I have used an ARMS #35 for many long time on my AR's.
I use the high #35 rings. It holds my 3 inch spacing.
The mount always repeats zero. I uses this scope on 3 ARs.
I used this mount in Sandland with no problems.
I kept my Leupold scope in a plastic bag in my backpack.
I have a couple of the American Defense and really like them. Just put my daylight scope back on one of my Grendel uppers after it having been off for 2 months, and it was within 1 click at 200 yards. To me that is about as repeatable as it gets.
