Does not fit the kwa gbb version hence why I'm selling it ,does not include the body pins it is made of plastic and not metal like the kwa version reciever plate. I wish the kwa version had the spring that this one has to dampen the recoil to prevent the infamous body crack that plagues the kwa gbb version Offer up not looking for much just enough to compensate for my time to send it out to you, let me know if you have any questions PayPal only
