Assault weapon, ghost gun, arsenal, how news vocabulary does the arguing

I want you to try an experiment the next time a gun story comes on the screen. Turn the sound off, read the chyron and count the adjectives. By the time the anchor says a word, the story has already been decided. A man was found with an "arsenal." The weapon was a "military-style assault weapon." It had been assembled from a "ghost gun" kit. Nobody has yet told you what happened, and you already know who the villain is and what law should be passed.

That is the trick, and it is a good one. When a word carries its conclusion with it, the argument is won before it starts, and the audience never notices that it was asked to agree to something. Let me give you seven of these words, in the order they most often appear, and for each one give the legal or technical meaning, the way coverage uses it and a neutral alternative. I am not asking you to stop caring about violence. I am asking you to insist that the case for a law be made in plain words, where it can be tested.

The rule of the exercise

A fairness note first. Words matter on both sides of this debate, and the gun-rights side has its own loaded vocabulary: "gun grabbers," "black rifle," the industry's own marketing phrase "modern sporting rifle." Some of those terms are partisan and some are marketing, and a careful writer should avoid them too. The test I apply is the same for everyone. Does the word describe the object, or does it argue for a policy about the object? If it argues, find a plainer one.

Word one: "assault weapon"

The legal meaning. There is no single, fixed definition. The term is a legislative category, and it means whatever the statute that uses it says. The best-known federal definition was in the Public Safety and Recreational Firearms Use Protection Act, part of the Violent Crime Control and Law Enforcement Act of 1994, which for ten years banned new manufacture and transfer of certain semi-automatic firearms. The ban expired on September 13, 2004. Under it, a semi-automatic rifle that accepted a detachable magazine was an "assault weapon" if it had two or more listed features, such as a folding or telescoping stock, a pistol grip that protrudes conspicuously beneath the action, a bayonet mount, a flash suppressor or threaded barrel, or a grenade launcher mount. Pistols and shotguns had their own feature lists.

How coverage uses it. As if it described a class of machine with an obvious military function. The reader hears "assault" and "weapon" and pictures a machine built for attack.

What the term hides. The features on the list were mostly cosmetic or ergonomic. A rifle without a bayonet mount and with a fixed stock fired the same ammunition at the same rate as the identical rifle with them. Under the 1994 law, a rifle with enough listed features was covered and the otherwise identical rifle with fewer was not. State laws have used differing lists, so a rifle can be an "assault weapon" in one state and an ordinary rifle in the next.

A neutral alternative. "Semi-automatic rifle," followed by whatever feature is actually at issue. If the point is the magazine, say magazine. If the point is a cosmetic feature, name it.

Word two: "assault rifle" and the machine-gun confusion

The technical meaning. In military usage, an "assault rifle" is a rifle that can fire in a selective mode, either semi-automatic or fully automatic, using an intermediate-power cartridge and a detachable magazine. The defining feature is selective fire: with the selector in the automatic position, the weapon fires continuously while the trigger is held.

The legal reality. Fully automatic weapons, which the law calls machine guns, have been regulated since the National Firearms Act of 1934, which imposes registration and a tax. Since the Firearm Owners Protection Act of 1986, which added section 922(o) to the Gun Control Act, civilians may not possess machine guns made after May 19, 1986, with limited exceptions, and the older ones that remain in civilian hands are registered and expensive. The AR-15, the rifle most often meant when coverage says "assault weapon," fires one round per trigger pull. The "AR" stands for ArmaLite, the company that designed the original, and not for "assault rifle."

How coverage uses it. The two terms are used interchangeably, so that readers conclude that civilians can buy fully automatic military rifles at will. They cannot.

A neutral alternative. "Semi-automatic rifle" for the commonly sold rifle, and "machine gun" for a weapon that fires automatically, which has its own distinct legal regime.

