails if you want, and you're ready to go.
