woah nelly!!! i need help

[fuzzynutzipper]

alright... so I gassed up my mag yesterday after oiling it and just cleaning it off... well aparently it wants to shoot fast.... really fast. i have an rt pro... ult... the works. the trigger is going way reactive basically to the point where i have no control over it. i've been sitting here taking shims out of my ult and so far nothing has changed... if anything it has gotten more reactive. could there be any other causes for this? the bumper... i think thats what its called... the clear rubbery piece that sits between the bolt and valve... looks like its seen better days. could this be it??...

i'm gonna keep taking shims out of the ult and see if that does anything... otherwise i'm stumped. i've had it for quite a while and put a decent amount of paint through it and it just now starts doing this...

When you put the ULT in, did you remove all the orings in the valve? And did it have 2 orings in it to begin with?

i got it straight from agd with everything installed. i believe i had... 4 shims in there. with the lvl 10 tuned.

i've pulled out all but one shim. with this, it doesn't go so reactive, but after i pull the trigger it takes a second to recharge. I put another shim back in... and its going reactive like crazy again. its at the point where i can control it to a point... but i don't want to be playing on friday and try to sqeeze off one shot and have a string of 6 going at someone.

What input are you putting into the reg? Back it down a little.

[fuzzynutzipper]

its a preset crossfire ... so 850 psi. can't back it down

[guysdaman]

It may be the regulator on your prset tank is pushing out more than 850 psi. Try it with a different tank if you can.
