Hello Bryan, I have the same mount, the adjustment of the AR worm is quite simple, the only thing that is contrary to the sample video, I do the adjustment in several steps, first I separate the worm from the crown and I adjust it a little to the crown, then I tighten the worm block and this movement will bring the worm a little closer to the crown, I adjust the distance from the worm to the crown again definitively and I give a strong tightening to the worm block and that would be it, It's very easy to do, good luck.
