10th Circuit Revives Challenge to Colorado's Ghost Gun Crackdown

The federal appeals court has ruled that Second Amendment advocates have standing to challenge Colorado's ban on possessing unserialized firearms—and that the district court was dead wrong to deny them a preliminary injunction. The case goes back down for another look, and the state's enforcement of that possession ban is now legally exposed.

Here's the move Colorado's attorneys tried to run: the ATF's federal "ghost gun" rule survived at the Supreme Court, so why should a state-level challenge live? The Tenth Circuit wasn't buying it. The federal rule and Colorado's state ban are two separate legal animals. One loss at the top doesn't kill the whole fight—and the appeals court refused to let it.

**That's not a technicality. That's a lifeline.**

Colorado's law doesn't just restrict how you buy or build a firearm. It criminalizes *possession*—full stop—of any unserialized gun. That sweeps in legally built, homemade firearms that Americans have been constructing for personal use since before this country had a flag. Home gunsmithing isn't a loophole. It's a tradition older than the Second Amendment itself.

Colorado Democrats didn't write this law to stop criminals. Criminals don't serialize anything—never have, never will. They wrote it to turn ordinary, law-abiding gun owners into felons for doing something generations of Americans did in their garages without a second thought.

Post-*Bruen*, that kind of overreach has a target on its back. Courts are being forced—slowly, grudgingly, but forced—to apply the Second Amendment as written, not as progressive state legislatures wish it read. Anti-gun legislatures are losing ground they assumed was permanently theirs.

**The war isn't won. But the Tenth Circuit just handed the good guys a weapon for the next round.**

The case returns to the district court, where plaintiffs—backed by Rocky Mountain Gun Owners, the Firearms Policy Coalition, and the Second Amendment Foundation—will push hard for the injunction that was wrongly denied. These organizations do the grinding, expensive, unglamorous courtroom work that keeps your rights alive. That work doesn't happen without funding.

Watch this case. Colorado cracked the door when it passed this law. The Tenth Circuit just told the plaintiffs: *now kick it off the hinges.*
