Need mount for Tikka Tac A1

[Sogan]

My father has a tikka tac a1. Instead of replacing the base and going rings I want to just get him a different scope mount from his current vertical ring ADM mount (he has the extended that we tried to use but it won’t work). Not sure if 20moa is needed or not but I’d prefer to stay with it. I know badger makes one but appears their only 30mm unimount is extended. What mount should I go with? I’d like to stick around roughly the same price as ADM if possible so $150-200ish
