The KWA SR-10 is out of stock at Airsoft GI and they don't know when they are going to have it back in stock again. What they did is to give you something similar to it by having a KWA M4 Commando as a base gun and made two customm KWA Mid-Length M4s for you to choose from: the KWA Full Metal M4 Noveske and the KWA Full Metal M4 Troy.

If you like what you see, better check them out at Airsoft GI's online store.
