If you get a good picatinny rail to mount your scope on you could use just about any flip up rear sight for the AR platform.

I am sure with how popular the 10/22 is there is someone out there making one, but I could be wrong.


EDIT: Actually now that I think about it. When I cleaned out my gun tool box today I think I had a 1913 type scope rail for a 10/22. If it is something you are interested in let me know I will dig it out and get you some pictures.
