Before You Purchase A Gun

What Do I Need To Buy A Gun?

Answer teThe requirements to buy a gun depend on your location, but in the U.S., here are the general steps:

  • Age Requirement
  • Background Check
  • Valid Identification
  • Residency Requirement
  • Firearm License or Permit (If Required)
  • Waiting Period (If Applicable)
  • State-Specific Laws
Is it legal to buy a gun online?

Yes, buying a gun online is completely legal in the U.S., but the firearm must be shipped to a Federal Firearms License (FFL) dealer in your state. You’ll need to pass a background check and complete any required paperwork before taking possession of the firearm.

Do I need a background check to buy a gun online?

Yes. Even when purchasing online, a background check is required at the FFL dealer where you pick up your firearm (unless you have a permit that exempts you in your state). The FFL dealer will conduct the check before handing over the gun.

Can I have a gun shipped directly to my house?

No, firearms cannot be shipped directly to your home. They must be sent to a licensed FFL dealer, where you will complete the legal transfer process. However, ammo and accessories can be shipped directly to your residence in most states.

How do I choose an FFL dealer for my transfer?

Many online gun stores allow you to select an FFL dealer during checkout. If not, you’ll need to find a local gun shop or licensed dealer willing to handle the transfer and provide their information to the seller.

After You Purchase A Gun

What happens after I purchase a gun online?

After completing your purchase, your firearm will be shipped to a Federal Firearms License (FFL) dealer near you. You’ll receive tracking information and instructions on how to pick up your firearm.

What do I need to do after purchasing a gun online?

After purchasing, provide the seller with the information of your chosen FFL dealer (they will handle the transfer). Once the firearm arrives at the dealer, you’ll go there, complete the required background check and paperwork, and then take your firearm home after approval.

What do I need to bring when picking up my gun?

When you arrive at the FFL dealer, bring:

  • A valid government-issued ID (matching the address on your order).
  • Any required permits or licenses (varies by state).
  • Payment for the FFL transfer fee (usually $25-$75, depending on the dealer).
Do I have to pass a background check when picking up my gun?

Yes. Even if you bought the gun online, you must pass a background check (NICS) at the FFL dealer before taking possession of your firearm.

Can I return the gun if I change my mind?

The Supplier determines shipping methods for firearms which ship from a Supplier. Shipping charges for firearms are calculated separately from other products on your order and will incur a separate Per Order charge. Due to Federal regulations, guns are not returnable. Please inspect your gun thoroughly before transfer. If the gun received at the FFL Dealer is incorrect or damaged in shipment, do not take possession of the gun and please contact Customer Service. After transfer, any warranty or repair work must be coordinated directly with the gun manufacturer. Firearms refused by the FFL Dealer or which cannot be transferred due to a failed background check will be subject to a 10% restocking fee.
