There is not a set of Leupold Dual Dovetail DD Rings that would allow for use of iron sights on a Henry rifle. Please email us at techsales@opticsplanet.com for more information.
I would recommend using the DNZ Products Game Reaper Scope Mount or the Leupold RifleMan Savage Axis/LA Scope Mount (linked below)

Would need to be 30mm tube with High ring height.

These rings will fit the dual dovetail bases.
Leupold recommends a high height ring for a scope with a 44mm objective.
I would recommend MPN:51730 for the rings and MPN: 51727 for the bases.
If you are using dual dovetail bases you will likely want to use MPN: 49918 or any of the high height options.
No, these require Leupold Dual Dovetail bases to mount. You would need Leupold's rimfire rings: https://www.opticsplanet.com/leupold-22-rimfire-no-tap-ring-mounts.html?_iv_ring-height=0-dot-98-in
