Prior to taking it apart to clean it, I could not get it to shoot over 200fps, and it was very inconsistent. That is probably a spring problem though. I built this gun from accumulated parts.
Next time I am near a chrono I will put the reg on another gun and see what it does, and put a known good reg on the gun in question and see what i come up with.
For now, I just want to know the proper way to service this thing, and what I should be looking for to get it working right.
Thanks for the responses so far guys
