Well, you can make everything with a CNC machine anyway, but you'd need the exact measurements for everything, which would be pretty hard with the trigger mechanism. A 3D printer could do all of this, but out of materials that are weaker than metal; what a danger to the public! rolleyes.gif

Printing the lower could lead to a person to make a full auto trigger sear, which would be highly illegal. Still, not very practicle as many have pointed out.

Even without a full-auto sear this is highly illegal. Isn't the whole point that only the lower needs to be given a registered and documented serial number?

Actually, a fully automatic AR-15 trigger mechanism requires something like two new parts in the trigger mechanism and one new one on the bolt. It's pretty hard to get one of them to do fully auto, unless you're a gunsmith.

If you can legally own a firearm you can legally make your own. MAKE not sell. You just have your own serial number/

Actually at least in the US you can legally make a gun yourself, including the lower receiver. However, it is illegal to then sell it without a license. It is also illegal to make a gun you cannot legally own.

Edit: beat to it

All this worry over plastics when high density ceramics have been studied by the government for years for use in weapons including barrels. Source
And I'd be lying if I said I understood a fraction of what is contained within the source.

That's not my point. They still have to find every other part to create a functioning firearm, the most critical of which are extremely difficult to (legally) acquire in Europe. The barrel, in particular, is itself a registered item in many EU countries.

No. If you manufacture the registered part of a firearm, in this case the lower receiver, you can legally build a fully automatic weapon around it. What you cannot do is register the weapon with the ATF; the moment it gets a serial number, it becomes a post-86 machine gun and subject to applicable law.

On second read, this is a complete legal grey area. One must be a Class 3 licensee to manufacture machine guns, but a self-fabricated weapon is not serialized. Not sure it's worth the potential trouble of an overzealous ATF agent.

Take a second mortgage to buy a 3d printer in order to make a unreliable gun part or grab a kitchen knife?
The funny thing is that the #d printer is treated like a magical device with which you can make stuff. Where the making of stuff is the important thing. Banning 3d printers because you can make barely functioning parts with them is as stupid is as banning rocks because you can bash it against another rock and make em smaller and easier to throw. (unless you have flint which as far as i know is worse than WMD's)
We're a long way from a 3d printer that can make usefull everyday crimecomitting stuff.

See last weeks CSI episode? It had this sort of thing in it. An assassin used one time use, disposable printed guns (that break after 1-2 shots) to assassinate people so the guns were untraceable.
