Ching I just want to share the trouble i am going through now. The GP tube i bought in in KWS last week is perfect fit! Dont even need the tube nut!
However i have no yet found a good combo for the hopup yet. Can use G&P magazine though.

China Hop-up = no good. Hop up rubber has deformed due to impact

F22 Ching, I think you are very skillful! I tried to find a 9.5mm drill bit but seems no where sell that size! only 9mm and 10mm drill bits... Anyway i bought the Prime hopup, maybe save the china hopup for some other experiment subjects. Now it works wonderfully.

But i still encountered some other problem in the bolt carrier. I know it need some grinding at the back, but it seems the energy bolt does not perfectly match the BC so need to enlarge the guide hole in the guide plate a little. Dont know if you have encountered such problem.

Also i found the C-clip sticks out a little from the BC, and it is quite loose and can move back and forth. I was thinking to add a small copper plate to better protect this fragile 'thing'. If ching have any advise very appreciate!
