New here and looking for advise

[Longcarbine]

Howdy all! New guy here from Missouri and looking for a little advice. I am about to purchase a Uberti 1885 High Wall Sporter model with a 32" barrel in .45-70 and intend to put on a globe front sight and either a Lyman style peep sight or a vernier style sight on the rear. Which would you recommend for this rifle. I also have a Browning 1885 High Wall which I would also like to add such a rear sight to but the Brownings do not have a metal tang on which to mount one, is it feasible to drill and mount it to the wood stock at the wrist. Any advice is much appreciated.
