Scratches and marks in AR chambers..... What is excessive and what is OK?
#2
The obvious scratches in the bottom image suggest careless tool handling by the person who cut the chamber.

I hope, however, that one of our members who has experience in metallurgy or inspection can give us a read on the first two images. I have only a lttle experience in this area, but they suggest that the barrel steel itself has cracks and inclusions. That could be a safety issue.
