Newer model 1885

Hello All,
I am a new poster here and have a question on a newer Winchester 1185 Low Wall, 22LR, made in japan. I would like to mount a scope on the rifle. there are 2 holes in the reciever and I am just guessing but it looks like maybe the rear sight may use another set of mounting holes. Am I right on this assumption or cannot I mount a scope. If possible, any recomendations on mounts, ring heiht, etc. Thanks.
