I bought one several years ago to use on my first mauser build. I needed a varmint type scope and didn´t have much to spend at the time. It is a decent scope for what it is.
Other than zeroing it, I have not adjusted it very much so I can´t comment on repeatability. Optical clarity was decent. Absent mirage conditions, the entire magnification range is usable. The AO works well, just don´t pay attention to the distance markings. The outside diameter of the objective is HUGE, so the scope has to be mounted pretty high. This is a big, heavy scope.
Because of its size, weight, and how high I had to mount it, I ultimately replaced it with a BSA tactical scope from Midway. The BSA won´t impress anyone at the range when I uncase my rifle (for that matter, neither will my rifle) but I really like it.
