But let's put the cost in perspective. Your average entry-level AR-15 is around $800. Add a UBR stock: +$250, add sling swivel hardware $80, add BUIS $100 (minumum), add MIAD/TG $50, add ambi controls $80, add float tube / top rail system $200. Just considering those changes you're at about $1500.
Except you've got a top notch adjustable stock, iron sights front and rear, the barrel twist of your choice, and four rails (if you want them) instead of a plastic handguard with a top rail. You are also almost a pound lighter than the basic ACR and still $900 shy of the AIM Surplus retail price.
The piston is basically an AR180 system. There isn't anything particularly new there that I see adding $900 worth of value. The quick-change barrel is a nice feature; but not one I really need and if the basic rifle is going to be $2,400, I'm afraid I'll be able to buy a new upper cheaper than any future conversions (when/if they are available).
