level 10 problem

[iisp0tii]

i just got my level 10 today & it works, its just that it wont shoot over 200 fps. if i turn it up it leakes out the back, and i have the smallest spring that came in the kit on the bolt. i also only have one shim in it if that helps anything.

Put in another shim and try out the medium spring. Hope that helps.

You probably need a new regulator piston. The built in saftey is venting too early. BTW, this really belongs in the Tech forum. :D

I'm with HiTech on this one. Mine did the same as yours before I got a new piston. The new reg pistons are blocked off so they don't vent at all; you can turn your velocity nut all the way in and it still won't vent.
