This is a Featherweight barrel for a pre 64 Winchester model 70 rifle, chambered in .308 Winchester. This barrel is not date-marked, but based on the #7 front sight ramp, it was manufactured between 1958 and 1963.
Bluing and Metal - 85% - This bluing on this barrel has some wear, mostly from where the stock contacted the barrel. There are a few very shallow scratches and some freckling/shallow rust near the muzzle.
Bore - 7/10 - The bore has no throat wear but enough pitting to reduce its rating. Borescope verified.
