Anyone know if there is output valves, fill valves, o-rings, that I can get here in the states that'll work to rebuild a mag? I've done the "contact us" link twice on the kjw website with no reply. Also anyone ever have luck with ra tech hop up rubber. I installed one (I have tdc mod) and it just made the bbs jam as soon as I adjusted hop up. I went back to stock hop up rubber.
