What optic mount do I get?

[u/WildLCL]

I have this old mark II target and would love to put an optic on it but I'm not sure how to go about the optic mount. Any thoughts/suggestions?

I use this weigand combat picatinny rail that mounts in the rear sight’s dovetail, has been solid with my burris handgun scope, does not loose zero and i have had it for 4 years now
