10th Circuit Revives Colorado Ghost Gun Fight—Two Fronts Open

The Tenth Circuit reversed a lower court's denial of injunctive relief against Colorado's possession ban on unserialized firearms. At the same time, the panel confirmed that the ATF's serialization rule is still on the table for legal challenge—even after the Supreme Court declined to strike it down earlier.

Two fronts. Reopened. At once.

**That's not a minor procedural footnote. That's a direct threat to the entire anti-gun legislative architecture Colorado has been building for years.**

Let's be clear about what's actually being banned here. These aren't untraceable weapons of war cooked up in a back alley. They're homemade, unserialized firearms—legal under federal law, and part of American gun culture stretching back more than two centuries. Colorado's Democrat-controlled legislature, led by Governor Jared Polis with a supermajority at his back, decided law-abiding gunsmiths and home builders were the threat. They were wrong. And now a federal appellate court is making them prove otherwise.

Under the post-*Bruen* framework, the burden sits squarely on the government. Colorado must show that its blanket possession ban is rooted in the nation's historical tradition of firearm regulation. The historical record on banning homemade, unserialized guns? It doesn't exist. Because the ban itself is a modern invention dressed up as public safety.

The district court now gets the case back on remand with fresh instructions: take another hard look. If the lower court grants injunctive relief this time, Colorado's unserialized firearm ban could be blocked while the full case plays out. That's a real, tangible win for Colorado gun owners—not in five years, now.

**This is exactly how the Second Amendment gets defended: inch by inch, ruling by ruling, forcing anti-gun states to stand in front of a judge and explain themselves.**

Polis and his allies bet that stacking restriction on top of restriction would eventually normalize the pile. The Tenth Circuit just kicked out a load-bearing beam.

Watch the remand proceedings closely. Watch whether the district court grants that injunction. And watch what happens to the ATF serialization challenge now that the appellate court has confirmed it isn't dead—because that fight has implications that reach far beyond Colorado's borders.

Support the organizations litigating this case. If you're in Colorado, know your rights and know this case by name. The momentum is real, the wins are stacking up, and the other side is running out of easy ground to hold.

**The Tenth Circuit just opened two fronts at once. Don't look away.**
