Well, i had a few questions about the LPR

From what i understand, screwing it in lowers the force (in PSI) that the bolt is pushed back with, all the way in is 25 PSI, one 180 degree turn is raising it 5 PSI (from starting position), factory default was 75 psi (5 full turns from being all the way in)

Now my marker seems to have a crapload of kick, so i was wondering, what do you guys think i would be able to set it at? I hear that some people set their PM5 to 1 1/4 turns, i dont get how, thats like, 40 PSI of force, isn't that too low?

Any help is appreciated, right now im going to reset it to the factory default (all the way in then 5 turns out)

Nobody can really answer this. So many other factors. Temperature, dwell, variances in markers,etc. Last time I totally rebuild a PM5 I set the lpr to factory and tweak everything else.

Okay thanks, ill just have to mess with it when it's aired up and make it low, but also so that the gun still cycles, its at 60 psi right now

You got the idea. Just have to play around with it.

Lower it as far as you can without making the marker inconsistent. Then raise the pressure about a quarter to a half turn for good measure. That's generally how I set up my PM8's LPR and it shoots great.

How to Tune your DM/PM

Or

"2 Ways To Reduce Kick:

1. The higher the dwell, the lower you can turn the LPR down; so the bolt moves a little slower for a little longer. This is how the Ironmen tune their guns (Dwell:19-21 LPR:2-3; Basically they set their dwell then lower their LPR til it drops-off then raise it about a 1/4 of a turn)

2. You can decrease the HPR pressure, this will in turn lower the psi in the dump chamber which will result in less kick

Both of these methods will make the marker quieter and softer on paint at the expense of not being as efficient."

Speedball has nothing to do with how fast you shoot and everything to do with how fast you move. - Crawdaddy (PBF)
