I have a Savage 99 that is not drilled and tapped for a scope mount and has a cocking indicator. There are two holes drilled and tapped behind the cocking indicator.

What I am looking for is a receiver/ peep sight such as a Williams Foolproof or Lyman. I would rather not settle for a flip up "tang" style sight.

Are there any sights like I want in current production?

If not, were they once made and what should I look for?

Thank you if you can help me.
