This is the lowest mount currently for the AK. For rings get a cheap set at http://www.freedomoptics.com. You can also get the same mount there, but goodoptics is much cheaper. Personally, I'd be careful what rings you get. The cheap stuff is usually just that, cheap. Almost any quality ring will work with this mount.
Leupold, Zeiss are just a few good rings. Go to http://www.swfa.com for wide variety of rings.
Thanks for the advice MacMan
