I went outside yesterday to test fire my KP and I can't get it to go below about 350 fps. It has a regulator off of a Trilogy since it was the only one I had lying around. Is this the reason I can't get it to chrono any lower? I'm trying to get it ready to sell so any help would be appreciated
The reg might need some relubing. Try that. The reg is supposed to be able to drop pressure down to 0. Velocity screw on reg is clockwise to lower velocity. Screw on back cap is counter clockwise. If lubing doesnt work, looks for a rebuild kit for your reg. or a new reg.
