I had a 4 x 32 silver Simmons scope on hand for a future Henry H001-T project so I borrowed it for the Uberti.

Everything in this picture is loosely fitted before final adjustments. The mount is just laying on the receiver, not screwed in yet because there are some other pictures I have to take, minus the scope, before finalizing the scope mounting.
The scope rings are silver colored Millet and were the only choice I could come up with at Gander Mountain or Academy.
I have a Grovetec Hammer Extension (GTHM-284) on hand for my future Henry but it won't fit the thicker Uberti Hammer. Looking at their website, I don't see a Hammer Extension listed for the Uberti. There is probably another one that will fit but I don't have access to any to try out.
Since this rifle will be used most of the time in the 25 to 50 yard range I can't see buying the most expensive scope and rings. Once I find a suitable hammer extension and the proper eye relief distance I may be able to choose a lower set of mounts.
