Thanks again! Now we're getting somewhere. The offset risers would probably get me where I want to go. The link to the pics shows them well. They look pretty neat & well integrated. Allan's work is always top-notch. I had checked Allan's website & the ring info implied that the dovetail was 11mm, but didn't say that right out. However, Allan replied to an e-mail quickly with that info. I didn't see anything at all about the risers on the website, but they may be something new that hasn't been updated yet. I will contact Allan again.
