Is there such a thing as a pressure compensating cocker lpr that can handle co2? I have a stock class Ion thats using a palmers rock and it works ok, but the first couple shots and the last two are either way low, or way too hot. Was wondering if there is such a thing.

Somebody with more technical knowledge will probably chime in, but I think the AKA SCM is pressure compensating. If you keep liquid CO2 out of it and you’re not shooting a crazy high ROF then I’d think it would work.
At least what’s the harm in giving it a shot? -
Yea, that was the only one I could think of too. I guess I could try one out and see what happens. I probably just have to try to keep the gun more upright when im crawling around to make sure co2 don't get to the reg.Originally posted by Blackmagic71 View PostComment

Explain the pressure compensating to me
Just a guess but too much pressure downstream gets vented?

No matter what the input pressure is, the output of the regulator should not fluctuate until the input pressure falls below it's targeted setting.Originally posted by Trbo323 View PostComment

Within basically rounding error, that's the way all regulators work though. Well, everything in paintball anyway. Input pressure is irrelevant until it drops below the output pressure.Originally posted by Ramfaux View Post
Here's the two most common designs
Moving base
And floating poppet
More lprs are designed as floating poppet over moving base but you can see how the upstream side in both has to decrease in order for the regulator to allow more air in. You can increase/decrease the input pressure and it won't do anything

I'm sure output pressure is normalized to a certain degree, but when you need a very low consistent pressure, even like 10ish psi is enough to cause velocity fluctuations. From my understanding, certain pressure regulators are less sensitive to input pressure swings. I'm assuming it has something to do with piston surface area on each side? I'm not entirely sure what makes up a pressure compensating system but I do know that aka claims the scm is one.

Are you running the LPR straight off the CO2 source or is there an inline regulator after the bottle and before the LPR?

Yea, I'm trying squeeze every last shot out of a 12g so Im trying to minimize any space between the asa and regulator. I even took up the space in the asa above the bucket changer, that was good for 2 more usable shots. Was thinking of putting wire or something in the 90 degree connector before the reg to get at least one more shot. As it is currently I can get maybe 21-22 shots.Originally posted by Grendel View PostComment

21-22 shots on a pump Ion is great. You can drop the input pressure a bit to increase the shot count (aim for 250-260FPS) and maybe sneak a few more out.
At the end of the day you're running a spoolie with a fixed dump chamber. The easiest way to get better efficiency is to reduce chamber size but that means higher operating pressure and hoses popping off.Comment

That was my next thought as well, decrease the dump chamber size
