Larue 104SPr or 135, which is the same height as the aimpoints. Is there a reason yiou don’t want the Larue? It’s what I used for a couple of years with the NF 1-4 and FC2 reticle. I don’t know anything about the mount you did ask about.
You can’t beat Mark LaRue’s customer service and AD isn’t going to give you a hat, a tactical beverage entry tool, and a jar of dry rub when you buy a mount from them.
I have a soft spot for the underdog too. I looked at the AD mount before I got my LaRue, it is a solid enough piece, I’d buy one of their mounts in the future if I found it met my needs.
I like that the bottom ring half appear to be more fixed, like a unimount, rather than 2 side halves. Seems like a better way to get the scope aligned so it’s not pointing left or right.
