looking at the thing, it looks to me as when you are trying to zero it, you dont so much move the reticle as you move the entire sight assy by using those outer screws to provide the vertical and horizontal movement and then the allen screws just hold it there, is that somewhat correct, and I must ask,,,,, HOW DO you use the ring sight if you have 2 mags clipped together, i cannot see through the dang thing without just holding it out and not shouldering it at all, I think im going the tro aimpoint rail thingee does it sit high enough to allow the covers to close or will the be permanatley opened???? :grin:
