DOJ Targets D.C. AR-15 & Suppressor Bans as Second Amendment Civil Rights Violations
The Trump Justice Department just sharpened its attack on Washington, D.C.’s gun-control regime, and this time the target is bigger than a single bad law.
In a First Amended Complaint filed May 14, 2026, the United States argues that the District of Columbia, its Metropolitan Police Department, and Acting Police Chief Jeffrey Carroll are violating the Second Amendment by enforcing local laws that ban AR-15-style rifles and suppressors. The lawsuit, filed in the U.S. District Court for the District of Columbia, asks a federal judge to declare those bans unconstitutional and block D.C. from enforcing them.
This is not another private citizen begging the courts to recognize what the Constitution already says. This is the United States government suing the District of Columbia and saying, in plain terms, that D.C.’s gun laws deprive Americans of their civil rights.
That is a major shift.
For decades, anti-gun politicians have treated the Second Amendment like a second-class right. They have banned commonly owned rifles, criminalized ordinary gun parts and accessories, buried lawful owners in registration schemes, and then acted shocked when Americans objected. D.C. has long been one of the worst offenders. This amended complaint puts that record directly in the federal government’s crosshairs.
The filing opens with the point gun owners have been making since Heller: the Second Amendment protects a pre-existing right, not a privilege handed out by politicians. DOJ cites Heller, McDonald, and Bruen to argue that law-abiding Americans have the right to possess and use arms that are in common use for lawful purposes.
That is where D.C.’s AR-15 ban runs into trouble. D.C. does not simply say, “AR-15s are banned,” at least not in the clean way some states do. Instead, the District uses its registration scheme to get the same result. Under D.C. law, a person may not possess a firearm unless it is registered with the police. Then D.C. refuses to issue registration certificates for so-called “assault weapons,” a category that includes AR-15-platform rifles.
The result is the same: possess an AR-15 in D.C., and you are treated like a criminal.
The complaint correctly attacks the loaded phrase “assault weapon” for what it is: political language, not a serious firearms term. The AR-15 is not exotic or rare. It is not some strange military artifact sitting outside the American firearms tradition. It is the most popular rifle platform in the country.
DOJ’s amended complaint leans hard into that reality. The complaint cites estimates that Americans own 20 to 30 million AR-15s. It also points to Justice Kagan’s recent observation that the AR-15 is “the most popular rifle in the country.” It then cites Justice Kavanaugh’s statement in Snope v. Brown, where he noted that because millions of Americans own AR-15s and most states allow them, challengers have a strong argument that AR-15s are protected under Heller’s common-use test.
If the Second Amendment protects arms in common use for lawful purposes, then D.C. cannot ban the most popular rifle in America just because anti-gun politicians dislike it. The Constitution does not allow local officials to veto ordinary rifle ownership with scary language and a registration trap.
The complaint also lays out why Americans own AR-style rifles. DOJ cites surveys showing they are used for recreational target shooting, home defense, hunting, defense outside the home, and competition. In other words, the exact kind of lawful purposes the Second Amendment protects.
The filing also undercuts the usual gun-control narrative that AR-15s are uniquely tied to crime. DOJ notes that FBI homicide data from 2019 showed only 364 homicides with rifles of any kind, compared with 6,368 with handguns, 1,476 with knives or cutting instruments, 600 with hands, feet, or other personal weapons, and 397 with blunt objects.
Anti-gun politicians do not want Americans to see those numbers. The numbers wreck the narrative.
