Re: Burris Signature Series Scope Rings
I used mine on a 30 Cal with no brake for thousands of rounds and had no movement whatsoever. I've had the scope off at least 30 times now in the last year and they go back in place as nice as anything I've seen. Still, the only scratches on my scope are the ones I get from working on the gun, banging it around.
If you have something that you disassemble and reassemble enough times, sooner or later, you'll have two!
