I have the 34mm version and its typical German engineering and quality. I have adjusted it in the field and can do so very easily and other end users I know also adjust in the field without issues. I dont like adding too much initial cant on the mount for a 100M zero as it produces a lot of compression on the erector spring especially if the weapon is stored for long periods and the reticle at the edge of the glass far from the sweet spot at closer distance shots.
This is just how I do it and YMMV. I advise you have a notebook so you know where you are when adjusting the inclination.
