I've had a 4-16x40 CenterPoint from Wal-Mart for well over 2 years and it has been mounted on at least 5 different centerfire rifles, from 257R to 30-06. It has withstood quite a few rounds downrange with my target shooting.
However, it is not a scope that stays on a rifle very long. I have no gripes with its adjustments, tracking and etc., but of all my low end scopes, it probably has the poorest optics for clarity, brightness and etc.
