Hi guy new to the forum and new to airguns.
I have a QB78 that I just got and I want to mount front and rear peep sights like those on a ar2078/tf79 but I have been told that I need to change my breech to a flat breech do to the curve on a stock QB78 is to hi.
Does anyone know a way around this or a peep sight that will bolt on to a stock QB78.
