The top level has been around a long time (Mounting Solutions for $30)and the problem you just can't get around is there is no way to see it without breaking cheek weld to see it. Scoplevel brand has a tall mount that overcomes the issue with a 3" tall mount but it is kind of fragile. With a low profile top mounted level you get it level and lose zero. Adjust zero and lose level till you go crazy trying to get both aligned just right.
The Holland Signature Series level is the highest quality one that actually works. With a little practice I can see it and the reticle at the same time. There are other side levels like Vortex for a lot less money but they are clunky and crude.
