Some friends of mine have a 5-axis C&C machine, applied and received their class 7 FFL which pretty much they can build anything except for destructive/explosive devices. They started producing full AR-15's from the lowers, hand guards, uppers, et al..They asked if I would do their pictures for them since I'm into photography... I'm into Astrophotography, not product photography, but figured it might be good experience.
Feedback? Don't be afraid to be brutal if you need to.
