I see. I just brought a china gun. A Well R6. I tried to modify it and I've been addicted. I fixed all possible air leaks by applying some teflon tape. Changed the barrel to a 510mm 6.03ID tightbarrel, changed the cylinder to type 0, changed the plastic bushings to metal bushings, re-shimmed then installed a SP120 spring. Tested on a poor man's chrono using .2 BB, it made a hole at bottom central then dimpled on the other side (top).
I'm planning to change gears and the piston body soon so that I can install a SP130. Now my china gun shoots just like my CA M15A4 Carbine. The only thing I didn't like about the china gun is poor quality plastic material, no real gun logo and the barrel is not one piece.
Anyway, I want to buy the china M14. I've seen it and it really looks like the marui. it also has metal parts. I'll modify it also once I've brought it.
