Disciple,
Yes, I see what you mean. That hole is not centered in the lug like all others on Google Images; there's more meat to the rear than the front. Might just be an Anderson design or it might be a mistake. Is the upper is being pushed rearward more than it should? Does this make closing the upper a tight squeeze at the buffer end?
You could file a bit off the forward edge to free it up a bit. I can;t see how that will change how tightly the two halves are held, or increase any slop, or reduce any meaningful strength in the bind Mega lowers have that screw in the pistol grip section you can use to tighten and stop the slop anyway.
Or, if a mistake you could send it back.
