A couple things I'd like to mention.
I got the EV adjustable rings with the pic mount on the top. I found these way too tall, even for my AR, and I have high cheeks.
Also a bolt in the adjustable height part of the rings snapped off when I went to set to a different height. Hard to explain but these are near impossible to drill out because they are a very hard and brittle steel. Too brittle for this application IMHO. I'm also not in the habit of over tightening things so????!!!! Other than this I haven't had a bolt break off like this in many years.
