10th Circuit to Colorado: Your Ghost Gun Ban Isn't Safe

The Tenth Circuit reversed a lower court's denial of injunctive relief against Colorado's ban on possessing unserialized firearms. Translation: the law cannot quietly roll into full enforcement unchallenged. Plaintiffs get a real hearing. **The fight is back on.**

Here's the move anti-gun politicians in Denver tried to pull. After the Supreme Court upheld the ATF's federal 'ghost gun' frame rule in *Garland v. VanDerStok*, Colorado's lawyers essentially argued the constitutional debate was over—closed, locked, done. The Tenth Circuit looked at that argument and threw it out.

The court was explicit: the federal regulatory question and Colorado's separate state-level possession ban are two different animals. A win for the ATF in Washington does not hand Colorado a free pass to criminalize firearms at home. **Federal regulatory approval is not a Second Amendment hall pass.**

And Colorado's law is not some minor restriction. It makes simple possession of any unserialized firearm a felony—no criminal intent required, no trafficking, no violent crime attached. Just owning a legally home-built gun that Americans have produced for personal use for over a century puts you in handcuffs under this scheme.

The district court originally waved the challenge away. The Tenth Circuit disagreed, loudly. The injunction question now returns to the district court for a full merits hearing—exactly the arena Second Amendment advocates need.

**This ruling is a blueprint, and other states should feel it.**

California, New Jersey, Illinois—every state capitol drafting a copycat possession ban should read this opinion carefully. Federal appellate courts are refusing to accept the argument that one Biden-era ATF rule settled every constitutional question about unserialized firearms forever. That shortcut is closed.

On remand, plaintiffs can now argue that enforcing this felony possession ban while litigation continues causes irreparable harm to gun owners' Second Amendment rights—a powerful threshold argument that the lower court never properly weighed.

Colorado spent years building one of the most aggressive unserialized-firearm regimes in the country. The Tenth Circuit just handed the bill back and said: *prove it's constitutional first.*

If you legally own a home-built firearm in Colorado, consult a Second Amendment attorney now. And keep your eyes on this case—because the merits hearing coming out of this ruling could produce an opinion that reshapes the unserialized-firearm landscape coast to coast. **This isn't over. It's just getting started.**
