Tang for H&R buffalo ???

[JasonYuke]

Does anyone know or has anyone put or re-fitted a rear tang sight for a H&R Buffalo Classic, this gun really needs one, the williams peep are ok but just ok.
Any suggestions or point in the right direction would be helpful, BTW ya ya ya! I know should have done it right and bought a sharps.

Williams also makes tang sights. Don't know if they do for an H&R though.

Not everybody has the wherewithall for a Sharps. The last one I saw was well over a grand. Sometimes ya just gotta make do with what you have.
