I had recently read a opinion piece wherein the author was suggesting that certain firearms could be reclassified to Class 3 Firearms and that doing so was not violating the Constitution, but would require registration of such firearms.

Is this feasible, and could a reclassification be done by executive order (similar to the Executive Order on bump stocks)?

ETA: this question never mentions reclassification of semi-automatic to fully automatic (as has been the basis of some answers). Some class 3 weapons are not full automatic but appears to be so classified for other reasons ie short barreled shotguns or cane guns)

  • Given the edit: if you're asking us to brainstorm what guns could be banned due to length, that's probably not a very good question here. As we've seen from the bump stock ban, the political imperative comes from a.... massacre. So unless you can predict that some other massacre will involve a certain kind of (short) guns that's skirting the existing classification, so would be easily bannable, you''re probably asking for a wild guess.

  • And it would probably be wise to detail what "certain firearms" you heard might be thus banned. Asking answers to guess what you've read is not exactly upvote-worthy. Commented Jun 14, 2022 at 2:14
  • @Fizz Are you conflating "banned" with "reclassified"? There are a host of firearms that are classified as Class 3, and not "banned". But to address your "certain firearms" request, the opinion piece was referring to "high velocity, massive trauma inducing weapons" The author was not suggesting "banning" weapons, rather that certain weapons (by way of classification) might have additional regulation requirements.

  • I'm aware of the distinction, but reclassification often sends the prices through the roof by making new guns of that class unavailable. So it's a fairly strong limit on the supply, quasi-ban. Commented Jun 14, 2022 at 17:56
  • As for "high velocity, massive trauma inducing weapons"... it is pretty vague. The might be talking about .50-cal rifles, which are banned in a few states.. or about the AR-15 class, which would be much more difficult to ban. In any case, there's no basis in the classification for the bullet velocity. Trauma is perhaps remotely debatable given that "destructive devices" are banned, but it would be a huge stretch to apply it to rifles. Commented Jun 14, 2022 at 17:59

The National Firearms Act(NFA) is quite specific as to what constitutes a class 3 firearm. The president cannot change this unilaterally, because the US constitution expressly gives Congress the ability to pass and legislation.

Executive orders are orders to the executive agencies to act in a specific way within the bounds of authority that congress has given them. They have no power unless they are backed by some law.

The NFA defined a "machine gun" as a firearm that fires more than one round with a single pull of the trigger. Bump-stocks and forced-reset triggers are mechanisms that cause the recoil / action of the gun to release the trigger, so that the user automatically pulls it again when the gun resets.

The ATF argues that such things are effectively machine guns, as they fall under the spirit of the law: you pull your trigger finger back and the firearm discharges multiple rounds.

Proponents of them argue that they technically aren't, because the trigger resets in between rounds.

The question of whether the spirit or the words of the NFA should be enforced is a matter for the courts to determine. However, the ATF has a good-faith argument that they are machine guns under the actual law.

If the president issued an executive order saying "Semi-automatic rifles are now machine guns under the National Firearms Act," this would be blatantly violating both the letter and spirit of the law. There is no chance any ATF actions enforcing this order would be upheld by the courts.

    I hear what you are saying, however Trump "banned" bumpstocks by Executive Order (that had previously been permitted by ATF). This action modified the National Firearms Act definition of the classification. No change in the law actually occurred, however the how the law was applied did change. Only years later did Congress act to specify the ban on bumpstocks.

    You have to have standing to challenge a government action. That means you have to be convicted of violating the law, with all attendant consequences, in order to challenge a law. The EO and ATF enforcement were geared toward retailers, who are not going to risk their entire business over a low-volume accessory like a bump-stock. Commented Jun 12, 2022 at 19:38

    It's not clear which specific firearms you're asking about, but in my hypothetical of the ATF declaring all semiautomatics to be machine guns, that would be an absolute violation of their duty to uphold the laws as written, and it would cause substantial financial damage to the retailers. People would absolutely violate it so that they could take it to court. Commented Jun 12, 2022 at 19:43

    The top line answer of "no" is contrary to the body text of the answer which specifically states that it can and has been done lawfully. This answer sets up a straw man argument about reclassifying all semiautomatic weapons which isn't what the question asks.

Can US President reclassify firearms by executive order?

Is this feasible, and could a reclassification be done by executive order (similar to the Executive Order on bump stocks)?


@user1167758 is not wrong in saying that "Executive orders are orders to the executive agencies to act in a specific way within the bounds of authority that congress has given them. They have no power unless they are backed by some law."

But, classification of particularly firearms in a particular class is one of the things that Congress has given the executive branch the authority to do within the bounds of the definitions provided in the relevant statutes.

An executive order is one means by which a new regulation is enacted. There is a process that has to be followed to change a regulation under the Administrative Procedures Act, but it can be done.

There are always a significant number of cases in which a firearm could legitimately be classified in more than one possible class and when that is the case, the executive branch has discretion to determine that a predecessor administration made the wrong call, if the new classification can be supported by rational arguments from the facts.

As a practical matter, regulations are updated and revised on a daily basis, and while past regulatory determinations aren't frequently revised, it isn't something terribly exceptional either.

For example, in the 1990s, the U.S. government decided that its historic regulations that is used for determining when entities were classified as partnerships for tax purposes and when they were classified as corporations for tax purposes, had become an unworkable, confusing mess that didn't advance legitimate policy goals and overhauled those regulations entirely.

