Not Just Metal Anymore: 3-D Printed Fire Control Groups

    Freedom Printing 3D (a channel I recently discovered) posted up a video early last month of a 3-D printed fire control group for the AR-15. I was surprised to see it, as my currently industry affiliation has always used metal parts – which prejudiced me against polymers in some capacities. It seems I should have looked harder at polymers which seem to be now functional as a fire control group straight off a 3-D printer.

    I am left to wonder… how much actually needs to be metal on a firearm outside of the barrel and bolt? How so will we get to that point?
