one thing for damn sure it won't look like a m-4 lower. "LOL"
i don't think the finished product will be much if any lighter than its metal counterpart . and it probably won't be quite as strong --but it could be strong enough and much less expensive.
if it ain't strong enough to withstand bayonet drills and some serious butt-strokes to some hard surfaces it ain't strong enough--
i kinda get a laugh at all the mall ninjas talking about "carbon fiber" lowers--
you could make a very good carbon fiber lower and it would be plenty strong and a bit lighter than aluminum.
by the time you get one cooked up you going to have to ask "space technology" prices for it too. real carbon fiber technology ain't cheap--
an old joke about vulcan carbon fiber is they would drop a charcoal brick in every vat of plastic --just so they could say carbon--LOL!
With all the brilliant and inventive minds out there... Someone has improved on it and will be selling it to DOD soon if not already...
