Metal - Overall, this barrel is in excellent condition. There are a few minor marks of wear.
Bore - 7/10 - The rifling is bright and strong throughout the length of the barrel, showing minimal signs of use. There is some very minor pitting in the bore but it took the borescope to find it and is truly very minor. Borescope verified.
