Can You Buy a Gun at 18 in Washington? Age Rules and Exceptions
Sometimes. In Washington, an 18-year-old may generally buy certain rifles and shotguns from a federally licensed dealer, but cannot buy a handgun or a semiautomatic assault rifle from a dealer until age 21. Private transfers, gifts, possession, and transport have separate rules, and federal law still applies. The details depend on the firearm and how it is transferred, so a buyer should check current state and federal requirements before taking possession.
Washington’s Minimum Gun-Buying Ages
There is no single minimum age that covers every firearm transaction. The key distinctions are the firearm type, whether the seller is a licensed dealer or a private person, and whether the transfer is a sale or another kind of transfer. Federal law sets a minimum age for purchases from licensed dealers, while Washington adds restrictions of its own.
| Firearm or transaction | General rule for an 18-year-old |
|---|---|
| Rifle or shotgun from a licensed dealer | Generally allowed at 18, subject to state restrictions and background-check requirements |
| Handgun from a licensed dealer | Not allowed until age 21 |
| Semiautomatic assault rifle from a licensed dealer | Not allowed until age 21 |
| Private transfer or gift | Rules depend on firearm type, relationship, transfer method, and applicable state and federal law |
These are general age rules, not a guarantee that a particular transaction is lawful. A person may also be prohibited from possessing a firearm for reasons unrelated to age, such as certain criminal convictions or court orders.
Buying a Rifle or Shotgun at 18
Federal law generally allows a federally licensed firearms dealer to sell a rifle or shotgun to a person who is at least 18. Washington does not impose a general age-21 rule on every ordinary rifle or shotgun purchase. However, Washington restricts dealer sales of semiautomatic assault rifles to people under 21, so the ordinary long-gun rule does not cover every rifle.
“Semiautomatic assault rifle” is a term defined in Washington law. It includes certain semiautomatic rifles that meet the state’s statutory definition; it is not simply a label for every semiautomatic firearm. Because classification can depend on the firearm’s features and design, a prospective buyer should not assume a rifle is exempt based on its name or appearance. Washington’s Attorney General and state statutes provide information on the current definition and restrictions.
An eligible 18-year-old purchasing a nonrestricted rifle or shotgun from a dealer must still complete the required paperwork and background-check process. A dealer must follow federal and state law and may decline a transaction that raises a legal or safety concern. The buyer should bring valid identification and allow time for any waiting period or additional review that applies.
Why an 18-Year-Old Cannot Buy a Handgun From a Dealer
Federal law generally bars federally licensed dealers from selling handguns to people under 21. Washington law also sets age-21 restrictions for dealer delivery of pistols. As a result, an 18-, 19-, or 20-year-old generally cannot buy a handgun directly from a gun store in Washington, even if the person is otherwise legally eligible to possess firearms.
That restriction concerns a dealer sale. It does not mean every form of handgun possession by an adult under 21 is automatically unlawful. But a private transfer is not a simple workaround: Washington’s rules on transfers and delivery, federal law, and any applicable exceptions all need to be considered. The legal answer may differ depending on whether the firearm is sold, gifted, inherited, or loaned, and on the relationship between the people involved.
Private Sales, Gifts, and Family Transfers
Washington generally requires firearm transfers between private parties to go through a licensed dealer for a background check, unless a statutory exception applies. Some transfers between qualifying family members are exempt from that dealer process under state law. An exemption from a background-check procedure, however, does not automatically remove age restrictions or make a transfer lawful under federal law.
Federal law permits some transfers of firearms between private individuals who live in the same state, provided the recipient is not prohibited from possessing firearms and the transfer does not violate state law. Federal rules also restrict certain transfers to people under 18, but those rules do not settle every question for an 18-to-20-year-old in Washington. State restrictions and the type of firearm still matter.
For example, an 18-year-old considering a handgun from a relative should not rely only on the fact that the transfer is a gift or that the parties are family. The parties should confirm that the relationship and transaction meet the relevant statutory exception, that the firearm’s transfer is permitted at the recipient’s age, and that no other restriction applies. When the law is unclear, the safest course is to ask a Washington firearms attorney or the Washington State Department of Licensing rather than proceed based on an informal interpretation.
