I don't know where you guys got you're info on the PSA adjustable gas block but their is some misinformation in here.
The front screw, parallel with the barrel, is the set screw. The side screw, perpendicular to the barrel, is your gas adjustment screw.
Back off the front screw first, adjust the side screw, then tighten the front set screw.
