Replacement for Mdl 94 sights wanted.

[Blktail]

I have a model 94 30/30 with the buckhorn rear sight. I can't stand the danged thing. I have a lot of trouble aiming consistently with that type of sight.
My '92 44-40 has a standard type of rear sight which also flips up. I can shoot that thing fast and accurate out to 200 yards.

Question is: can I get an alternate sight for the '94 that is CAS legal? I would like either standard iron sights, an adjustable peep or tang sight or a flip up like the '92.

Thanks,
