Hi Outlaw,
It may depend on wheather you have an Uberti or a Chaparral. I have a Chaparral and the Lyman No.2 for the 1886 Winchester fits. My original M'1886 and my Chaparral M'1876 have the same hole spacing. Not sure what the spacing is on the Uberti rifles. Windage adjustment with this sight, if needed, is a simple matter of shimming one side of the base or the other. This is a one time, permanent fix and does not have to be repeated. I am quite happy with this sight on both my M'1876 & M'1886 rifles.
