I have had these tabs open for awhile- a way to make your own firearms.

The first is a set of molds where you pour your own polymer AR15 lowers:

The second is Ghost gunner 2, a CNC machine shop for manufacturing firearms.

I'm pretty sure those are the molds McThag used when he did some posts on making polymer lowers a while back. Last summer? It took a few tries to get one that was usable.

I haven't seen anyone reporting on having used the DD Ghost Gunner, and I'm not 100% sure they aren't Vaporware (maybe ghostware is more appropriate here). It's supposed to be a light duty mill like the ones you can buy from Horrible Freight or Grizzly, only it's already set up for computer control, and has some setup features that make doing an 80% lower easier for a newbie. Because printing a plastic lower is cool, but there's a lot of history behind metal lower receivers, and you know if you make it right, it will just keep running and running. Plus, once you cut out your lower, it's supposed to be usable as a general purpose CNC milling machine.

Unless you have a vacuum tank, you WILL get bubbles in the polymer. and every bubbles is a source of weakness. Even then without knowing EXACTLY what resins they are using, I still wouldn't try it. As for the "Ghost Gunner" A machinist friend of mine bought one as a lark, he said it can do the job of his bridgeport, just not as fast nor as clean. Also if it's much larger than a .308 lower, it wouldn't fit in the machine.
