disgruntled zealot help needed (mag pumper)

[RamboPreacher]

I am building my mag pumper and have just about everything for it (I have a couple comming soon). My question is: will the X-valve work with it, or does it only work with a certin kind of seer mechanism/measurements.

the x valve would work for it(with lvl 7 bolt parts), but i think the lvl 10 might work with it.

the pump mag works by forcing bolt stick, i think that this would limit you to using something in the strength of the stock bolt spring, because anything stronger would push the bolt back over the sear, and force the gun into semi auto mode.
