Do Stripped Lowers Have to Be Shipped to an FFL?
Usually, yes—when a stripped lower is shipped across state lines to a buyer, it generally must go to a federally licensed firearms dealer (FFL) for transfer. Federal law treats a serialized lower receiver as a firearm, even when it has no stock, barrel, or other parts installed. The exact requirements depend on who is sending it, where the sender and recipient live, and state and local law.
This guide explains the general federal rules, common shipping situations, age considerations, and practical steps buyers and sellers can take. It is general information, not legal advice; state laws and carrier policies can impose additional requirements.
Why a Stripped Lower Is Considered a Firearm
A stripped lower receiver is not a complete, functioning rifle. However, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) generally regulates the lower receiver of an AR-style firearm as the firearm itself under the Gun Control Act. It is the serialized component commonly recorded in a dealer’s acquisition and disposition records.
That means a lower does not stop being a regulated firearm simply because it is stripped of its upper receiver, stock, trigger group, or other components. If it is a receiver that federal law treats as a firearm, the ordinary rules for firearm transfers apply. A buyer should not assume that a stripped lower can be mailed or transferred like an ordinary metal part.
Some designs and products require case-specific classification. A part that is unfinished, partially finished, or marketed as an “80% lower” is not automatically a firearm—or automatically exempt—because of its label. ATF classification can depend on the item’s design and how much work is needed to make it function as a receiver. State law may define or regulate unfinished receivers differently.
When a Stripped Lower Must Go to an FFL
Shipment to a buyer in another state
When a seller ships a stripped lower to a buyer who resides in a different state, the normal procedure is to ship it to an FFL in the buyer’s state. The receiving dealer then completes the transfer to the buyer, including the required ATF Form 4473 and any applicable background check.
Federal law generally prohibits an unlicensed person from transferring a firearm directly to an unlicensed person who resides in another state. A common lawful route is for the seller to send the lower to a dealer in the buyer’s state. The buyer completes the transfer there, subject to federal, state, and local rules.
Purchase from an out-of-state dealer
A dealer generally cannot hand a firearm directly to an out-of-state buyer unless a specific federal exception applies. For a stripped lower, the usual process is shipment to an FFL in the buyer’s state, where the buyer completes the transfer. The destination dealer may charge a transfer fee and may require advance notice or a copy of the sending dealer’s license.
Private sale within the same state
Federal law generally allows a private, face-to-face transfer between residents of the same state when the transfer is otherwise lawful and the seller does not know or have reasonable cause to believe the buyer is prohibited from possessing firearms. But that general federal rule does not override state or local requirements.
Some states require private transfers to be handled through an FFL, require a background check, impose waiting periods, or restrict particular firearm parts or configurations. A state may also regulate stripped receivers more strictly than federal law does. Before arranging an in-state sale, both parties should check the rules where the transfer will take place.
Common Shipping Situations
| Situation | General federal approach |
|---|---|
| Seller ships a lower to a buyer in another state | Ship to an FFL in the buyer’s state for transfer to the buyer. |
| Buyer purchases from a dealer in another state | The lower generally goes to an FFL in the buyer’s state. |
| Two residents of the same state make a private transfer | An FFL is not always required under federal law, but state and local rules may require one. |
| Owner sends a personally owned lower to an FFL for work | A transfer to an FFL may be possible without using a dealer as a buyer’s transfer intermediary; confirm the dealer’s process and shipping rules. |
| Owner moves to another state with a lower | Personal relocation is different from a sale; check the destination state’s possession and transport laws. |
Shipping a Lower for Repair or Other Service
An owner may need to send a personally owned firearm to a gunsmith or another FFL for repair. That is different from shipping it to an out-of-state private buyer. Federal regulations provide for certain transfers between an unlicensed person and an FFL, but the business should confirm whether it will accept the item, how it wants it shipped, and how it will return it.
For an owner who ships a firearm to an FFL for repair, federal rules generally allow the FFL to return the firearm to the same person without treating the return as a sale, provided the legal conditions are met. If the owner wants the dealer to send it to a different person, or the firearm is not being returned to the person who sent it, the transfer may require a different process. The dealer should determine how to handle the situation before shipment.
Carrier rules are separate from federal transfer rules. A carrier may have its own limits on who can ship firearms, which locations can accept them, how they must be packaged, and what service level is required. Policies can change, so the shipper should check the current rules directly with the carrier and the receiving FFL.
