Maybe a bad example of FN quality?

This barrel arrived with an open bag that appeared that it should have been sealed. The gas port was undersized for the spec. There was a large burr for the gas port inside the barrel that could be seen with the naked eye looking down the barrel. I'm sure FN quality is usually better, but this one ended up getting returned. I decided to go with another brand with a good reputation.
