What should the diameter of the arbor be on an Uberti/Cimarron 1860 R&M conversion be? Also the ID of the arbor hole in the barrel assy.?
I have one that I recently purchased that the barrel is a bear to get off and on. Thinking if I could find the id I could use a properly sized reammer to chase the hole out and if not that is not the problem, then work the arbor down to the correct diameter.
Thanks
