This is a .270 Winchester featherweight barrel with a #7 sight ramp. Barrels made after 1956 do not have a date stamp, but the #7 sight ramp tells us this barrel was produced between the years of 1958 and 1963.
Bluing - 100% - The barrel has been reblued with no wear on the new finish.
Metal - Overall, this barrel is in very good condition. There are some minor scratches, nicks, and a few spots of very minor pitting, but no significant damage to the metal.
Bore - 8/10 - The bore shows some signs of wear. The rifling is bright and still clearly defined, but there is some slight throat erosion. Borescope verified.
