Supreme Court Takes AR-15 Bans

The Supreme Court agreed July 1 to decide whether the Second Amendment protects the right to own AR-15s and similar semiautomatic rifles — the first time the Court has ever taken up a direct challenge to categorical firearms bans.

State of play: Two cases are consolidated for review — one challenging Connecticut's assault weapons law, the other targeting Cook County, Illinois's ordinance. Oral arguments begin in October.

Catch up quick:

• Connecticut banned "assault weapons" in 1993, tightened restrictions after Sandy Hook in 2012
• Cook County's ordinance bans AR-15s, AK-47s, and magazines over 10 rounds — violations carry up to six months in prison and a $5,000 minimum fine
• Both the Second and Seventh Circuits upheld the bans; gun owners appealed to SCOTUS
• The Court had declined AR-15 ban challenges multiple times after Bruen in 2022 — until now

The legal question: Everything turns on Bruen's test — the 2022 ruling that said gun restrictions must be rooted in America's historical tradition of arms regulation. The lower courts found those bans consistent with that tradition. The plaintiffs argue the AR-15 is "the most popular rifle in the country," owned by tens of millions of Americans, and no historical analogue justifies banning it outright.

"The three-judge panel called AR-type rifles 'dangerous and unusual' and 'particularly suited for criminal violence.'" — Second Circuit Court of Appeals

Between the lines: The Court sitting on these challenges after Bruen looked like strategic patience — waiting for the right case on the right circuit split. Now they have it. That shift matters. A Court that twice passed on Illinois AR-15 bans doesn't suddenly grant cert because of a slow docket.

By the numbers:

• 14 states plus D.C. have laws restricting semiautomatic weapons that would be affected by the ruling
• ~20 million AR-15-pattern rifles are estimated to be in civilian hands in the U.S.
• Two circuits — the Second and Seventh — have now upheld categorical bans under Bruen

What gun owners should know: A ruling for the plaintiffs wouldn't just kill Connecticut's and Cook County's laws — it would functionally invalidate every state-level assault weapons ban. A ruling against would hand governments a template for categorical bans that survives constitutional scrutiny. There's no middle ground here that leaves the landscape unchanged.

What to watch: How the Court frames "dangerous and unusual" is the linchpin. If they reject that standard as applied to widely-owned semiautomatic rifles, the legal foundation under every existing assault weapons ban cracks. Watch the oral argument questions in October — the justices' skepticism or sympathy toward the historical tradition analysis will telegraph the outcome before the opinion drops.
