I agree with Cayugad, those see through rings make it moredifficult to shoot accurately with iron sights and take away the advantages of speed and visability that you normally have with irons and your head is floating so you can not shoot as accurately with the scope.
A really good pair of quick disconnect scope mounts [ don't trust the cheap ones] gives a better answer for shooting either and has the added advantage of getting it out of the way when cleaning. Lee
