These were the recommended rings for my Winchester/TOZ Wildcat rifle. The gun rails are a little picky on std. ring mounts and these were a perfect fit. It has a special star type torx screws, you don't want to lose that little wrench...
Pros: High quality
Cons: doesn't use std hex, its star torx screws
