Things I liked:the flip up covers, the ease of adj., the see through mount with one screw, makes this a breeze to mount or remove from your rifle and still retains accuracy. Things I would have changed:Would like to have a 3moa mil dot instead of a 5moa. / at 100 yards you will cover a 6 inch target. Don't get me wrong, You will hit what you point at. What others should know:I shot the 1.5 inch center out of a 6 inch Shoot N C target at 25yds using 22 cal bullets, it took 25 rounds, for a 5moa mil dot that's not bad.
