Got one the other day and am thinking about changing sights from the rear buckhorn & front post to a lyman front globe and some kind of ghost ring or peep rear sight. My eyes are not what they used to be and the buckhorn is hard to be very accurate with for me. I will want to use for hunting some so don't really want a tiny peep that will be hard to see thru at low light conditions. I will be shooting mostly 300 grain factory loads. The rifle has a 30" octagonal barrel. Any suggestions on sights? Will a ghost ring work where the dovetail is for the rear sight or is that too far forward? How do I tell what height front or rear sight to order? Does anyone know the dovetail size uberti uses? Thanks.
