M98 Mauser Barrel Carbine, 19 inch 7x 57mm

I liked the first barrel I ordered and ordered 2 more. The pitting was isolated and well defined in small spots. I received the other 2 today, and they had less pitting than the 1st. The pitting was external only and the bores are perfect and unfired with no pitting. I haven't fired them yet but expect them to be fine.
