My new Smart Parts "EOS" is awsome but I dont know how to change the velocity...

I think its the black nut on the bottom but not sure. If so do I change it with allen keys, or what do I need to do in order to up and down the velocity/pressure?

[vicioussrevenge]

its your reg or aka "front grip". That is what you use to chance your velocity.

Download the full manual off of SP site. shows you exactly what you need to do including all allen wrench sizes for doing it

allen wrench size 4 inside the bottom of the regulator not the black nut twards the trigger turns it up away down
