Hi Richie:
I have a SA 6-20X56mm Mil-Dot Scope. I do not know if there are any similarities, however, this scope has super bright optics and the sight picture is outstanding!
I do not have any "real" negative comments about this scope... the only thing I might forewarn people about is that the objective bell is huge!
Is it worth the money? IMHO, it is! But if you are going to purchase retail, you might want to look at the VX-III Leupold scopes that are about the same price.... maybe with M1 or M3 turrets... its just a thought.
This is what mine looks like next to a M8 6X Leupold Scope...
Aloha and Best Wishes,
Tom O.
