Drop a PM to F3Z or Andy Piper, they'll point you in the right direction
Otherwise, i've been told that if you loose all the pressure out of the tank, you can actually strip the reg and remove the shims to lower the pressure but it depends how low you need to get it?
cheers for that mate
there is only one shim in the reg,i know the lp kit replaces the 10 spring stack with a 12 spring stack that is softer,dont know if taking out some of the harder spring stack will drop the output tho?
Technically it shouldnt matter what type of sys you use as its your reg which does the actual regulating into the gun, although angels and some others are funny.
it does work ok the only thing is i can only get it down to 275fps and it just goes over the 280 mark every so often which isnt good if thats the time its being chronod at a tourny
