Again, I appreciate the suggestion (I have a Marlin 60 myself) but he's a Lefty. Both of those guns would kick brass in his face.
The link below is the model he has, notice that the brass is ejected down.

What I'm trying to find is a Weaver/Pic base that will will mount to the existing tapped holes allowing him to mount a modern "red dot"...
...and Yes, I'm thinking about this as a Father's Day present for him (the base at least). So SHhhhhhh
...hopefully he wont find this therad.
I am left handed, and shoot left handed. Even with the AR/M16 platforms I've never been hit in the face with brass. Unless he is really crawling that stock it shouldn't be a problem.
