I don't have one, but others have em and like em a lot, hopefully Digger and Lik2hunt will offer advice on ring height, which will depend mostly on the power ring/ocular bell position above the hammer, I have several 50mm scopes mounted on Handis, medium rings will usually work, but that depends. You can always take a little of the tip of the hammer with a dremel to make just a little room if ya need it, just be aware that it may discourage any free warranty work.
