Posting a light weight alloy Badger Unimount model 306-96. The website says "extra high". It came on a new (2 month old) NXS 50mm scope I purchased here this past week. The rings are not lapped and there is no lock tite on the screws. The 50mm front sits 1/2" above barrel. I like it lower so went with NF Ultralight rings instead. $175 shipped to conus.
