This is a .220 Swift stainless steel standard contour barrel from a 1948 Model 70 rifle.
Bluing and Metal - The bluing is in excellent condition with a few spots of minor wear. There is no notable damage to the metal.
Bore - 9/10 - While these stainless barrels generally do not get pitted, a lot of the .220 Swift barrels show significant throat erosion - this one does not. There is a bit of throat wear; it's minor, resulting in grading of 9 out of 10 for the bore.
