Interesting, didn’t know warns was making horizontal split rings now. I like their vertically split maximas, but I’ve never had a set mount true enough to install per the instructions(I always have to leave the bottom screws loose to be able to adjust/rotate the scope before tightening everything up).
I’ve had good luck with the Burris zee rings, I especially like the quick detach rings for my guns with irons. A little cleaner looking and lighter than the warnes.
