I just upped my reg to 140b. It’s not a horrible job but also not super simple. The reg has no marks like a Huma so it involves some guesswork. The simple version without writing a novel here is you have to get the reg out of the tube first. I found that the extra screws that come with UTG scope mounts fit into the bottom of the reg. So I tack welded the screw to a piece of all thread and used it to pull the reg from the tube. Once you have the reg out, put a flat blade screwdriver in the brass slot in the bottom of the reg. Do not let it turn when making the adjustment. I used a 2mm hex wrench to turn the little wheel with the holes in it. Taipan says turning the wheel 180 degrees is 10b. You can only spin that wheel a little at a time through the slot provided so you wonder how will I know when I spun it 180. Well it takes 12 turns to spin it 360 so I went 6. That’s clockwise with the intake facing up. I got +10b. The key is using the flat blade to not let the brass spool spin while making the adjustment. If you just spin the tiny wheel with the holes in it, the whole spool spins and it doesn’t change anything. Good luck.
