No complaints. To me, scope rings are a think that should be taken for granted. Install them once and never worry about them again. These rings are just that. They have a lot of screws to be tightened, but this ensures that they can be tightened evenly. These rings are NOT light weight, so if you're trying to build a light rifle, look elsewhere. They are solid steel, and being high mount, there is a little more steel than usual.
It would be nice if Burris would make a less expensive, but still just as solid set of scope rings for this application. I don't understand why scope rings are so expensive. It must be the low volume due to all the variety they have to make.
In the end, I'm very happy with these rings on my 77/22 in .22LR.
Pros: Very solid
Cons: Lots of screws
