You know, he's right

AR's ARE much better right now.  

No wonder Jeff Cooper didn't like them.  He died only just the AWB went away.  And it was only the beginning of the Forever War, GWOT.  He hated the round and the platform was forced to be stagnant.

Of course there is going to be advancements in the platform.  Both making the cheap stuff better and cheaper, and making the nice stuff REALLY nice.  Depending on what kind of a discerning rifle customer you are.  Hooray!  Capitalism.

And don't get me started on cheap and reliable magazines...

Sorry, Colonel, the poodle shooter round is gonna stick around a while.  And any replacement that you'd approve of is probably not going to be what comes next.
