Hey guys, my mag setup sucks I know, but I went to the field and played with it and....
I could not chrono above 240fps. I'm not sure what the problem was, but I just purchased a new 8" non ported barrel because my 14" J&J custom aluminum barrel has 10" of non porting and only 4" of very small porting. So the gas efficiency is not there.
I also twisted the back like a mofo and got to the point where is pssst at me, and still 250. It wasn't even that cold, but I have a small gas thru 4 grip, that I'm making smaller, and my PE 48CU 3000 psi tank, well, I have no idea the output pressure and have no will to look it up.
I will be purchasing a parts kit, and possibly a power-tube spacer kit before the next time I play. Let me know what parts if anything I should get. My bolt sucks so I'm getting the ANS Venturi 8.hole w/small foamie in middle. I hope to gain some minor accuracy with that as well.
As always, any and all help will be greatly appreciated, thanks again!
