I've wondered about laying up a CF or fiberglass lower. You might even be able to cobble together a cheap mold and use poured resin to do it.
Wouldn't be too much different than an injection molded, glass filled plastic lower though, which I've always thought could be made strong enough for use. It doesn't seem like the lower takes too many heavy forces:
- The recoil energy absorbed by the pins and to an extent through the buffer tube attachment.
- The stress on the firing mechanism from the bolt recoiling against the hammer. You could mold in bushings for the pins.
Are there any companies out there that make a plastic lower?
Carbon fiber might be an option. Hell, they are making motorcycle wheels out of it.
