Norinco M4 uppers

[alberta5492]

Does anyone know if a complete Norinco M4 upper will go onto a Bushmaster XM15-E2 lower without any problems? I don't see why it wouldn't, but thought I'd ask around. I have a 16" upper on it now, but llike the idea of having a 10.5" upper to swap back and forth.

Thanks

Providing that the Norinco upper is within spec there should be no issues mating it to your Bushmaster lower receiver.
