DOJ Says Federal Handgun Sales Ban for 18–20-Year-Olds Is Unconstitutional
A major change in the federal government’s position on firearm law could affect how adults ages 18 to 20 obtain handguns—but there are still important details to understand before assuming the rules have completely changed.
On September 17, 2026, the Justice Department’s Office of Legal Counsel (OLC) issued an opinion concluding that federal laws restricting federally licensed firearms dealers from selling handguns to otherwise eligible adults ages 18 to 20 cannot constitutionally be enforced under the Second Amendment.
The decision addresses a restriction that has been in federal law for decades. Under the existing statutes, federally licensed dealers have been prohibited from selling handguns and handgun ammunition to customers under 21.
The DOJ's new position does not, however, amount to Congress repealing those laws.

What DOJ Actually Decided
The OLC opinion focused on federal provisions that prohibit federally licensed dealers from selling handguns to 18-, 19-, and 20-year-olds.
According to the opinion, those adults fall within the Second Amendment's protection, and handguns constitute protected "arms." OLC also concluded that the government cannot avoid Second Amendment scrutiny simply by regulating the seller rather than directly prohibiting the buyer from possessing a firearm.
That distinction matters.
If someone is legally entitled to possess a protected firearm but is effectively prevented from obtaining one through the ordinary commercial market, the restriction can still substantially interfere with the right to keep and bear arms.
The Justice Department therefore concluded that criminally enforcing the federal sales restriction against otherwise eligible 18–20-year-old adults would violate the Second Amendment.
The History Behind the Decision
The DOJ opinion relies heavily on the historical approach required by the Supreme Court's Second Amendment decisions.
Under the framework established by the Supreme Court in New York State Rifle & Pistol Association v. Bruen, when conduct falls within the Second Amendment's plain text, the government must identify a sufficiently relevant historical tradition supporting the challenged restriction.
OLC examined historical laws concerning young adults and firearms and concluded that the government could not identify a comparable founding-era tradition that prohibited adults ages 18 to 20 from acquiring handguns.
One historical point highlighted in the opinion is particularly notable: early American militia laws commonly placed 18-year-olds into the militia system and required them to provide their own arms.
The opinion also considered historical restrictions on minors and contractual capacity but found those rules substantially different from a modern federal prohibition backed by criminal penalties against licensed firearm dealers.

This Is Not the Same as Repealing the Law
Here's the part firearm owners need to keep straight.
The federal statutes remain on the books.
Congress has not repealed the age restriction. The DOJ opinion instead takes the position that enforcing the restriction against otherwise eligible 18–20-year-old adults would violate the Constitution.
That creates practical questions involving federal agencies, licensed dealers and the background-check system.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has historically enforced the federal age restrictions, while the FBI operates the National Instant Criminal Background Check System (NICS). How those systems implement the Justice Department's new position is therefore significant.
State Laws Are a Separate Matter
Another important limitation: the DOJ opinion concerns federal law.
States can have their own age restrictions, and the federal government's position does not automatically invalidate those laws.
So an 18-, 19-, or 20-year-old should not assume that the DOJ announcement by itself makes a handgun purchase lawful under every state or local law.
The applicable federal and state rules still need to be checked.
The Fifth Circuit Already Reached a Similar Conclusion
The DOJ's position also follows significant federal court litigation.
In Reese v. ATF, the Fifth Circuit concluded that the federal restrictions on licensed dealers selling handguns to adults ages 18 to 20 were inconsistent with the Second Amendment.
That decision applied within the Fifth Circuit rather than automatically changing federal law nationwide.
The new DOJ opinion represents a broader change in the federal government's own legal position.
An Office of Legal Counsel opinion is not the same thing as a ruling from the U.S. Supreme Court, and it does not eliminate the underlying statutes.
What Comes Next?
The immediate question is implementation.
Federal agencies and firearms dealers will have to reconcile existing statutory language and regulations with DOJ's new constitutional interpretation.
There are also likely to be continuing court fights over age-based firearm restrictions, particularly where state laws impose their own limits.
For anyone following Second Amendment law, this development is significant because the federal government's position has changed on a restriction that has been in place for decades.
For firearm owners, however, the practical takeaway is simple:
Don't confuse a DOJ constitutional determination with a congressional repeal of the law.
