I put a Buehler on a rifle and thankfully there were no additional mods that were needed so no worry there.
I was also lucky that the pick up cam didn't need to be polished or adjusted for smooth operation but that may not always be the case.
Theirs also a long weaver quick detach mount for longer scopes that will almost but not quite allow the safety to work.
In my case you could rotate the safety just enough for it to work but it was not quite satisfactory enough for me to not find a Buehler.
I paired it with a Weaver K4-E which turned out to be a good combination overall.
