I think that there is definately the possibility of a polymer lower being equally as stable as an aluminum one someday, if that day isn't already here.
We have tons of handguns that are polymer, why can't an AR lower be the same? There isn't much for the lower to do other than keep the trigger, magazine, and buffer in place and none of that takes a ton of strength.
So let's all take the tinfoil hats off and open our minds to the possibility of making a better mousetrap.
