seems no big difference between the original and precision inner barrel in terms of "J".......
but i wonder how various of barrel length affects the "J"? did c hing do any experiment related to it??? ...

Sorry, I can't. I don't wanna disassemble the HOPUP and change to another barrel(s) again.

可能PTW原裝管已經好好。
