A three-judge panel of the First Circuit just handed Massachusetts another win in its long-running war on the AR-15 platform, ruling that the state’s “assault weapons” ban survives Second Amendment scrutiny. The decision leans heavily on the notion that these firearms are not “in common use” for lawful purposes—an argument that conveniently ignores the fact that millions of law-abiding Americans already own them for home defense, competition, and collecting. By treating a popular, modern sporting rifle as somehow outside the Amendment’s protection, the court effectively green-lights future restrictions on any semi-automatic firearm that looks “military” enough to offend legislators.

For the 2A community this ruling is a flashing warning light. It shows how easily post-Bruen courts can still smuggle interest-balancing back into the analysis by redefining what counts as an “Arms” in the first place. If a rifle owned by roughly twenty million citizens can be declared “unusual,” then the same logic could be applied to standard-capacity magazines, pistol braces, or even optics—anything a state decides to stigmatize. The decision also highlights the geographic lottery that now governs constitutional rights: what is protected in Texas or Florida can be criminalized in Massachusetts or California with little more than a three-judge panel’s say-so.

The practical takeaway is that litigation alone will not restore these rights. Massachusetts gun owners now face the familiar choice between costly appeals, legislative pushback, or simply complying with a ban that treats an entire class of commonly owned firearms as contraband. Until the Supreme Court squarely addresses what “in common use” actually means—and whether states can ban the most popular rifle in America—the patchwork of restrictions will keep expanding, one circuit opinion at a time.
