10th Circuit Revives Colorado Ghost Gun Fight — State Ban Now Exposed

The Tenth Circuit drew a bright, unambiguous line: Colorado's ban on possessing unserialized firearms and the ATF's federal ghost gun rule are two separate legal animals. Killing one does not kill the other. And right now, both are still alive.

The appeals court reversed the district court's denial of injunctive relief on Colorado's unserialized firearms possession ban — sending the case back down with a direct order: look at this again, and this time get it right.

**That's not a stumble. That's a body blow.**

Colorado Democrats built this law on a calculated bet — that the ATF rule would give them political air cover and legal armor. They thought the Supreme Court's 2025 ruling upholding the ATF's ghost gun rule would bury these challenges for good.

It didn't. Not even close.

The Second Amendment Foundation and its allied plaintiffs refused to treat SCOTUS's ATF decision as a defeat. They stayed disciplined — jurisdiction by jurisdiction, provision by provision — and today that strategy cracked Colorado's anti-gun framework at the foundation.

**This is what the long game looks like. And it's working.**

If the district court grants the injunction on remand, Colorado gun owners could see immediate, real-world relief from one of the state's most aggressive crackdowns on unserialized firearms — while the full litigation plays out.

Watch this case. The lower court's next move will tell you everything about whether Colorado's legislature overplayed its hand — or whether they'll be allowed to finish what they started.

The organizations carrying this fight are winning. That matters. And so does what happens next.
