Maybe I'm using the wrong search phrases, but I can't find much info about this. Need to get higher rings after mounting my new MDT ESS folding chassis, so figured I might aswell get a one piece mount with built in 20 moa cant as I would probably get a new rail anyway down the line. I know about the Spuhr mount, but what other options are there for 30 mm tubes, either solid 20 moa or adjustable?
