that you don't have to 3D print every single component... Just one. The receiver. All the rest of the components are just parts and are not regulated.

And that one does not necessarily require those same tolerances...

A barrel, a breech, or a bolt are not a gun. They are PARTS. A firearm ITSELF is the serialized receiver itself. Which, depending on design, may not receive ANY of the heat and pressure of firing. Take the ever popular AK-47. The serialized receiver is made out of thin stamped metal. CHEAP and WEAK compared to the barrel or the bolt. But it doesn't have to be because its' location simply is not susceptible to those stresses, pressures, and/or temperatures.

You could 3D print an AK receiver quite readily, then drill the holes in it with ample tolerances as the rifle itself is DESIGNED to be a bit loose and sloppy.

  • that actually work. Their accuracy is just not sufficient. Tolerances need to be ten-thousandths of inches. Also, commonly available 3-D printers cannot handle high melting point metals which are... more

      Thus my use of "on the way." I definitely understand the challenges (I'm pretty serious about shooting, reload my own ammunition for my long-range rifles, etc.) involved in "homebrew" firearms. I... more
