Anyone have any idea? I can't seem to find details on the web.
Is it a specialized engraving machine? CNC? laser or tiny carbide bit?
Is the lower sprayed with some kind of finish after? I ask because I would think that after routing a few hundredths deep into an aluminum lower the color would be the natural silver of the metal, yet all that I have seen are black.
