H.R. 3115: Assault Weapons Ban of 2025

H.R. 3115 takes a two-pronged approach. First, it defines "semiautomatic assault weapon" by features: any semiautomatic rifle with a detachable magazine plus one military-style attachment — pistol grip, folding stock, barrel shroud, threaded barrel, forward grip, or grenade launcher. The same framework applies to certain pistols, shotguns, belt-fed semiautomatics, and any part or accessory designed to increase rate of fire without converting the gun into a machine gun.

Second, the bill names specific models. Over 200 firearms are listed individually — every AK and AR variant, the Sig Sauer MCX, Beretta CX4 Storm, Kel-Tec Sub-2000, and dozens more, plus "copies, duplicates, variants, or altered facsimiles." That language is designed to stop manufacturers from skirting the ban with cosmetic redesigns.

Magazines, belts, drums, and feed strips holding more than 15 rounds become illegal to sell, manufacture, or import. Existing large-capacity magazines can be kept but cannot be transferred.

Owners of covered weapons who possessed them lawfully before enactment are grandfathered — but with strings attached. They must store the weapon with a secure locking device if anyone prohibited from possessing firearms could access it. Any private sale or transfer must go through a licensed dealer for a background check, starting 90 days after the law takes effect. No more parking-lot handoffs.

The bill includes a severability clause — a signal that sponsors expect legal challenges and want the rest of the law to survive if any single provision is struck down.

Finally, H.R. 3115 opens federal Byrne Grant funding for state and local government buyback programs, giving jurisdictions a revenue source to compensate people who voluntarily surrender covered weapons or magazines.
