I have a old RST-4 that is missing the front sight, inquiring through this forum last year I learned that it would be better and cheaper to obtain a replacement barrel and receiver than it would be to have a gunsmith install a new front sight.
I have found a barrel and receiver from a MK II and I would like to know if it will work on my RST-4?
