I'd find something to put in the chamber. I mill a delrin sleeve to fit. You can't fill the whole chamber , due to the blow forward design , chamber pressure drops off quickly as the PT shaft extends. There's one other key that has to be address to take it further. It's really not a DIYer beyond that point. Your going to have to add and chrono and such till you find a good compromise w/ acceptable FPS.

That's kinda the efficiency nut needed to crack with the mag valve design to start with. Now . . . say for instance you had a 2 peice bolt design the changed that relationship between the . . . Uh . . .never mind.


(Drastically scrambles to get the lid back on the can before any worms get out. )

I will completely ignore the second part of the post till i get as far as I can modifying the reg and finding just the right amount of area to plug up in the chamber...
I've got way more info that i even wanted at this point anyways ... ill dewlve into other things that can be done after i get stuck!!

Luckily the PB store is < a mile from the house and i don't have to go far to use a crono/tools to make that happen.

Fireblade ... don't think your are in the clear yet ... i haven't forgotten about the can of worms you almost spilled ... you will be questioned about it at a later date ...

but in the mean time ... where can one purchase a small amount of delrin for the "devolumization" procedure.

Anyone got a long reg nut and other misc reg parts in the bottom of their box o' junk they could donate... or ill pay if you insist ...
