It is virtually guaranteed that no matter what sights the factory installed, some customers wouldn't know or care, they'd take the rifle home and be happy. Others would complain about and promptly replace those 'garbage factory sights' (blame the GunWriters for this) no matter what they were.
It is what it is and in some ways it's better than it ever was. Affordable scopes and sights are out there, pick whatever you like and be happy.
