Use standard rings and scope or iron sights, don't try to mix them up to have your cake and eat it too.
I like Millet 1" rimfire tip off rings, medium height will fit the vast majority of scopes anybody might consider putting on a Marlin semi auto.
Because Marlin 60/795 ring grooves can vary quite a bit dimensionally, don't use a ring with a fixed block on one side and a tightener block on the other.
Choose a ring which allows adjustment of both sides of the ring blocks.
Millet rings are designed this way.
I gave up on a scope for my Model 60, to get a decent one mounted to the rifle would cost more than the rifle, goofy in my book.
I instead opted to use an old Lyman Target Foolproof rimfire receiver sight on mine and got lucky.
It clamped down correctly.
Now I have to try a few front sight blades to get it to regulate the way I want it to.
I also installed a Williams shorty ramp on the front and it looks like a narrow .290" or .312" high blade will be the ticket.
The .260" I have on it now is too short.HTH
