10th Circuit Slaps Colorado's Ghost Gun Ban Back to Court

The Tenth Circuit reversed a lower court's denial of injunctive relief against Colorado's unserialized firearms possession ban, sending the fight back to district court for the full constitutional reckoning the state desperately wanted to avoid.

Here's the cut that matters: the Supreme Court upholding the ATF's federal ghost gun rule does *not* get Colorado off the hook. State-level bans live or die on their own merits under Bruen and Rahimi—and the Tenth Circuit just confirmed that fight is wide open.

**Colorado wanted a free pass. It didn't get one.**

The appellate court also confirmed plaintiffs have independent standing to challenge the ATF rule separately—meaning there are two live legal battles here, not one. The state just lost its shortcut on the more consequential of the two.

This isn't abstract procedure. Colorado gun owners who built legal, unserialized firearms before federal serialization requirements applied to their circumstances have faced criminal prosecution under this law. An injunction, if granted on remand, halts that enforcement while the constitutional merits play out in full.

Governor Jared Polis and Colorado's gun-control legislature have spent years stacking state restrictions on top of federal ones, banking on one simple bet: that litigation costs and delays would grind challengers into dust. This ruling tears a hole in that strategy.

**Courts are still in this fight. So are we.**

Watch the district court remand closely. The Tenth Circuit signaled the lower court must take the injunction request seriously—that's the opening litigators needed, and it's an opening that could freeze Colorado's enforcement in its tracks.

This case is far from over, and that's exactly the point. Colorado's unserialized firearm ban is not settled law. It's headed back into the fire—and the state knows it.
