I want to put a folding rear leaf sight on my Savage 99 that has just a blank in it now. It's drilled and tapped for scope mounts/rings and already has a vintage Weaver K3 on top.

I am thinking it would be nice to get a folding rear leaf sight.

Is there a specific Lyman or Marbles model number someone can recommend?

My other 99 has the lyman tang mounted sight, but, it too could use a folding rear sight. My lyman needs some TLC and I'd like to keep it in shooting condition while a gunsmith who specializes in Lyman sights fixes it.

Thoughts?
