Mostly my fault because I didn't realize that they come with a 30moa scope mount on them. I've tried several scopes and can't get close to on paper because of that slope. They really don't need 30 moa for a rimfire. Called them and they are willing to sell me a new rail that they don't know when it will be available. Looking online and EGW makes one but something is f'd with their site and I can't order. Can I get a set of 20 moa rings and just mount them backwards to counter the stupid slope?
