I'm a newbie to this forum with a question about scope ring height. I recently purchased the Design Competition 10/22 and I want to mount a Leupold VX-1 Rimfire 2-7x28 scope. I had to return the gun to Ruger for an iron sight issue, but while it's away I wanted to order rings for the scope. Can anyone tell me what height rings I need to clear the aperture rear sight? I was going to use the Burris Signature rings, but I'm open to suggestions regarding the best rings for this application. Any help would be appreciated.
