I prefer the Lyman 48, in my estimation, the most sophisticated and precise of those types mentioned above. The Lyman 57 would by my second preference and such as the Redfield Model 70, if I recall Model correctly. Understand that not only the D&T of course required but also the stock to be inlet to accommodate. 'Sometimes the 48, in it's last - 3rd Series can be mounted without the inletting. But "a miss is as good as a mile", if it requires inletting, a "little bit" IS inletting. I'd avoid the black alloy Williams iteration, as my opinion the others mentioned are better!.
My listing for the 48 by type of rifle is only for factory models. I 'suspect' the Model "M" For Mauser, is correct, but you need to be sure whichever model you elect. Someone here or another Forum should have the exact model nomenclature for fitment. There are also the choice on most of these sights of "hunter" or "target knobs". Less often presumed adjusted, utilizing "coin slot" adjustment knobs OR more often, a knurled pattern respectively.
Now, as the saying, if you're not confused... You're not paying attention!
Good luck & Best!
