Your upper was probably assembled from different parts on a replacement upper receiver. Previous owner probably had the number laser engraved on it.

...in keeping this a HK416 picture thread

I bought the upper from another HKPro seller named @landlocked. He has had a bunch of them come through his hands and he says its all legit.

They very well may be 100% HK parts, there's nothing wrong with that but an AH barrel with an AE bolt and an unmarked receiver probably isn't the way it came from the factory.
