I have a SS10X42M mounted with Armalites 1 piece mount, on a AR10T. For the price it can't be beat. Decent glass, holds zero with accurate repeatability. The elevation turret on mine is a little mushy feeling and the audible is weak also. Is a Luepold , Nikon, Zeiss etc. better? Yes but at what price? The side parallex adjustment is worth the cost IMHO, it's just easier to use.
