Making an AR-15 In the Wired San Francisco Office 391

An anonymous reader writes: Wired's writer Andy Greenberg writes about his experience fabricating an AR-15 lower receiver with the Ghost Gunner CNC mill. (That's the same device that was demoed in a Slashdot video earlier this year.) Greenberg points out that CNC millng isn't new, but reports nonetheless: "Aside from a single brief hardware hiccup, it worked remarkably well. In fact, the Ghost Gunner worked so well that it may signal a new era in the gun control debate, one where the barrier to legally building an untraceable, durable, and deadly semiautomatic rifle has reached an unprecedented low point in cost and skill."

      Its not an assault rifle. Those have been banned nationwide since 1986, and controlled/registered nationwide since 1934.

      Semi-auto rifles are legal in California, but the state heavily regulates cosmetic features for some reason(I guess to prevent feelzbad).
      AR15's can be made legally with proper care two different ways. Heck even after NY tried to make them illegal, those ingenious gun owners came up with a way to make them fit within the law there.

          Especially surreal when my wife learned to shoot same weapons in PRC at 12 years of age as part of the school curriculum, when around here we'd probably try to bring someone up on charges for doing that. Sometimes the gun control side sounds like the "abstinence only" education argument. Both seem to think lack of knowledge and superficial fixes will solve unrelated problems (i.e. sociopaths running amok).

          • I learned how to shoot a BB gun and 9mm as a teenager up in the hills above Silicon Valley in the 1980's. My friends and I ran around with the BB gun to shoot up the local wildlife (a woodpecker on top of a tree was unimpressed with our aiming skills and ignored us while we took potshots), but the 9mm required adult supervision to shoot up an empty oil drum. Friend's neighbors demonstrated the loading and shooting of colonial rifles. Those rifles were damn loud.

          Actually:
          "Assault Weapon" is the term made-up by gun-control spin doctors.
          "Assault Rifle" is a US military term for a fighting rifle in intermediate caliber (not pistol, not long action) capable of full-auto and/or burst fire.

          AR-15 is (as you know) not an Assault Rifle.
          M4 is an Assault Rifle.
          They function differently, but to most folks, they appear exactly the same. This is how gun-control types inject fear, uncertainty and doubt into the debate.

          The GCA banned the manufacture of transferable "machine guns" made after May '86.
          The GCA, therefore reduces the supply-side of the equation for transferable full-autos. Transferable M-16s cost in excess of $10,000, plus the $200 excise tax to transfer them from one owner to the next.
          An individual may legally own a full-auto capable weapon provided that they pass the strict NFA (National Firearms Act) requirements and that the weapon was made before May of '86.

          IANAL etc

          "You mean ownership of fully automatic weapons has been banned since 1986."

          No, he doesn't even mean that, because it's not true. One can't purchase a new automatic rifle, but you can (subject to state law) buy and/or own one which was registered prior to FOPA in 1986.
      • Way off. May 1986 was when the Hughes Amendment took effect, which was a part of the FOPA.

        http://en.wikipedia.org/wiki/F... [wikipedia.org]

        Fully automatic machine guns made after may of 1986 were at that point made illegal. Pre 86 machine guns are legal and transferrable so long as the ATF approves the transfer (and the gun is in the NFA registry, legal in your state etc).

        • Read the law and you'll see that they're all illegal; its just an exception writte in:
          See 18USC 922(o)
          (1) Except as provided in paragraph (2), it shall be unlawful for any person to transfer or possess a machinegun.

      It is not an "assault rifle" if it does not feature "A pistol grip that protrudes conspicuously beneath the action of the weapon." So depending on the grip that is attached to that lower, it is fine. Also, no flash suppressors, folding or telescoping stock, thumbhole stock, or grenande launchers. It also must not be a .50 BMG. The other option is to "permanently" attach a magazine that holds ten or fewer rounds of ammunition to the lower. If the rifle sticks within these parameters, then it is not an assault rifle.

      There are plenty of guns in California that are based on the AR-15, AR-10, and AK-47 platforms that comply with the law.

    The whole discussion about making your own guns, sort of reminds me of the day I realized how easy it was to make beer. So easy that any 14 year old can walk into any random supermarket and buy everything they need to make a couple gallons of beer for less than it costs to actually buy the beer (as it should be!).

    So all these prohibitions against selling alcohol to people under 21 are all pretty pointless, even kids without friends older than 21 can get their hands on unlimited supplies of the stuff with just a little thought and effort.

    So the latest hopla about making guns is sort of a resurgence of the zip gun culture. Only the results are probably more accurate on the whole.

        • by Orgasmatron ( 8103 ) on Thursday June 04, 2015 @12:58AM (#49837169)

          Just to clarify, making a gun is legal in the US, for anyone legally able to possess one.

          Provided that the gun in question is not automatic. Automatic means either that specially trained ATF technicians are able to coax it into firing more than once with a single pull of the trigger, or that it uses an open breech design.

          Open breech means that the gun rests with the bolt back. Pulling the trigger releases the bolt to move forward into battery, where the gun fires. Special parts are needed to cause the gun to stop after a single shot, and the easy removal of those parts makes the gun automatic, even if those parts are present.

          By contrast, in a closed breech gun, the trigger releases a firing pin or striker, starting the cycle. Special parts are needed to prevent the gun from firing again until the bolt returns to battery. Removal of those parts turns it into a nightmare machine, unable to reliably contain the pressure of the burning propellant.

          But a closed breech allows a disconnect in the action, requiring that the trigger release for each cycle. Without those parts, or with worn parts, the gun is an automatic. With those parts, it is semi-automatic, or self-loading. Or, a lever allows the user to select between the two, making a select-fire gun.

          To summarize:
          Open breech = automatic (by decree)
          Closed breech, disconnector = semi-automatic
          Closed breech, no disconnector, or selectable disconnect = automatic.

          Private ownership of automatics requires special licensing of the owner, and a special tax stamp paid on the gun. Those stamps have not been issued since 1986, but owner licenses are available.

          An ordinary person can also get licensed to manufacture automatics, but because the ATF won't issue a stamp for their product, they can't make an automatic for personal use. They can only use that license only to make guns for entities that do not require NFA stamped guns, which basically means military and law enforcement.

          Or, a person can get licensed to possess an automatic, and purchase a pre-1986 stamped gun. (Note that conversion devices like the Lightning like and the Drop-In Auto Sear [DIAS] count as guns here, as far as the law is concerned, even though they aren't guns.) Expect to spend about $10k getting started in this hobby.

          Luty's SMG is an open breech design. Don't even think about building one. But the book is a good read. It will help you understand how the Taliban held off two global super-powers mostly using guns they made themselves. In caves. With hand tools.

          Note 1: Conversion of an AR-15-clone is simple. Drill one hole in the right place, drop in one part, one spring and one roll pin, potentially swap out a few other parts, depending on the exact design of your clone, and you are done. But drill that hole without proper authorization and you are looking a 10 year felony sentence.

          Note 2: Since we are living in a post-Constitutional, post-Rule of Law era, any owner of a semi-automatic gun can be arrested and charged for NFA violations at any time. The ATF technicians have years of experience getting guns to double fire, and access to soft primers that will fire nearly unprovoked. They also have all the time in the world to tinker with your gun, and they get paid a salary to do it. They will get your gun to double fire at least once, and away you go.
