Looks like just a sloppy factory weld, shouldn't be any more but cosmetic. I'd check the rifle over thoroughly for function, and alignment of the top rail. If price is right, it might still be a great gun, but I like my JS model 556's

Thank you for taking a look. The photo of the one without the weld is a JS model, as you no doubt noticed. I can already see why you favor them. I’m not a welder, but even I could tell it’s an ugly weld.

The weld at the top looks to be the worst part, the lower weld looks ok just from a cosmetic sense. Again, i'm sure its fully welded through, but this is why you see the quality fall off on some of the later models.
