A step-by-step guide to purchasing firearms safely and legally on American Gun Trader — from finding a listing to completing the FFL transfer.
For a typical private purchase from a seller who lives in another state, complete the transfer through an FFL in your state of residence. The dealer will verify your identity, complete ATF Form 4473, and conduct the required background check before releasing the firearm. Some states also require FFL transfers for private in-state sales. Buyers must meet applicable age and eligibility requirements. Confirm current federal, state, and local laws before purchasing, as rules vary by jurisdiction.
Follow these five essential steps to legally purchase a firearm.
Browse listings from private sellers and licensed FFL dealers nationwide. Filter by caliber (9mm, .308), manufacturer, condition, price range, and seller's state. Filtering by state first helps you spot private-party options where an in-person transfer may be legal without an FFL.
Browse firearmsNot every firearm is legal in every state. Research your local laws before committing — including for out-of-state sellers. Magazine-capacity limits and feature bans vary widely by jurisdiction.
Check state gun lawsUse AGT's built-in secure messaging — no email address required. Confirm condition and accessories, negotiate the price, and agree which FFL will receive the transfer if the sale is interstate. In-state, private-party handoffs may be allowed where your state permits them.
For a typical private sale from a resident of another state, arrange transfer through an FFL in your state of residence. You will provide valid ID and complete the dealer's required paperwork and background check. Even in-state sales may require an FFL depending on state law.
Verify FFL licenseWhen the firearm arrives, the dealer schedules pickup. Bring a valid photo ID, complete ATF Form 4473, and the FFL runs a NICS background check — usually approved within minutes. Some states impose waiting periods (e.g., California requires 10 days) before pickup.
What to avoid and who is eligible to buy a firearm.
Start on a classifieds marketplace like American Gun Trader, find a listing from a private seller or FFL dealer, and message the seller to confirm availability, condition, and transfer details. For a typical private sale from a resident of another state, arrange transfer through a licensed FFL in your state of residence, where you present valid government ID, complete ATF Form 4473, and complete the required background check before pickup. Some states also require FFL involvement for certain in-state private sales, and age limits apply — 18 for long guns and 21 for handguns from FFLs under federal rules, with stricter state laws possible. Research your state and local restrictions before you buy — magazine capacity, feature bans, and waiting periods vary widely. Use moderated platform messaging rather than off-site contact info, verify the receiving FFL license on the ATF EZ Check site, and never agree to evade background checks.
Yes. For a typical private purchase from a seller who lives in another state, the firearm must be transferred through an FFL in the buyer's state of residence. The buyer completes ATF Form 4473 and the dealer conducts the required background check before release. Some states also require FFL transfers for private in-state sales.
An FFL transfer is when a Federal Firearms License holder receives a firearm for the buyer, verifies identity, completes ATF Form 4473, and conducts the required background check before release. For a typical private interstate sale, the receiving FFL is in the buyer's state of residence. Verify a dealer using ATF eZCheck.
For a typical private purchase from a seller in another state, the firearm is transferred through an FFL in the buyer's state, where the dealer conducts the required background check. Some states also require checks for in-state private sales. A check may be delayed or require further review.
Under 18 U.S.C. Section 922(g), prohibited persons include anyone with a felony conviction, domestic violence conviction, active restraining order, fugitive status, felony indictment, history of involuntary mental health commitment, unlawful controlled substance use, or non-citizen status (with limited exceptions). Buyers must be at least 18 for long guns or 21 for handguns from licensed dealers.
ATF Form 4473 (Firearms Transaction Record) is a federal form that must be completed by anyone purchasing a firearm from an FFL dealer. It collects the buyer's personal information and asks eligibility questions to determine whether the buyer is legally allowed to purchase a firearm. Providing false information on Form 4473 is a federal felony.
The typical timeline for buying a gun online is 5 to 10 business days. This includes 1-2 days to arrange the sale with the seller, 2-5 days for shipping to your local FFL dealer, and 1-3 days for the FFL to process the transfer and background check. Some states have mandatory waiting periods that may add additional days.
