Knight Rolling Block KRB7

[GLB]

I have had this muzzle loader setting around for years. i want to put it back in action. Looking for a peep sight like a Williams that would mount to the scope base holes.
since this is an older rifle I’m not sure what would fit. Recommendactions?

I get to answer my on question . I mounted the Williams FP Legend sight and it went right on no problem.

Always liked the looks of those rifles. Sight looks like it should work out great
