This is a Featherweight barrel for a Winchester model 70 rifle, chambered in .308 Winchester. This barrel was manufactured in 1953.
Bluing and Metal - 95% - This bluing on this barrel is dark and with very little wear, and most of that is under the stock line. There are a few very small spots of freckling.
Bore - 7/10 - The bore has no throat wear but enough pits that the rating had to be reduced. Borescope verified.
