What is your opinion of the Burris Extreme rings? I have converted several rifles over to them, and, the rifles don't seem to be as accurate as they were. I have not switched rings on them to see if the Burris rings could be the problem.
They are light, and look strong and seem to lock down on the rail like they should.
A few years ago I bought a rifle with a picatinny rail and decided on Burris Extreme Tactical rings. I have been so impressed with them I now have them on several rifles. I think they are great but some do not like them. I like the six screws per ring and they seem to stay locked on the bases also. Nightforce and other companies make better rings but the XTR's are a great value for the money. I have had no complaints with the XTR rings or bases.
IIRC it isn't in the instructions for some kooky reason, I installed my first pair backwards as well, the cross bolt of your XTR rings is milled with a flat on one side & is round on the other. Nut goes on the left side, slot facing forward to interface correctly with your picatinny rail. Hope this helps.
