When you say that the barrel nut is smaller do you mean that it does not allow the barrel to be secured to the receiver or that the outside diameter of the barrel nut is smaller than the one supplied.

The 2 barrel nuts are not interchangeable so there is no need for them to be of similar size.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals....

"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
