Talk lever guns to me.

Henry big boy X model are threaded and railed, and come in 357/38. But hard to find.

Maybe their website sucks, I was looking at it and looked like only the big boy 4570 or whatever they call it was fully featured.
Edit. Ya looking at the page looks like that has an accessory rail not a optic rail.

Granted I could modify a gun but its nice to be off the shelf.
