This sounds like it would be a possibility but then you would lose the instant barrel change capability. The way the guys have it now you can swap back and forth barrels in a couple of seconds. Having to swap all the parts across from barrel to barrel would take considerably longer, and you risk the chance of small parts finding their way into the great beyond.
Just my $.02 so take it for what its worth.
You're right but depending on ATRS's answer I would have suggested sending the barrel minus takedown hardware for customers who're interested and when they become available send the extra set of takedown hardware (don't know if I'm making sense).
I 100% want to be able to swap the barrels in a pinch.
