I put together a bunch of avialability of bases (1 & 2 piece, flat or sloped, weaver or multi slotted picatinny styled) for rimfire rifle manufacturers. Many of the base makers will provide custom bases for your application, or blanks (undrilled) that you can get drilled and tapped for your rifle, per your specification.

A few of the searches led me to a few interesting dovetail to weaver / picatinny conversion bases and other interesting similiar items, located at the bottom of the post.

Most of these bases can be found at distributors such as Midway, Brownell's, Optics Planet, etc. or straight from the manufacturer.

Please to add to the thread as more are found.

A bunch of other "dovetail to weaver conversion bases" out there, it's best to do a Google search as many enter into the airgun realm.
