I run Badger steel rings and have had ZERO problems with them. I bought some NF rings 5 years ago and had some movemnet which blew my mind bc my rifle had moderate recoil IMO. I'm not harping on NF so don't get your panties in a bunch just telling you my experience with their rings. I run their scopes on all my rifles but not their rings. I also was given a new set of Seekins rings and I REALLY like the design of them. Thoughts? What rings do you run?