Word three: "ghost gun"

The legal meaning. "Ghost gun" has no legal definition either. It was popularized as a label for a firearm without a serial number, usually one that a person assembles from parts or from an unfinished frame or receiver, sometimes called an "80 percent" frame or receiver. The legally relevant term is frame or receiver. Under the Gun Control Act, the frame or receiver is the part of a firearm that the law treats as "the firearm" for purposes of serialization, record-keeping and background checks. A licensed manufacturer must mark it with a serial number, and a licensed dealer must run a check when it is sold.

In April 2022 the Bureau of Alcohol, Tobacco, Firearms and Explosives issued a final rule, effective in August of that year, that redefined "frame or receiver" and clarified that certain kits and partially complete frames that can readily be completed to function would be treated as firearms. The Supreme Court considered the rule in Bondi v. VanDerStok, decided in March 2025, and held, by a vote of seven to two, that the rule was not facially inconsistent with the Gun Control Act. The decision left open challenges to specific applications.

Two facts the label hides. First, making a firearm for personal use has long been lawful under federal law, for a person who may lawfully possess one, and homemade guns are not a new invention: many Americans in the nineteenth century built their own. Second, a homemade gun is no more invisible than any other object: it is simply unserialized. The word "ghost" implies something invisible and sinister, when it describes an object with a particular legal and record-keeping status.

A neutral alternative. "Privately made firearm," which is the term the ATF itself uses, or "unserialized firearm." Those are accurate and imply no conclusion.

Word four: "arsenal"

The meaning. An arsenal is a building where a government makes and stores weapons. Nothing in law or in ordinary usage sets a number of guns at which a collection becomes one.

How coverage uses it. A story reports that police found "an arsenal" in a suspect's home, and the reader pictures a bunker. The number of guns is rarely given. When it is, it often turns out to be an amount that a hunter, a collector or a competitive shooter might own, since Americans who own firearms often own several, for the same reason a person owns more than one pair of shoes: different tasks call for different tools. A rifle for deer, a shotgun for birds, a pistol for the home, a small-bore rifle for a child learning.

Why the word is a problem. It is a verdict wearing the costume of a description. It tells the reader that the quantity is itself menacing, and it makes no distinction between a man with eight lawfully purchased guns and a man with eight stolen guns and a plan.

A neutral alternative. The actual number and types, stated plainly: "police recovered nine firearms, including three rifles, four handguns and two shotguns." The facts are more informative than the adjective.

Word five: "high-capacity magazine"

The technical meaning. A magazine is the device that holds cartridges for feeding into a firearm. Its capacity is the number of rounds it holds. There is no natural line between "standard" and "high" capacity: the capacity that a firearm is designed to use is its standard. Many AR-15 rifles are commonly sold with magazines of thirty rounds, and many full-size pistols are sold with magazines of fifteen or more rounds. The 1994 federal law restricted new magazines holding more than ten rounds, and some states limit magazines to ten or fifteen.

How coverage uses it. "High-capacity" implies that the magazine is abnormally large, an extra, a deluxe feature, when for many popular firearms it is a common factory size and the ten-round version is the reduced one.

What else the word hides. People often say "clip" for "magazine," and the two are not the same: a clip is a device that holds cartridges together for loading into a magazine or a chamber, as in the old military rifles, and a magazine feeds them. The error is harmless in conversation but a sign that the speaker may not be sure what is being debated.

A neutral alternative. "Standard-capacity magazine" if the speaker is describing the factory standard, or simply "a 30-round magazine" if the number is the issue. The number, again, is more informative than the adjective, and it lets the reader decide whether ten, fifteen or thirty is the right line.

Word six: "military-style"

The meaning. It means that the firearm resembles a military one. It does not mean that the firearm is used by any military. The most common sporting rifle in America, the AR-15, looks like the rifle that the army has issued, the M16, and differs in the most important way: the military rifle has a selector for automatic or burst fire, and the civilian rifle does not.

How coverage uses it. As a short way to connect a civilian rifle with the battlefield.

An argument about the word. Appearance is the very ground on which the 1994 ban was built, and the cosmetics on the list were the military look. It would be fair to ask whether a law should regulate the look or the function. If a rifle with a wooden stock and a rifle with a black polymer stock fire the same cartridge the same way, a law that treats the second more severely is regulating style.

