Here's hoping that some of you may have started on the double rifle journey as I need to, with a less expensive over and under.

I just got a very nice Valmet 412 30-06 and would like to avoid adding 40% to the guns cost by buying the ridiculously expensive removable scope mount.

Has anyone here had one drilled and tapped for a standard scope base, and if so which base (original application) works?

Thank you,
CHAZ
