We probably have lost track of the custom 10/22s made by the Airsoft Surgeon, but most probably this is the 4th custom work on the KJ Works KCO2 which probably is one the fun airsoft guns to customise. This we assume to be Green Gas or Top Gas compatible and with 6.03 Prometheus Inner Barrel. As to the designation of this custom 10/22, we'll know more about this when it gets is product page at the RedWolf Airsoft online store.
