My Reg has this huge gap between the Reg and the Frame
This happens when you crank on the reg without air being in the marker. Don't treat your reg like a throttle and it won't happen again!
Now for the fix: unscrew your reg, and put the silver top in a padded vice (or stick an allen key in the hex-hole on top) unscrew the top bonnet by at least 1/2 a turn. (if you used the allen key method, try to turn the small screw back 1 full turn, otherwise your reg might over pressurize) Put the reg back on your marker and turn until the logo lines up where you want it to. If it REALLY bugs you, take the silver piece all the way off and put a SMALL drop of BLUE threadlock on and it won't budge again.
