? how to spot authentic Rock River parts ?

I just supposedly bought a 0550 Rock River upper 20" varmint. Its supposed to be a 1:8 twist. I'm trying to confirm w/in myself, that this all what it was advertised to be.
I see nothing engraved on the barrel. The aluminum forearm tube is still on, but w/ a flashlight, I see no engraving or any marks. I took the bolt out, and see no marks or engraving on it. So how can one tell authentic parts from not? The only ID I see is on top of upper receiver, it says rock river arms. ??
