Communities around the U.S. have seen shootings carried out with weapons converted to fully automatic in recent years, fueled by a staggering increase in small pieces of metal or plastic made with a 3D printer or ordered online. Laws against machine guns date back to the bloody violence of Prohibition-era gangsters. But the proliferation of devices known by nicknames such as Glock switches, auto sears and chips has allowed people to transform legal semi-automatic weapons into even more dangerous guns, helping fuel gun violence, police and federal authorities said.

The (ATF) reported a 570% increase in the number of conversion devices collected by police departments between 2017 and 2021, the most recent data available.

The devices that can convert legal semi-automatic weapons can be made on a 3D printer in about 35 minutes or ordered from overseas online for less than $30. They’re also quick to install.

“It takes two or three seconds to put in some of these devices into a firearm to make that firearm into a machine gun instantly,” Dettelbach said.

    I still stand by this being a clear indication of being unfit for gun ownership though.

    I appreciate that you’ve been a good faith interlocutor so far, but I wanna push back on this just a little more.

    The current rules governing SBRs in the United States were established in the 1930s in anticipation of an outright ban on handguns. The thought was that “sawed-off” or short-barreled rifles would be a way for people to circumvent the ban. And, because the law enforcement thinking at the time was distinctly classist, the mechanism for keeping these guns out of the hands of criminals was not an outright ban but a ludicrously high tax, in the neighborhood of $4500 in today’s money.

    But that ban on pistols never materialized. So now, we’re left with a nearly 100 year old vestigial law that doesn’t really serve much of a purpose: short-barreled rifles aren’t any more deadly than full-length rifles (they tend to fire the same bullet louder and slower), and they aren’t any more concealable than handguns. There really isn’t an obvious public good that is served by these laws, and their enforcement gives away that the ATF understands that on some level: basically no one is ever charged for just having an unregistered SBR, it’s almost always a rider-on to a different crime or an excuse for a cop to fuck you up if they don’t like you.

    Enter pistol braces. Ostensibly, they are a device that assists shooters that have lost the use of one of their hands to stabilize an AR pistol with the forearm of their one good hand (and to be clear, they serve that purpose well). However, some people notice that they happen to be shaped in a way that provides a lot of the function that a stock would, and begin using them on AR pistols as a way of getting the ergonomics and aesthetics of an SBR without paying the additional tax and waiting months for approval.

    And for a really long time, the ATF was okay with this. Pistol braces were specifically allowed. That was, until a few years ago, the ATF decided to… Change their mind? “Re-interpret” existing rules was I think what officially happened. No new laws were passed, no democratic process took place, and no clear and present danger was being addressed. They just kinda decided “Hey these are illegal now, you have X days to comply”.

    Does aquiescing to that “interpretation change” have anything to do with being a responsible gun owner? To my mind, whether someone complies with that or not says more about their obideience to authority / fear of consequences than it does their responsibility or danger to society. There is no inherent moral good to following the law, and history is filled with responsible people who flout pointless or harmful laws.

      You know, I would push back on this a little bit. It’s not really a necessity that they’re more lethal than rifles, and more concealable than handguns, they can still do plenty of damage while occupying the middle category.

      Handgun cartridges usually travel at below the necessary 2100 fps required to create permanent hydrostatic wound cavities, which means they need more shots on target to do a similar amount of damage. Unlike sawed off shotguns (which I think are registered as destructive devices? idk), which tend to be unwieldy to fire, especially at range, an SBR can be fitted with a suppressor, and has the potential to fire hotter and lighter loads capable of defeating level 3+ body armor, unlike a handgun. Probably not at the same time as a suppressor would be used, but, dealer’s choice, I guess. All of this is in a package that can potentially be carried, somewhat easily, in a large to mid-sized coat along with spare magazines. Unlike a normal rifle, which might require something like a larger trench coat, or poncho, or what have you. SBRs are also going to be much more usable at range compared to your conventional handgun, it’s sort of along the lines of an advanced PDW in that respect, with maybe a slightly larger form factor.

      So, if we’re kind of, thinking about the possible attack vectors that this could be used for, I think it’s understandable why federal law enforcement might be a little bit more concerned about this, compared to long rifles, handguns, or shotguns, which occupy more distinct niches that are perhaps a little bit easier to safeguard against with conventional tactics. No comment on the pistol brace thing, that was kinda stupid, but the SBR ban doesn’t make absolutely no sense, as long as you’re evaluating it from a very particular perspective.

        A perspective that can’t see bullpups, apparently
