10th Circuit Cracks CO Ghost Gun Law—SCOTUS Could Finish It

A three-judge 10th Circuit panel has ordered a federal district court to take a second crack at the constitutional challenge to Colorado's law demanding serial numbers on privately made firearms. The lower court didn't get it right the first time. Now it has to try again—under rules that are far less friendly to the government.

Judges Allison Eid, Joel Carson, and Paul Kelly sent the case back with a clear signal: apply a more demanding constitutional framework. That almost certainly means the rigorous historical analysis the Supreme Court mandated in *Bruen*. Colorado's bureaucrats built this law on soft ground. The remand just yanked the rug.

**But here's the move gun owners can't afford to miss.**

Judge Gordon Gallagher flagged it himself: even if Colorado's state law gets struck down, the Biden-era ATF rule forcing serial numbers on gun components could survive independently. One court win doesn't end the fight. This is a two-front legal war—one in state courts, one against a federal agency that literally wrote its own authority into existence with a 2022 rulemaking.

And that federal authority is exactly what the Supreme Court is about to examine.

SCOTUS is positioned to rule on whether ATF ever had the legal power to regulate gun components as firearms in the first place. If the Court's conservative majority decides ATF overstepped—and they have every reason to—it doesn't just wound Colorado's law. It guts the federal backbone that a dozen anti-gun state legislatures have been leaning on.

Colorado's serial-number mandate is not a local quirk. It is one piece of a coordinated national campaign to criminalize the private manufacture of firearms—a tradition as old as the Republic itself. They call it "traceability." **Call it what it is: the first step toward a registry of every gun in your home.**

The Biden ATF rammed its component rule through in 2022 precisely to give state-level efforts like Colorado's a federal backstop. Strip ATF of that authority and the state lawmakers lose their cover—and their lawyers know it.

The 10th Circuit remand buys time. It forces the lower court to do the work properly. But the real detonation is coming from Washington.

Watch the SCOTUS ATF component case. A ruling that ATF overstepped blows a hole straight through Colorado's law—and sends shockwaves through every state that copied the playbook. The 2A legal machine is grinding in the right direction. **Don't look away now.**
