What's the consensus on the above?
I would start with a 20" A1 pencil barrel for it's rifle gas system.
Cut it to 17" and put an adjustable gas block on it.
Use a JP low mass operating system and tune it to the ammo.
Any good muzzle brake and carbon fiber freefloat tube will do.
There will be no super lightweight AR that shoots as soft as that setup...