Possession Is Different From Buying
Age limits on purchases do not answer every question about possession. Washington generally restricts possession by people under 18, subject to exceptions such as certain supervised activities. An 18-year-old is no longer covered by that general under-18 restriction, but must still comply with laws governing prohibited persons, firearm locations, safe storage, and use.
Possession also does not establish that the firearm was lawfully acquired. A person can face legal consequences for receiving a firearm through an unlawful transfer even if the person is old enough to possess that type of firearm. Conversely, a rule that prevents an under-21 dealer purchase does not, on its own, describe every lawful way an adult under 21 may handle or possess a firearm. The details depend on the specific circumstances.
Background Checks, Waiting Periods, and Purchase Permits
Washington requires background checks for most firearm transfers, including many private transactions. The process may involve a dealer and the appropriate state or local authority. A background check is not just a formality: the transfer cannot lawfully proceed if the buyer is prohibited or if required checks and approvals have not been completed.
Washington has also enacted additional requirements affecting firearm purchases, including safety-training and waiting-period provisions. The state’s permit-to-purchase framework has an implementation timeline, so requirements may depend on the date of a transaction. Because statutes, effective dates, and agency procedures can change, buyers should check current instructions from the Washington State Department of Licensing and the Washington State Patrol before attempting a purchase.
Even when a buyer meets the minimum age, the transaction may be delayed. A background check may require additional review, and Washington law can require a waiting period before delivery. Buyers should not assume that paying for a firearm means they can take it home the same day.
Other Reasons a Person May Be Barred From Buying or Possessing a Gun
Age is only one part of eligibility. Federal and Washington law prohibit firearm possession by certain people. Disqualifiers may include specified felony convictions, some domestic-violence convictions or protection orders, certain court findings related to mental health, and other legal conditions. The precise effect depends on the law, the person’s record, and whether rights have been restored.
A person who is uncertain about a past conviction, order, or other possible disqualifier should get legal advice before attempting to buy or possess a firearm. A dealer’s background-check result is not a substitute for a legal determination, and an incorrect application or unlawful possession can create serious consequences.
Safe Storage and Transport in Washington
Washington law includes safe-storage requirements, particularly when a person knows or reasonably should know that a prohibited or underage person could access a firearm. Firearms should be secured against unauthorized access, with additional care around children and visitors. A locked container or suitable locking device can reduce the risk of accidental injury, theft, and unlawful access.
Transport rules also matter. A firearm should be transported in compliance with state law and any rules that apply to the vehicle, location, and firearm type. Carrying a concealed pistol generally involves separate legal requirements; being old enough to possess a firearm does not automatically authorize concealed carry. Restrictions can also apply in schools, government buildings, and other designated locations.
How to Check Before Buying
- Identify the firearm. Determine whether it is a handgun, an ordinary rifle or shotgun, or a rifle that meets Washington’s definition of a semiautomatic assault rifle.
- Identify the seller and transfer type. A dealer sale, private sale, family gift, inheritance, and loan may be treated differently.
- Check age restrictions. Confirm both federal dealer rules and Washington’s rules for that firearm and transaction.
- Confirm current procedures. Ask a licensed dealer about background checks, waiting periods, required training, and any permit requirement in effect on the transaction date.
- Resolve eligibility concerns first. If a court order, conviction, or other possible prohibition applies, seek qualified legal advice before possessing or receiving a firearm.
Reliable Sources for Current Rules
Washington firearm laws are set out primarily in the Revised Code of Washington, including provisions on dealer transfers, private transfers, age restrictions, and firearm possession. The Bureau of Alcohol, Tobacco, Firearms and Explosives explains federal dealer requirements and federal firearm laws. The Washington State Department of Licensing provides state firearm information, while the Washington State Patrol publishes background-check guidance.
Bottom line: An 18-year-old in Washington can generally buy an eligible, nonrestricted rifle or shotgun from a licensed dealer, but cannot buy a handgun or a semiautomatic assault rifle from a dealer until age 21. Private transfers and gifts require separate analysis; they are not automatically lawful simply because the recipient is 18. Checking the current statute and transfer procedure before acting is essential.
