I got this scope AK, and the other 2 when, I 1st joined ODT, was going to change out the scope but when, I took it to the range it was hitting the bullseye at a 100 yards every time. So, didn't mess with it.
I use bifocals , but my daughter who's in the glasses business sent me 5 pair of glasses just with my distance prescription, I went to Bulls-Eye range last week and hit a bulls eyes or head shot with a shot dead center. This worked for me, by the way I suck with a Red-Dot, was never taught how...
I had to get bi-focals. Then my daughter sent me 5 pair of designer glasses and I now have to use bi-focals for reading,_ and my regular glasses for driving and long range shooting. Getting old sucks
