dancoman;
I just purchased a Sightron 3X12X42AO to put on top of my Bushmaster Varmiter in 223. This is the second Sightron I've bought, my other is a 2.5X8X42. And it's been on several rifles. Never had any kind of trouble out of the scope. That's why I bought another one. Could not see spending about $250.00 more for a Leupold, and I've got several.
I think that they are one of the best scopes made for the money.
Sorry, I can't help you on your specfic scope.
Dennis