Similarly, from time to time, the U.S. government updates lists of pollutants, endangered species, and controlled substances based upon standards provided by statutes and sometimes changes classifications used for that purpose.

This doesn't mean that any particular firearm is a good candidate for reclassification, and the question doesn't identify any particular firearm that would be reclassified, but surely there are some such firearms, and the bump-stock reclassification is one example of such a firearm.

For example, a Class 3 Firearm (per the link in the question) includes:

According to the NFA, a machine gun is defined as "[a]ny weapon which shoots, is designed to shoot or can be readily restored to shoot, automatically more than one shot without manual reloading, by a single function of the trigger." This definition includes any frame, receiver, or parts to make a machine gun.

Definition of "can be readily restored to shoot", in particular, is one upon which reasonable minds can differ.

  • Somewhat belabored answer that comes down to "he can if the Congress gives him the authority and the definitions are loose enough." So essentially the same as the other anwer, which I also don't like too much because of the "No" upfront, despite the details. On the other hand, the only class 3 debate is around gimmicky stuff like puttina rubber band on the trigger. Which as far as I know is not a device used with any regularity by mass shooters and the like, so a rather academic question. Commented Jun 13, 2022 at 23:57
  • If POTUS were to reclassify semi-auto firearms as class 3 somehow, based on the superloose interpretation you (seem to) suggest, you can bet your house the current SCOTUS would strike that down in a jiffie. So the "yes" conclusion is probably even more wrong than the "no" one, on any reclassification of import, under the current legislation. Commented Jun 14, 2022 at 0:05
  • @Fizz I'm not suggesting a blanket reclassification or semi-automatic firearms with the current statute, although there might be some particular semi-automatic firearms based upon fully automatic designs which would be trivial to convert to automatic and thus come within the definition. But the question asked and the one I am answering is not whether there could be a blanket reclassification of semi-automatic weapons.

  • @Fizz None in particular. There are thousands of guns classified under the NFA. I've heard arguments that it is possible to reclassify some based upon easy conversion. But, I don't claim to have exhaustive knowledge of every model of gun out there.

Just as a point of information, the last category of firearms that was (effectively) banned by reclassification were those using "bump stocks", following the (2017) Las Vegas massacre.

But even for these it's somewhat dicey whether the ban will ultimately hold in courts; in one appeals court (Sixth Circuit) it was upheld by 8-8 (deadlock equals upheld there). Insofar SCOTUS has been "dancing around" such cases, becoming famous for rescheduling them numerous times.

The case joins one already awaiting a decision on US Supreme Court review, Aposhian v. Garland. The high court has rescheduled its consideration of whether to take bump stock proponent W. Clark Aposhian’s case numerous times.

(One can probably appreciate the bind that a court with three Trump appointed judges would have in overturning a Trump-issued gun ban, even moreso given the apparently crushing public opinion majority in favor of the ban.)

So the answer to whether some guns could be banned (past tense) by recategorization, is obviously yes.

However, it is difficult to see how much further the executive could push the machine-gun reclassification angle (to other categories) given the risks of having more "stretchy" recategorizations overturned in courts.

As the question appears to have evolved into something about taking a guess which short guns might bannable via reclassification... there's also some level of court precedent on that:

As a result of the Supreme Court decision in United States v. Thompson/Center Arms Company, 504 U.S. 505 (1992), it is not illegal to possess a "kit" allowing a handgun to be fitted with a buttstock and with barrels both under and over the 16 inch minimum for a rifle, so long as the firearm is only assembled into legal (handgun with no buttstock, rifle with buttstock and 16 inch or longer barrel) configurations. Assembling the firearm into an NFA-regulated configuration (rifle with buttstock but barrel shorter than 16 inches) would be a violation of the National Firearms Act.

So, I'd say a lot of the fringes of what's reclassifiable have been... explored.

3rd time's the charm? A comment has explained that

But to address your "certain firearms" request, the opinion piece was referring to "high velocity, massive trauma inducing weapons" The author was not suggesting "banning" weapons, rather that certain weapons (by way of classification) might have additional regulation requirements.

If you look the present classification, there's no basis for classifying by bullet velocity. As for the level of trauma... that might be debatable given that the category of "destructive device " exists, but in the fine print it's rather difficult to assign rifles to it, other than those over .50 inches in bore.

There might be leeway for 12-gauge shotguns (0.729" caliber) and 20-gauge shotguns (0.615 in) to be banned this way because it seems the exception for those does fall under the executive's decision/discretion.

the barrel or barrels of which have a bore of more than one-half inch in diameter (.50 inches or 12.7 mm) except a shotgun or shotgun shell which the Secretary finds is generally recognized as particularly suitable for sporting purposes.

I suspect that unless there's some kind of shotgun-based massacre, that won't happen, given that they are not exactly the near-military style weapon derivatives that was e.g. the focus of the assault weapons ban etc. OTOH looking closely at the latter, some semi-automatic shotguns were banned, specifically those with detachable magazines (and some based on features that seem less relevant to me). So I'm guessing there is leeway in the law for the executive to ban/reclassify those.

  • Even in the bump-stock case, the issue is not whether the President can reclassify a firearm. It is whether this particular reclassification was justified or proper, not a broad challenge to the authority of a President to reconsider a regulatory decision made in a prior administration under the NFA.
