You Can't Print a Gun If You Have No 3D Printer

FatLittleMonkey writes "You may recall Cody Wilson's project to create a 3D printed gun, mentioned previously on Slashdot. Well, the Defense Distributed project has suffered a decidedly non-technical setback, with printer manufacturer Stratasys revoking the lease and repossessing the printer (presumably prying it from plastic models of Cory's cold dead hands). According to New Scientist, the manufacturer cited his lack of a federal firearms manufacturer's license as their reason for the repossession, adding that it does not knowingly allow its printers to be used for illegal purposes." Homemade firearms are not (in the U.S.) per se illegal on a federal basis, though states have varying degrees of regulation. It would be helpful if anyone more conversant with firearms law than me can point out what law or laws this project might be breaking.

    No, you don't. You only need a license if you are manufacturing arms FOR SALE. People make homemade guns for fun all the time.

    False:

    Q: Does the GCA prohibit anyone from making a handgun, shotgun or rifle?

            With certain exceptions a firearm may be made by a non-licensee provided it is not for sale and the maker is not prohibited from possessing firearms. However, a person is prohibited from assembling a non-sporting semi-automatic rifle or non-sporting shotgun from imported parts. In addition, the making of an NFA firearm requires a tax payment and approval by ATF. An application to make a machine gun will not be approved unless documentation is submitted showing that the firearm is being made for a Federal or State agency.

    Thing is, federal firearms laws are mostly about the sale of firearms. You can make them for your own use all day long and not break the federal law. But if you plan to sell them, you need to get serial numbers for them. And for that you need to register.

    An automatic rifle is not a machine gun according the the law, afaik. They are a separate class of weapon.

    I believe that an "automatic rifle" means an auto-loading rifle which is the technical term for a "semi-automatic" weapon - i.e. the vast majority of rifles legally sold for civilian use in the modern area.

    A "machine gun" is a fully automatic weapon and those are illegal for private individuals to own, period, unless they're made before 1986 and you've paid for a Federal "tax stamp," which I believe is $200 (I imagine they're still illegal for private citizens to own in certain jurisdictions; obviously, Kalifornia comes to mind). Corporations as well as certain manufacturers and dealers, however, can own fully automatic weapons made after 1986 but obviously certain rules apply.

    The technical term for a "sawed-off" shotgun is an SBS (short-barreled shotgun) which is a smoothbore longarm with a barrel less than 18" in length (or, I believe, a total length - including the stock - of less than 26"). These also require a $200 "tax stamp" to the Feds.

    Here's some additional useful info, from here:

    "Sporting" Purposes

    Here's where things get a little tricky. Some rifles, such as the Saiga line, are imported for sporting purposes in a particular configuration. Generally, that means that do not incorporate any of the "evil" features that are typically associated with so-called "semi-automatic assault weapons". Chapter 27 of the Code of Federal Regulations Section 478.11 defines these SAWs. You can read the law, here. Specific examples of these features include:

    - High capacity (greater than 10 round for rifles, 5 rounds for shotgun) magazines
    - Pistol grip attachment
    - Folding buttstock
    - Muzzle device/attachment (to include a threaded barrel capable of receiving a device)
    - Bayonet lugs

    If your rifle or shotgun incorporates those features, it no longer is considered "suitable for sporting purposes".

    Assembling Semiauto Rifles and Shotguns

    If your rifle or shotgun is subject to 922R, you must now make sure that it is in compliance with the regulations governing the assembly of semiautomatic rifles and shotguns. That is covered in Title 27 Chapter 1 Section 178.39. Click here to see the text of the law. It states :

    (a) No person shall assemble a semiautomatic rifle or any shotgun using more than 10 of the imported parts listed in paragraph (c) of this section if the assembled firearm is prohibited from importation under section 925(d)(3) as not being particularly suitable for or readily adaptable to sporting purposes.

    Paragraph (C) defines the following parts as "countable" under the law:

    (1) Frames, receivers, receiver castings, forgings or stampings *
    (2) Barrels *
    (3) Barrel extensions
    (4) Mounting blocks (trunions) *
    (5) Muzzle attachments *
    (6) Bolts *
    (7) Bolt carriers *
    (8) Operating rods
    (9) Gas pistons *
    (10) Trigger housings
    (11) Triggers *
    (12) Hammers *
    (13) Sears
    (14) Disconnectors *
    (15) Buttstocks *
    (16) Pistol grips *
    (17) Forearms, handguards *
    (18) Magazine bodies *
    (19) Followers *
    (20) Floorplates *

    These 20 items are referred to with the term "compliance parts". There are lots of other components that go into a weapon, but there are the only ones that count in terms of complying with the law.

    Sure. You SAY it's not illegal. How confident are you in that? Are you willing to go to jail to get the opportunity to prove it?

    I don't say it's not ilegal, 18 U.S.C. 922(o) and (r), 26 U.S.C. 5822, 27 CFR 478.39, 479.62 and 479.105 does.

    Gun control law is illogical, inconsistent, and subject to huge penalties and stigmas (do you want 'arrested on weapons charges, 2012' on your resume, even if you are cleared?).

    FYI, you are only legally required to list convictions on job applications.

    There's a reason companys like eBay and craigslist shy away from allowing even very obviously legal items--even gun accesories like holsters--to be traded on their sites--our lords at the ATF have no sense of humor.

    Well, you would have a point there, if your little anecdote had an ounce of truth to it.

    In the context and the language of the time, ``well-regulated militia'' simply meant one trained to the firearm and other drills of the time.

    Moreover, the membership of the militia is quite a bit larger than most people believe:

    http://uscode.house.gov/download/pls/10C13.txt

            The militia of the United States consists of all able-bodied
            males at least 17 years of age and, except as provided in section
            313 of title 32, under 45 years of age who are, or who have made a
            declaration of intention to become, citizens of the United States
            and of female citizens of the United States who are members of the
            National Guard.
                (b) The classes of the militia are -
                    (1) the organized militia, which consists of the National Guard
                and the Naval Militia; and
                    (2) the unorganized militia, which consists of the members of
                the militia who are not members of the National Guard or the
                Naval Militia.

    and just in case someone thinks there're weasel words in section 313 of title 32:

    (a) To be eligible for original enlistment in the National Guard,
    a person must be at least 17 years of age and under 45, or under 64
    years of age and a former member of the Regular Army, Regular Navy,
    Regular Air Force, or Regular Marine Corps. To be eligible for
    reenlistment, a person must be under 64 years of age.
    (b) To be eligible for appointment as an officer of the National
    Guard, a person must -
    (1) be a citizen of the United States; and
    (2) be at least 18 years of age and under 64.

    Per the ATF: "For your information, per provisions of the Gun Control Act (GCA) of 1968, 18 U.S.C. Chapter 44, an unlicensed individual may make a “firearm” as defined in the GCA for his own personal use, but not for sale or distribution."

    So as long as you make it for yourself and don't sell it or give it away, it's Federally legal.

    It was tested.
    When Glock first came out there were articles full of "The Plastic Pistol" that bad people would use to get past security.
    The spring is big. the barrel is a very large chunk of metal that is hard to miss.
