I'm sure you have more experience than I do, and maybe I'll come around to your point of view eventually, but for large frame AR's I think it's best to just go ahead and start off with an AGB. There is more variability across manufacturers, more reciprocating mass, and more variability in ammo (across milsurp 7.62x51 to commercial .308 Win). Suppressor use also really affects things. Not always required, but dropping $100 on an SLR Sentry is a good way to let you tune your system.
