SCOTUS Could Nuke Colorado's Ghost Gun Law—Any Day Now

The 10th Circuit ordered a lower court to take a fresh look at the challenge to Colorado's ghost gun serialization law. Sounds like a win for the state. It isn't. Not even close.

The U.S. Supreme Court is weeks—possibly days—away from ruling on whether the ATF ever had the legal authority to classify gun parts kits as "firearms" under federal law. Colorado's serialization mandate was modeled directly on that same embattled ATF rule. If SCOTUS guts the federal rule, Colorado's law loses its foundation. The whole thing could come down like a condemned building.

**Two layers of government overreach stacked on top of each other—and the court used Layer Two as an excuse not to touch Layer One.**

That is the part that should stop you cold. Judge Gordon Gallagher's majority reasoned that blocking Colorado's law wouldn't matter anyway, because the federal ATF rule would still require serialization. So they punted. They sent it back to district court rather than striking it down outright—using the existence of federal overreach to justify leaving state overreach untouched.

Judge Paul Kelly pushed back on that logic. Good. Because the majority's reasoning doesn't protect gun owners—it delays their relief while Colorado's anti-gun legislature keeps an unconstitutional law on the books and law-abiding builders remain in legal jeopardy right now, today.

Here is what Colorado's law actually does: it criminalizes the act of building your own firearm without a government-issued serial number stamped on the frame or receiver. That's it. That is the offense. Not selling a weapon illegally. Not carrying without a permit. *Building your own gun in your own garage without asking permission first.*

**The Founders built their own guns. Your grandfather built his own guns. The Second Amendment has exactly zero words about ATF permission slips.**

Colorado Democrats pushed this through under the same "close the ghost gun loophole" playbook that Bloomberg-backed groups have run in every blue state on the map. The script never changes because the goal never changes. But here is the truth they will not say out loud: criminals do not serialize their firearms and never will. This law touches exactly one category of person—the law-abiding citizen exercising a constitutional right in his own home.

There is no loophole. There is a right.

Now the clock is running. When the Supreme Court's ATF ruling lands—and it is coming—Acting AG Todd Blanche's DOJ needs to move fast. If SCOTUS strips the ATF's authority to regulate parts kits, the administration must use that ruling aggressively to challenge every state copycat law built on that same federal foundation. Colorado's law is first in line.

The fight didn't end with the 10th Circuit's ruling. It just relocated to district court—temporarily. The real verdict is being written right now in One First Street, Washington, D.C.

**Watch the Supreme Court.** When that ruling drops, the legal ground under Colorado's ghost gun ban could crack wide open overnight. If you are a Colorado gun owner or builder, find the plaintiffs in this case, make noise with your state legislators, and be ready to move. The window may open fast—and close just as fast.

This is the story that matters this month. Don't look away.
