Active-duty service members can buy firearms in the state where they are stationed and in a state where they otherwise maintain residency, but not in just any state they happen to visit. Federal law treats a service member on active duty as a resident of the state containing their permanent duty station, which opens the door at licensed dealers there. It does not make you a resident of every state you pass through, and it does not override any of that state’s own firearm laws.
Why Your Duty Station Counts as Home
Federal law generally bars licensed dealers from selling firearms to people who live outside the dealer’s state. A single sentence in the U.S. Code carves out service members: a member of the Armed Forces on active duty is a resident of the state where their permanent duty station is located.1Office of the Law Revision Counsel. 18 U.S. Code 921 – Definitions Federal regulations say the same thing.2eCFR. 27 CFR 478.11 – Meaning of Terms Without this rule, a soldier from Texas assigned to Fort Liberty in North Carolina could not buy a handgun from a North Carolina dealer.
Many service members end up with dual residency. You are a resident of your duty station state for firearm purposes, and you can remain a resident of another state if you keep a home there or intend to return. ATF guidance says a service member claiming residency somewhere other than the duty station has to show physical presence with the intent to make a home in that state.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide – Section: Military Members on Active Duty Have Special Residency Considerations So buying a firearm in your home-of-record state while on leave is fine, provided you actually maintain a home there.
If you’re stationed in one state but living off-post in a neighboring one, both addresses matter. When you complete the ATF Form 4473 at a dealer, you list your duty station address and your residential address.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide – Section: Military Members on Active Duty Have Special Residency Considerations
What to Bring to the Dealer
Two things prove you belong at that counter: identification and proof you’re stationed in the state. ATF guidance identifies a valid military photo ID paired with PCS orders (paper or electronic) covering your assignment to a duty station in the state as sufficient to establish residency.3Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Firearms Licensee Quick Reference and Best Practices Guide – Section: Military Members on Active Duty Have Special Residency Considerations Some dealers also accept a local driver’s license or utility bills showing a local address, but the ID plus orders combination is the cleanest path.
The dealer then has you fill out ATF Form 4473 and runs a background check through the National Instant Criminal Background Check System.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Firearms Transaction Record – ATF Form 5300.9 If the check clears and no state waiting period or permit applies, you leave with the firearm the same day.
Age Limits Apply Just Like Anyone Else
Federal law sets the minimum age for buying a long gun from a licensed dealer at 18, and a handgun at 21.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Active-duty status does not change this. A 19-year-old infantryman who carries a sidearm on deployment still can’t buy a handgun from a licensed dealer stateside until he turns 21. It surprises a lot of younger troops.
Since 2022, buyers aged 18 to 20 also face an enhanced background check under the Bipartisan Safer Communities Act. The NICS system contacts additional repositories, including state juvenile justice and mental health records and local law enforcement, when running the check.6United States Congress. S.2938 – Bipartisan Safer Communities Act That review can add processing time, so if you’re in that age band, don’t assume a same-day transfer.
State Laws Still Control the Sale
This is where the “any state” idea really breaks down. The federal residency rule gets you through the door. It does not exempt you from the state’s own firearm rules. Whatever applies to civilian residents applies to you.
Some states require a separate purchase permit before you can buy a handgun. Others impose waiting periods between the sale and the transfer. Several ban specific firearm configurations or limit magazine capacity. A service member who PCSes from a permissive state to a restrictive one may discover that a rifle they planned to buy is either unavailable or has to be sold in a modified form. The dealer follows the law of the state they’re in, regardless of where you came from, so check the state’s rules before you make the drive.
Spouses Don’t Get the Same Rule
The residency exception applies only to the active-duty member. A military spouse cannot use PCS orders to establish residency for a firearm purchase in the duty station state. Instead, the spouse has to independently show they live there, usually with a state-issued ID or driver’s license carrying a local address. For a spouse who just arrived at a new installation and hasn’t gotten local ID yet, that is a real barrier.
Legislative proposals to extend the exception to spouses have been introduced, but as of 2026 none have been signed into law. The practical workaround is to get a driver’s license or state ID in the new state, or gather enough supporting documentation (local vehicle registration, utility bills, voter registration) to satisfy the dealer. A spouse who keeps residency in the home-of-record state can also buy there, but only during a physical visit to a dealer in that state.
Discharge Status and Federal Prohibitions
Anyone discharged from the Armed Forces under dishonorable conditions is prohibited under federal law from possessing firearms or ammunition.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts The ban is lifetime unless the discharge is upgraded or the person receives a presidential pardon.
The statute uses the specific phrase “dishonorable conditions,” which refers to a Dishonorable Discharge issued by a general court-martial. Other characterizations that sound similar are legally distinct: an Other Than Honorable discharge or a Bad Conduct Discharge from a special court-martial does not automatically trigger the federal prohibition.7Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Some states do have broader prohibitions that reach further, so confirm your status under state law before assuming you can purchase.
The other federal prohibited categories under 18 U.S.C. ยง 922(g) apply to service members the same as anyone else: felony convictions, domestic violence misdemeanor convictions, active domestic violence restraining orders, unlawful drug use, adjudication as mentally defective, and several others.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts
Moving the Firearm to a New Duty Station
A PCS often means crossing states with very different firearm laws. The Firearms Owners’ Protection Act gives you safe passage to transport a firearm through any state as long as you can legally possess it at both your origin and your destination. During transport, the firearm must be unloaded and stored where it is not readily accessible from the passenger compartment. In a vehicle without a separate trunk, it has to be in a locked container other than the glove compartment or console. Ammunition follows the same accessibility rules.8Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
Safe passage protects transit, not extended stays. Overnight stops and hotel storage in restrictive states have caused problems for travelers who assumed the federal rule covered everything. Plan your route and stops accordingly.
Flying is a separate framework. TSA allows firearms in checked baggage if they are unloaded and locked in a hard-sided container, and if you declare the firearm to the airline at the ticket counter. Ammunition can travel in checked baggage as well, packed in its original box or a container designed for it, and it can share the locked case. Only you should hold the key or combination. Nothing firearm-related goes in a carry-on.9Transportation Security Administration. Transporting Firearms and Ammunition
Bringing the Firearm Onto the Installation
Legally buying a firearm off-post doesn’t mean you can freely bring it through the gate. Each installation sets its own policy on privately owned firearms, and those policies are often stricter than state law.
Most installations require you to register the firearm with the provost marshal or military police within a short window after bringing it on post, commonly 72 hours. Storage rules follow where you live. Service members in barracks or bachelor quarters are generally required to store personal firearms in the unit arms room rather than in their rooms. Those in on-post family housing can usually keep firearms in their quarters with written commander approval, but registration is still required. If you live off-post, installation rules typically don’t restrict storage in your private residence, but you still have to register any firearm you plan to bring onto the installation for any purpose, even briefly. Moving an unregistered personal weapon past the gate can bring UCMJ consequences even if the firearm is perfectly legal under state and federal law. Read the installation’s specific policy before the firearm crosses onto post.
