Digging Into the Legal Status of 3-D Printed Guns

jfruh writes "Defense Distributed, a U.S. nonprofit that aims to make plans for guns available owners of 3-D printers, recently received a federal firearms license from the Bureau of Alcohol, Tobacco and Firearms. That license doesn't cover semi-automatic weapons and machine guns, though — and there are questions about whether the legislation that defines that license really apply to the act of giving someone 3-D printing patterns. Experts on all sides of the issue seemed to agree that no clarification of the law would happen until a high-profile crime involving a 3-D printed weapon was committed."

    In what way is using a 3d printer different than me making a semi-AK out of a sheet metal and supplies from homedepot?

    I just don't see how it matter what tech made the gun parts. This seems more like attention seeking than a real concern. Home manufacture of semi-auto long rifles is federally speaking totally legal.

      Actually 'Rifle Barrels' under a certain length are regulated by the National Firearms Act (NFA) and enforced by the ATF. The NFA defines NFA "firearm" as: A shotgun or rifle having a barrel of less than eighteen inches in length or any other weapon, other than a pistol or revolver, from which a shot is discharged by an explosive if such weapon is capable of being concealed on the person, or a machinegun, and includes a muffler or silencer for any firearm whether or not such a firearm is included in the foregoing definition.[3][4] http://en.wikipedia.org/wiki/National_Firearms_Act -Casey

      Only when installed on the gun, or when you have the gun and the barrel and intent.

      Otherwise all pistol barels would be illegal as they could be used on rifles with a little machining.

      While making the whole gun from scratch is hard, it's not really that hard if you use an 80% complete receiver/frame. The ATF decided that a chunk of metal becomes a "gun" when more than 80% of its production is completed. There's many companies that sell, for example, 80%-complete AR-15 lower receivers. Legally, it's a chunk of metal but you can do some basic work to finish it up.

      For example, here's some instructions. You basically need a drill press (about $100 from Amazon or $70 from Harbor Freight), some drill bits (and maybe an endmill bit) which are available for cheap at hardware stores, and some basic supplies like wood, a permanent marker, etc. 80% lowers are about $80 for small volumes but get cheaper in bulk. You can buy the jigs that tell you exactly where to drill for about $120 and they can be used to produce as many lowers as you want (they don't really wear out).

      The fire control parts, trigger, grip, etc. are about $80.

      For the "complete" gun parts, it's about $750 (that includes everything except the machine tool parts -- it includes the barrel, stock, fire control parts, etc.).

      Operating a drill press isn't terribly hard and one can be trained in a few minutes. After that, it takes a few hours to make the needed holes and the jig makes it pretty idiot-proof. Putting the rifle together isn't terribly hard (and there's lots of information online that details how to do this) and you're good to go. Basically, it's less than a day's work and less than $1,000 for the first rifle (with the cost being amortized if you make any more).

      Certain groups have "build parties" where you put your 80% lower into a CNC mill and press "start". Since you push the button, it's you who are making the gun (as opposed to the machinist) and thus is legal. It can make it in about 8 minutes.

      Sure, making your own rifle out of metal isn't trivial like it is with a 3D-printer (where you just hit "print"), but it's not that hard either.

  2. Semi-automatic weapons by danb35 · · Score: 5, Informative

    Yes, if it's a manufacturer's FFL (TFA didn't specify, but it seems to be the case from context), it does cover production of semi-automatic firearms as well as pump-action, bolt-action, revolvers, and most others. Machine guns are separate, being (as TFA notes) covered by the National Firearms Act, not the Gun Control Act. For right now, federally speaking, domestically-made semi-automatic firearms don't have any special or unique status. If Senator Feinstein gets her way, of course, that will change, but it's the case currently.

  3. Various bits of FUD correction. by nweaver · · Score: 5, Informative

    a: An FFL7 (which is what Defense Distributed got), once they complete some additional tax paperwork, allows them to make and sell semiautomatic rifles like any other manufacturer. And there are lots of small manufacturers these days. Heck, there is one in Napa, CA, if you want a fine, vintage 2013 AR-15 with "Made in Napa, CA" printed on the side.

    b: Plastic AR lower receivers are old news. There is a lot of panic buying of AR rifle components thanks to Dianne Feinstein's salesmanship, but the plastic lowers are readily available.

    You can even get a 5-pack for $400!.

    Distributed Defense's sales, if any, are going to be those wanting to support their R&D, as there is no way they can compete with the existing aluminum lowers, let alone existing plastic ones, on price or quality for a given price.

    c: There are a lot of businesses which legally help you make your own gun. EG, you buy an 80% lower (a not completed lower receiver) which the ATF does not consider to be a gun and then you finish it yourself by renting some milling machine time and doing it yourself. Until its finished by the purchaser, its a paperweight, not a gun.

    d: Some guy has even managed to do a home-made polymer lower using molding techniques.

    Semi-automatic rifles are under CGA. It's a shame that so many IT professionals who like to consider themselves intelligent and educated are bloody ignorant morons when it comes to firearms (and mostly should STFU).

    Let me give you some basics:
    - single shot muzzleloader = load from the front, and fire, then must reload every round).

    - manual chambering (bolt, pump, lever, revolvers) = a mechanical action must be done to eject the old cartridge shell and chamber a new round, often this cocks the hammer/firing pin so the trigger can be pulled and one shot fired.

    - single action revolver = cylinder is manually rotated by cocking of hammer. One shot fired, then chamber must be manually cycled.

    - double action revolver = cyclinder is manually rotated by pulling of trigger, and fires a round. One shot fired for every trigger pull.

    - semi-auto action = gas from bullet powder exploding is used to eject the empty cartridge shell. A spring is used to return the slide back to position, re-cock the firearm, and chamber a new round in the process. One trigger pull = one shot. (AR15s, "Assault Weapons", etc are all semi-automatics).

    - automatic = gas from bullet powder exploding ejects cartridge, slide return re-cocks hammer, chambers a new round and then disengages hammer firing the new round. Repeat (or do/while ammo loop). An "assault rifle" M16/M4, and other fully automatic guns fall under this classification. These are the rifles which fall under the NFA.

    Dang...can we computer peeps get some common sense?

    Many would argue that gun violence has become more pervasive, and I'd have a hard time arguing against that statement.

    Why? It's quite easy to argue against such a statement: according to FBI crime statistics gun-related homicide rates are at their lowest level since 1964 (scroll down to get the normalized rate-per-100,000 people) and have been declining for years. You can get the raw data from the FBI directly, if you prefer.

    By any objective measure, gun-related homicide in the US has decreased significantly even as the number of legally-owned guns in the country has increased. People may perceive that gun violence is increasing (and it may well be true in certain localities in the country), but overall that's not the case.

    According to crime records, while there's been some year-by-year variation in the number of mass shootings and victims, overall the trend has been constant since at least 1980. Despite the enormous media attention they get, they are statistically very rare. Are there too many? Absolutely.
