De-volumizing an X valve

[pbjunky99]

I thought he was running this set up with the on/off closed. With that sais no air can get to the bolt untill he cycles the marker so the pressure shouldn't be an issue as long as the on/off dosnt fail and cause the marker to run a way. Or am I mistaken?

edit: Or is there a pressure point where the on/off will fail and he has to make sure not to reach that point?

Yes but I am hoping this de-volumizing will work with a regular Mag as well.

I can max out the valve without pushing past the on off. so that is not an issue.

That's pretty much what i meant. However my design won't work for the standard mag, only the reversed one that he has as it will as ando said, make the pressure need to be too high to get a decent shot, but the regulator piston will vent well before it reaches that pressure. My design should make for a very efficient reversed mag though, and if you apply a similar idea (smoother transitions) to the normal dump chamber of a normal mag you may see marginal improvements in efficiency, but i don't think it would make a ton of difference.
