'bout the only thing you posted that I agree with. since you asked.
All the rest of that spendy, trendy, stuff you posted costs money that would be better served in training and practice. I'll take a shooter with a stock RRA Entry Tactical with a couple of training classes and a few thousand rounds fired under his belt over any gunshop commando with the same amount of money sunk into his gas-piston, jesus-jizzed-on, heavy-barrel, whirlygig rifle and no goddamn idea which end the bullets come out of.
