I've had excellent luck with Burris products (Scopes, mounts and rings) over the past 20 years. I wanted quick detach rings for my muzzleloader, enough to justify buying Burris again. Will they return to zero everytime? I don't know enough to guarantee it yet, but I expect to update this with positive results soon.
I've read great reviews from Doc White and Randy Wakeman on the Warne QD mounts and rings. The Burris rings are a BIG savings over Warne rings.
Pros: Solid, well made, good looking rings
Cons: None I've found yet
