I just got a minimag for an awesome deal, and its basicly stock except for the fancy oldschool smartparts splash anno parts, anyway, I was woundering what the stock minimag valve can handel if I say want to make it a pnumamag...I was woundering if I will have massive shootdown after like 5 BPS like I hear about, or if it is good for a bit till I get the money for an Xvalve...or if I should not expect it to be as fast as most mags that I have seen...and they are blazin!
