Generally a "Medium" will give absolute co-witness and a "High" will give 1/3rd. So, .... 21mm / .83 should be just about right, with 25.5mm / 1" for a High.

I have NO idea what small, medium or large means in Bushnell talk. The OP might do better on TOS. I doubt very many over here have any experience with that sight. Remember that the sight he is talking about has a built in clamp. A pic to pic riser is what he is forced to use.

I have two of these sights. I am out of town at work and just can't remember which mount I have. Just needing to order another one.
