Gentlemen, I am very new to the High Road and have really gotten into the black rifle club. My questiion is this. I just bought a complete Rock River upper via an advertisment in a magazine( a dealer not Rock River Arms). When i received it, there are no markings touting the Rock River brand name.It is stamped 5.56 and has a 1/9 twist. How can one know if it's the real deal or some crap? Thanks for the great insight on sport shooting!
