Well guys, I bought the flat bolt. I wound up giving $400 for it. 77's aren't my niche, but it has a 22" barrel, sights and what I believe to be the original rings. I assume this makes it a 77RS. SN is 70-14727. I will post picks later. Not sure what I will do with it yet. The stock needs refinishing. There is some bluing wear. I would guess it is around 90% condition. Maybe I will bring it with me "as is" to Boise in January. I will have some Ruger experts evaluate it for me. 8)
