AR15 Quick Change Barrel Idea.

Well, just mount the optic to the handguard then. That is the stable part in this whole equation, right?

Until it needs to be removed for a barrel swap.

Just buy an LMT.

Torque specs exist for a reason, the barrel nut spec is 30-80 ft.lbs. I could see a loose barrel nut affecting headspace as well as alignment of the bolt lugs to the mating receiver extension lugs. No thanks, there are alternative quick change systems that work out there.

We are talking about swapping barrels, the optic attaches to the upper receiver. I'm in the understanding that swapping a barrel would move the zero, possibly a great deal in between changes. Aluminum threads in the upper would also rapidly wear out as well as the hole machined for the barrel to fit snugly into.

I understand. I am just saying if he was to have 2 complete uppers, this would allow him to swap a single optic between the two.
