PMR Misfiring/not releasing air.

[swifty123]

Hi,
Ive got a pmr with a ul frame that i bought a week or so ago and cant get it to fire properly.
When im gassed up I have no leaks, and when i fire, the bolt moves up and down as if its dry firing but im not getting enough air coming out and i end up having paintballs rolling out the end of my barrel.

It makes a phut phut sound when i pull the trigger.
Ive tried increasing the dwell,replacing the o-rings and the gasket under the solinoid and changed the battery....ive also tried another reg off another pmr.


Ive noticed other people have had this problem but they never said how they solved it!

Any ideas?

Thanks
Charlie.

Probs the dwell setting on the UL board, ts not the same as the stock settings on the pmr board. I cant remember the exact ins and outs and ya best downloading the manual for the UL (nearly sure its 18 or 28). You did say you tried changing the dwell but did you go as high as the manual says?

Sorted a dudes gun out not so long ago and that was his problem to

Yeh ive gone from 18 and increased it by 2 at a time all the way up to 30 and still no difference, the bolt isnt sticking though, thats what is confusing me!

Try changing the velocity? stick an alan key up and keep turning until it sounds better and balls come out as per usual. If possible take it down to your local site and stick over a chrony. How much air you trying it with as anything under 800psi and i wont fire properly.
