Differences between KSC and KWA:
The only difference is the box, both KSC and KWA are in fact the same, they are made in the same factory in Taiwan to exactly the same specifications. This is contrary to what some people believe in that KSC guns are made in Japan. However it is confusing as KSC have made it so that only KSC and not KWA guns are exported to Japan. Whereas KWA can be exported to every other country, in general a KSC gun is more expensive partly due to the cost of first shipping the gun to Japan.
