Years ago my neighbor bought a Mueller APV. I don't recall the magnification. He bought it because of all the hype he was reading at Rimfire Central. I looked at it and thought it was a steaming pile of crap. The eyebox was very tight and unforgiving and I went no further than that because I considered it to be unusable on account of just that alone.
I wouldn't buy one...there are too many scopes out there that are more usable.
