You turn eighteen and suddenly the world opens up. You can vote, you can sign a lease, and in the eyes of the government, you're an adult. But then you walk into a gun shop and things get... weird. Depending on where you live, the clerk might hand you a bolt-action .30-06 with a smile, or they might tell you to come back in three years. Honestly, the laws regarding whether or not can you buy a rifle at 18 are a patchwork quilt of federal mandates and local politics that change the moment you cross a state line.
Federal law is the baseline. It says you can buy a "long gun"—which includes rifles and shotguns—from a licensed dealer once you hit eighteen. Handguns? Nope. You have to wait until you're twenty-one for those. But that's just the surface level. Since 2022, the federal government has added layers of scrutiny for younger buyers that didn't exist for decades.
The Bipartisan Safer Communities Act Changed the Game
If you’re eighteen and trying to buy a rifle today, you aren't just dealing with the standard NICS background check that takes ten minutes. The Bipartisan Safer Communities Act, signed into law in June 2022, specifically targeted buyers under twenty-one. Now, the FBI is required to contact state and local law enforcement to check for juvenile records or mental health adjudications that might not show up in the national database.
It’s a waiting game.
Even if you have a clean record, there is often a mandatory investigative period. This can trigger a delay of up to ten business days. It isn't a "denial," but it’s a pause that feels like an eternity when you're just trying to go hunting with your dad. The law essentially says that while you can buy the rifle, the government wants a much longer look at your history than they do for a forty-year-old.

State Laws Are Making Federal Rules Irrelevant
Forget what the federal government says for a second. States like California, Florida, and Washington have looked at the federal "eighteen-and-up" rule and decided it wasn't enough. In Florida, the Marjory Stoneman Douglas High School Public Safety Act raised the age to purchase any firearm—rifles included—to twenty-one. This was a massive shift for a state known for its relatively relaxed gun laws.
If you live in Vermont? Twenty-one.
Hawaii? Twenty-one.
Illinois? You need a FOID card, and if you’re under twenty-one, you generally need a parent’s consent, and even then, there are massive hurdles.
It’s frustrating for young adults who might be serving in the military. Think about the irony. A nineteen-year-old soldier can be trusted with an M4 carbine in a combat zone, but if they come home to a state like California on leave, they might be legally barred from buying a Remington 700 for deer season. Some states offer exemptions for active-duty military or law enforcement, but not all of them. You’ve really got to check the specific penal codes of your zip code.
Private Sales vs. Licensed Dealers
Here is a nuance people often miss: the difference between a Federal Firearms Licensee (FFL) and a private seller.

Under federal law, the age restriction of eighteen applies to FFLs—the guys with the storefronts. In many states, if your grandfather wants to sell you his old Winchester or give it to you as a gift, that is perfectly legal at eighteen (or sometimes even younger, depending on the state). However, this is a legal minefield. States like New York or Oregon have basically killed the "private sale" loophole by requiring all transfers to go through a dealer anyway.
If you try to bypass a dealer in a state that requires universal background checks, you aren't just "buying a rifle." You're committing a felony.
What About "Assault Weapons" Bans?
The term "rifle" is broad. A wood-stocked Ruger 10/22 is a rifle. An AR-15 is also a rifle. But in the eyes of many state legislatures, they are worlds apart. Even if a state allows you to buy a rifle at eighteen, they might specifically ban "semiautomatic centerfire rifles" for anyone under twenty-one.
Washington state’s Initiative 1639 did exactly this. It reclassified basically all semiautomatic rifles as "semiautomatic assault rifles" and bumped the age to twenty-one. So, at eighteen, you can buy a bolt-action or a lever-action, but that modern sporting rifle you wanted for target practice? Off-limits. It's a distinction based on the action of the firearm, not just the age of the person holding it.

Why the Background Check Takes Longer Now
Let’s talk about the NICS (National Instant Criminal Background Check System). When an eighteen-year-old fills out Form 4473, the system automatically flags the birthdate.
- The FBI checks the standard databases (Interstate Identification Index, NCIC, and NICS Index).
- They then reach out to state repositories.
- They contact local police departments to see if there are any "disqualifying factors" from when the buyer was sixteen or seventeen.
In the past, juvenile records were often sealed or ignored for gun purchases. Not anymore. If you had a run-in with the law at sixteen that involved a "crime of violence," that could potentially haunt your ability to buy a rifle at eighteen. Most people don't realize that the "clean slate" of adulthood has some cracks in it when it comes to the Second Amendment.
Practical Steps for the 18-Year-Old Buyer
If you are serious about purchasing, don't just wing it.
First, look up your state’s "Minimum Age to Purchase and Possess" laws. Don't use a random forum; go to the official state police or Attorney General website. Second, expect a delay. Don't plan a hunting trip for the day after you go to the shop. Give it two weeks for the background check to clear.
Third, bring the right ID. A vertical "Under 21" driver's license is fine as long as it’s valid and has your current address, but some dealers get jumpy about them. Make sure your address on your ID matches exactly where you live. If you’ve moved for college and haven't updated your license, you're going to get rejected on the spot.
Actionable Next Steps:
- Check State Preemption: Determine if your city has stricter laws than your state. In some places, like New York City, the rules are drastically different from the rest of the state.
- Verify Military Exemptions: If you are 18-20 and in the military, carry your active duty ID and orders. Some states that ban sales to under-21s make an exception for you.
- Consult an FFL: Go talk to a local gun store owner. They deal with these laws every single day and know the specific hurdles in your town.
- Review Juvenile Records: If you have a "record" from your teens, consult a lawyer to see if it’s a disqualifying offense before you try to fill out a 4473 and risk a "denied" status.
- Prepare for the Wait: Budget for a 10-day delay in your timeline to account for the enhanced NICS check mandated by the Bipartisan Safer Communities Act.