A neutral alternative. Describe the function: "a semi-automatic rifle chambered in .223 or 5.56 millimeter," whatever the facts are.

Word seven: "weapon of war"

The meaning. This phrase has real legal history, which makes it the subtlest of the seven. In District of Columbia v. Heller (2008), the Court noted that the amendment protects arms "in common use at the time" and does not protect "dangerous and unusual weapons," and suggested in dicta that weapons that are most useful in military service, such as the M16 rifle, may be banned. Some lower courts and some advocates take that passage to mean that the civilian rifle, which resembles a military one, can be banned. Others point out that the passage describes weapons "most useful in military service," and that the most widely owned rifle in the country is, by definition, in common use, not unusual.

How coverage uses it. As an unqualified phrase ("weapons of war on our streets") that treats the legal question as already answered in favor of a ban.

Why the claim is contested. First, the term proves too much. Nearly every firearm design has military origins, including the bolt-action hunting rifle that descends from military rifles, and the revolver. Second, the test in Heller is common use for lawful purposes, and the best evidence of common use is that millions of Americans own the firearm in question and use it for sport and self-defense. Third, the framers' idea of the militia was the people themselves, armed with the weapons of the day. George Mason and the well regulated militia composed of the body of the people covers how that worked.

A neutral alternative. "Rifle" or "semi-automatic rifle," and if the point is a legal one, say it as a legal argument: "whether the AR-15 is in common use for lawful purposes."

Steelmanning the other side

A critic of this essay would say: words that make people uneasy are not necessarily wrong. A person who is shocked at the sight of a rifle designed for rapid firing may have a point, and a news organization that avoids "assault weapon" may simply be adopting the vocabulary of the gun lobby.

There is something to that. "Assault weapon" is not, in itself, a lie: it is a legislative category that many states use, and a story about a state law should use the state law's term. Coverage that avoids all adjectives would be unreadable. And some of the technical distinctions I have drawn can feel like quibbling to a person who has lost a loved one.

My answer is that the words should be used where they are the law's own terms and explained when they are not. Where a story quotes a statute, quote it. Where the reporter is describing a particular firearm, describe it. The test is whether the reader can tell what he is being asked to believe. A person who wants a ban on a category of firearm is entitled to argue for it, and the argument is stronger, not weaker, if he can say what the category is and why it should be treated differently, in words that do not do the work for him.

A seven-word cheat sheet

1. Assault weapon: a statutory label, defined by a list of features; say "semi-automatic rifle" and name the feature.
2. Assault rifle: a selective-fire military rifle; civilians may not buy new ones, and most coverage means the semi-automatic civilian version.
3. Ghost gun: a slogan for a privately made, unserialized firearm; say that.
4. Arsenal: a building, not a number; give the number and types.
5. High-capacity: relative to what? Give the number.
6. Military-style: a look, not a function; describe the function.
7. Weapon of war: a legal argument; state it as one.

The Founders understood the importance of words, which is why they wrote the Bill of Rights in plain ones. Compare the clarity of "shall not be infringed" with a phrase that must be defined by a seven-page statute.

The site's glossary gives plain definitions of other terms.

The case in brief

1. A word that carries its conclusion with it wins an argument without making one, and readers should learn to notice it.
2. "Assault weapon" is a statutory category built on a feature list, "assault rifle" is a selective-fire military term, and the two are routinely confused.
3. "Ghost gun," "arsenal," "high-capacity," "military-style" and "weapon of war" each describe a number, a function or a legal question more precisely when stated plainly.
4. Both sides of the debate have loaded terms, and the right test is whether the word describes the object or argues about it.
5. A policy that is worth enacting can be defended in plain words, and a policy that needs a loaded vocabulary should make us ask why.

What you can do: the next time you read a gun story, circle each adjective, replace it with a number or a plain description, and notice how much of the story is left.
