Do leuppy MK4 rings have any identifing marks? I have a set that are supposedly Leuppy extra high for a flattop AR. they wont tighten up on the rail. They dont fit any of my Pictanny rails.
I tried 5 or 6 times with both rings. Never could get it to tighten. Even tried it on a Warne base that was off the gun, still no good. Are these covered by Leupold?
I figured they are fake, but they are a good copy. Since they have no marks to identify, how can I prove anything? I guess just send them to Leuppy and see what they say.
