Rt Pro problems

[marshallf221]

My RT Pro valve won't go under 342 fps, anyone have any suggestions that I can try?

check your reg seat and the o-rings in the reg pin.

They are all new, best I can figure out is something is hanging up, it was all the way up at 490 fps when I got it.

Velocity related issues are in the reg section. Check the reg seat and reg pin orings.

Gonna treat it down tomorrow, thanks.

that's wild, it doesn't leak out of the side or back? i'd unscrew the reg body, take the regulator adjust nut off and push the regulator piston out (easy to do with a small allen wrench or something). replace the piston o-ring if needed, and clean the piston and inside of the regulator body. oil the piston o-ring and reinstall.
