LMAO! No, seriously, the cross bar has (or used to) have a flat milled on one side & not ther other. I assumed (I know, I know) that was for a larger purchase against the lug of you picatinny rail... I would have to agree it does look tougher on the bolt side, ah... the benefit if being a south paw!
No, don't do that just yet, i've got a couple sets as home in my parts kit, i'll verify when I get there (about an hour or so). Hang til then, i'd feel like a real tool for havin you strip you scope off to find out I was full of crap.
If it makes you feel better, one of my rifles is still sporting them backwards (thats when I found out). I wonder if the other "big" rings sport that type of cross bar? Like the Maxx 50's & such....
Well sir outlaw... you were correct so I put it back together correctlyand fortunatley the alignment bars indicated no additional ring lapping was required so it was a quick fix. I loaded another 5 .075 off the lands this time so hopefully I get her at least under an inch this time!
