Glad I could help. I believe they say in the instructions to back the screw out one full turn (at least that is what I remember). That is "VERY CRITICAL" with the micro adjust on these sights. If you saw the inside of the sight and saw how the mechanics work you would understand. There is a cam lever that pivots and makes contact with the threaded lead screw. If you don't back out far enough, then the cam lever doesn't make contact with the lead screw properly and will have problems with the micro adjust. On the same note, if you back the set screw out too far then the cam lever gets pulled away from the lead screw and doesn't adjust either. So not enough of a turn and too many turns out is bad on these. I've found that 1 full turn to 1.5 turns usually works well. Again, easy to understand once you see the inner workings. I have seen and had problems myself where they don't work. I think in my case I ended up needing new cam levers from Axcel. My suggestion here if you are doing it correctly and yours still doesn't adjust properly, then just order a whole new pin from Axcel. It will come complete with all the parts you need and fix your problem. If anyone needs help with these sights, just send me a PM and I can send you an email that I quickly put together that has some instructions and pictures of how to work on them.
On another note, as some others mentioned, you don't want to tighten the pins too tight either which can also cause problems. Snug works just fine.