Age Rules for Buying a Stripped Lower
Age requirements can be confusing because a stripped lower is not necessarily classified as a complete rifle or shotgun. Federal law bars a federally licensed dealer from selling or delivering firearms other than rifles or shotguns to a person under 21, subject to limited statutory exceptions. Because a stripped lower is generally treated as a firearm but is not itself a complete rifle or shotgun, dealers commonly apply the 21-and-older rule.
That federal dealer rule does not answer every question about private transfers, possession, or state law. State minimum-age rules may be higher or may apply differently. A dealer may also have a policy stricter than the minimum legal requirement. Buyers should confirm the applicable age rule with the receiving FFL and check state law before paying for a lower.
What the FFL Transfer Usually Involves
After the lower arrives, the receiving dealer records it in the dealer’s required inventory records and contacts the buyer according to its procedures. Before taking possession, the buyer generally completes ATF Form 4473 and undergoes the required background-check process unless a lawful exception applies. The dealer must follow applicable federal, state, and local requirements.
The FFL may ask the buyer to provide identification, complete state-specific forms, or satisfy a waiting period. Some states require permits, additional background checks, or other steps. A dealer can refuse a transfer if the buyer is ineligible, required documentation is missing, or the transaction would violate the dealer’s understanding of applicable law.
Transfer fees are set by the receiving dealer, not by a single nationwide federal fee schedule. The buyer should ask about the fee, accepted identification, expected processing time, and whether the dealer requires the seller to include particular paperwork. The buyer should also confirm that the dealer will accept a shipment from the specific seller or carrier.
State Laws Can Change the Answer
Federal law sets a baseline, but it does not provide a complete answer for every location. State and local laws may require background checks for private transfers, impose waiting periods, regulate certain firearm features, set minimum ages, or restrict possession of particular receivers. Some jurisdictions have additional rules for unfinished frames and receivers, including registration or serialization requirements.
Rules can also differ depending on the lower’s intended configuration. A stripped lower may be regulated as a firearm on its own, while the assembled firearm may be subject to separate restrictions based on its features or configuration. Buyers should not assume that a lawful receiver transfer automatically makes every later assembly lawful.
Before ordering, the buyer should check the law in the state and locality where the lower will be received and possessed. The receiving FFL is a useful source for its transfer procedures, but the dealer is not a substitute for legal advice and may not interpret every local rule. If the rules are unclear, consulting a qualified attorney or the relevant state agency is prudent.
Practical Checklist Before Ordering or Shipping
- Confirm the item’s classification. Make sure the product is a receiver regulated as a firearm, rather than assuming its status from a seller’s description.
- Ask the receiving FFL first. Confirm that it accepts stripped lowers, accepts shipments from the proposed sender, and is willing to complete the transfer.
- Check state and local requirements. Verify private-transfer rules, age limits, waiting periods, permits, and any receiver-specific restrictions.
- Use the correct destination. For an interstate sale to an individual, arrange shipment to an FFL in the buyer’s state rather than directly to the buyer.
- Follow current carrier rules. Confirm packaging, account, notification, and service requirements with the carrier before tendering the package.
- Coordinate paperwork and fees. Ask whether the dealer needs the seller’s information, a copy of a license, or advance notice, and confirm the transfer fee.
- Keep records. Retain receipts, shipment tracking, and relevant transfer documentation, and ensure the transaction follows the applicable law.
Reliable Sources for Checking the Rules
The ATF’s federal firearms regulations and guidance explain how licensed dealers handle firearm transactions and records. Relevant federal statutes include 18 U.S.C. § 922, which covers unlawful firearm transfers and age-related restrictions, and 18 U.S.C. § 921, which defines key terms used in federal firearms law. Current text is available through the U.S. Code, and ATF resources are available at ATF.gov/firearms.
For a specific shipment, the receiving FFL and carrier should be consulted directly because their procedures and service rules may change. For state-specific restrictions, the state’s official statutes or law-enforcement agency are more reliable than informal forum posts or seller listings.
The Bottom Line
A stripped lower generally must be shipped to an FFL when it is being transferred to a buyer who lives in another state. A same-state private transfer may not require an FFL under federal law, but state and local requirements can change that answer. Because receivers are regulated firearms and carrier policies are separate from transfer law, buyers and sellers should verify the destination dealer, applicable local rules, and current shipping requirements before sending or ordering a lower.
