Alright was helping a buddy look over all the parts he collected for his build and I peeked down the barrel, where the gas hole is drilled inside the barrel there is kind of a lip of material.

I am assuming its pieces that didnt come off when the hole was drilled. We tapped it with a cleaning rod and most of it came out but there is a still a bit of junk left around the edge of the hole.

Sorry pics didnt turn out, I will try again tonight.

So any way the question is should he worry? I dont remember ever seeing that on any of my builds, but I don't even remember looking...

Don't worry about it. If the pieces are actually in the hole, or on the inside edge, escaping air will start to push them into the port, then the firing gasses will blast them down the tube.
