Rifle Scopes Mk4 ring cross bar measurement?

Re: Mk4 ring cross bar measurement?

I took a set out and mic'd them. They were actually .14'', recoil lug width. I also heard that Leupold changed the Mark 4 rings a few years ago so they would fit on most Weaver rails. Interesting find, I thought they were tru picatinny spec.
