I originally bought the PEPR for my 223. I changed it out to a LaRue because of the QD mounting system. i now have 2 scopes (hunting and 1x6 3 gun scope) that a switch between on 1 rifle. The guy that built my creed uses the AD mounts, so that's what I went with.
My PEPR now sits on the shelf with no scope in it. I never had any problems with it though. Now that I have 4 ARs, I might find a use for it.
I don't have any other suggestions. Sorry
If you shoot a young deer because a neighbor will shoot it, you are that neighbor.
