We are going lighter and lighter and lighter on everything, BUT lighter and lighter done with no possible consequences and issues = $$$$$$ and most kiwi's want the good stuff at kiwi wages $$$ which really leads to a compromise. If we want an extra long service life out of things like suppressors, without big $ on exotic metals that cost a lot to buy and more to machine, then we need stainless materials and not ali but stainless is heavy. No free lunch there...
And to cut weight, there's only a certain amount of material you can remove before you are running the razor's edge. I think the OP has nailed it, how light is too light???
