I have a M94 Win no safety, straight eject. I need a Williams rear sight. I have looked in Buffalo Arms and Midway. It isn't clear to me which one to order. I don't want to get the wrong one. Any help will be much appreciated. Thanks,

You should be able to sort out which one you need.

Perfect GTS, I found what I want for the M94 and I Thank You. At that site is listed sights for dovetail grooved receivers. I need one. One is for a high line of sight and the other one is for a low line. How do I measure to determine which one I have? It is a Ithaca M72 Saddle gun .22 Mag that shoots great. Any help will be appreciated.

Try looking at the info near the bottom of this page:

I think you should be able to work out which height of front sight you will need.

I just read your post again. I think I misunderstood what you were asking, but the link above may be of some help.

Thanks again GTS. I can figure it out from here.
