Oval barrel pin hole

Looking at a new Century Yugo AK at gun store and noticed a small gap at the front of the barrel pin hole. Is this a problem? Gap was on left side of rifle the right side was ok no gap.

It's a DCI receiver with the new barrel, wood stocks, one of the newer builds they are selling. Everything else is in great shape and all straight. Finish is even and wood is tight.

What gives about the small gap at the barrel pin?

Likely caused by runout or drill bit wandering when drilling for the 7mm barrel pin on the virgin US barrel. Might be OK but I would just walk away. There are 1.000's of AK's to choose from.
