Purely as a practical matter, how long do you think it will be before someone takes an Othermill or similar portable CNC machine, and builds the jigs and writes the code to make finishing an 80% receiver or 80% frame as simple as clicking a button with your mouse?

I'm not sure about the Othermill, but people have adapted the $500 Harbor Freight bench-top mill to CNC. The data files for AR-15 lower receivers are all over the Internet. The writer's "one button" scenario is possible with large production CNC equipment, but the garage shops require more setup steps.

Hell imagine turning out hundreds of suppressor equipped STEN GUNS complete with magazines! Modular, cheap, simple, reliable, effective. The idea has got to give the liberal’s inner totalitarian a case of the screaming heebie jeebie’s. 8*)
