AK-47s are legal to own in the United States in their common semi-automatic form under federal law and in most states, but genuine fully automatic AK-47s are tightly restricted, roughly a dozen states ban the platform outright, and configuration details like barrel length, magazine capacity, and imported parts can change the answer. Where you live and how the rifle is built decide which rules apply.
Federal Law on Semi-Automatic AK Rifles
The semi-automatic AK-pattern rifles sold in American gun stores are not covered by any AK-specific federal statute. The 1994 assault weapons ban under the Violent Crime Control and Law Enforcement Act expired in 2004, and nothing has replaced it. Semi-auto AKs are regulated as standard long guns under the Gun Control Act.
The dimensions that matter come from the National Firearms Act. A rifle needs a barrel of at least 16 inches and an overall length of at least 26 inches. Anything shorter becomes a “short-barreled rifle,” which requires NFA registration, a $200 tax, and ATF approval before you can possess it.1Office of the Law Revision Counsel. 26 U.S. Code 5845 – Definitions Factory AK rifles from licensed dealers clear both numbers, so at the federal level the purchase looks like buying any other rifle.
Who Cannot Legally Own One
Federal law bars several categories of people from possessing any firearm or ammunition. The most common disqualifiers are:
- A felony conviction, meaning any crime punishable by more than one year in prison, whether or not you served time.
- A misdemeanor domestic violence conviction, or an active restraining order tied to an intimate partner or their child.
- Current unlawful use of or addiction to a controlled substance.
- A court finding of mental incompetence or a commitment to a mental institution.
- A dishonorable discharge from the military.
- Fugitive status.
Additional categories cover certain immigration statuses and people who have renounced U.S. citizenship.2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts If any of these apply to you, buying or possessing an AK is a federal felony regardless of state law.
Buying an AK-Style Rifle
Every purchase from a Federal Firearms Licensee triggers a background check through the FBI’s National Instant Criminal Background Check System. You fill out ATF Form 4473, the dealer runs NICS, and the system responds with proceed, denied, or delayed. Most checks clear within minutes.3Federal Bureau of Investigation. Firearms Checks (NICS) A denial can be appealed, but the burden is on you to show the record is wrong.
The federal minimum age is 18 for a rifle bought from a dealer and 21 for a handgun, which includes AK-style pistols.2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Some states set higher floors, so check local rules first.
Private sales between two residents of the same state do not require a federal background check under the Gun Control Act.2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts A growing number of states now require even private transfers to go through a licensed dealer. Selling to someone you know or have reason to believe is a prohibited person is a federal crime either way.
Fully Automatic AK-47s
A true select-fire AK-47, the kind that fires more than one round per trigger pull, is legal to own but expensive and tightly controlled. Two laws create the bottleneck. The National Firearms Act of 1934 set up the registration and tax framework for machine guns, and the Firearm Owners Protection Act of 1986 permanently closed the civilian registry to any machine gun made after May 19, 1986.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act Only machine guns already registered before that date can be transferred to private citizens.
To buy one, you file ATF Form 4, pay a $200 transfer tax, submit fingerprints and photographs, and notify your local chief law enforcement officer.4Bureau of Alcohol, Tobacco, Firearms and Explosives. National Firearms Act Processing has sped up considerably. As of early 2026, the ATF reports Form 4 eFile approvals averaging around 10 days for individuals and 26 days for trusts.5Bureau of Alcohol, Tobacco, Firearms and Explosives. Current Processing Times
Price is the real barrier. Because the supply is permanently fixed and demand keeps climbing, pre-1986 fully automatic AK-pattern rifles routinely sell for $45,000 to $55,000 or more.
Possessing an unregistered machine gun carries serious penalties. Under the NFA, conviction can bring up to ten years in prison and a fine of up to $10,000.6Office of the Law Revision Counsel. 26 U.S. Code 5871 – Penalties Prosecutors can also charge under 18 U.S.C. § 922(o) and § 924, with fines for individuals reaching $250,000. If the machine gun is used in a crime of violence or drug trafficking offense, federal sentencing includes a mandatory minimum of 30 years.7Office of the Law Revision Counsel. 18 U.S. Code 924 – Penalties
AK Pistols and Short-Barreled Rifles
AK-platform firearms built with a barrel under 16 inches and no shoulder stock are classified as pistols, not rifles, and fall outside the NFA’s short-barreled rifle rules. Many of these are sold with “stabilizing braces” that resemble a shoulder stock in appearance and function.
In 2023 the ATF issued a rule that would have reclassified many braced pistols as short-barreled rifles subject to NFA registration. Federal courts blocked enforcement, and in June 2024 a district court vacated the rule entirely. As of May 2026, the ATF is formally proposing to rescind it and restore the prior definitions.8Federal Register. Removing Factoring Criteria for Firearms With Attached Stabilizing Braces The practical effect is that braced AK pistols are treated as pistols at the federal level.
If you want to add a shoulder stock to an AK pistol, turning it into a short-barreled rifle, you must file ATF Form 1, pay the $200 making tax, notify your chief law enforcement officer, and wait for ATF approval before making the modification.9Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Make and Register NFA Firearm (Form 1) Building an SBR without approval is a federal felony. Several states ban short-barreled rifles entirely, so a federal tax stamp does not guarantee the firearm is legal where you live.
Imported Rifles and the Parts-Count Rule
Most AK designs trace back to foreign manufacturers, which brings importation rules into play. Under 18 U.S.C. § 922(r), a semi-automatic rifle cannot be assembled from imported parts if the resulting firearm matches a type that cannot be imported for lacking a “sporting purpose.”2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Under the ATF’s implementing regulation at 27 CFR § 478.39, a completed rifle may not contain more than 10 imported parts from a list of 20 specific components.10Bureau of Alcohol, Tobacco, Firearms and Explosives. 27 CFR 478.39 – Assembly of Semiautomatic Rifles or Shotguns
Importers and home builders satisfy the rule by swapping in U.S.-made components, most often the trigger group, muzzle device, pistol grip, and stock furniture. This mainly matters if you are building from a parts kit or buying a domestically assembled import; documenting the origin of each component is essential, because a parts-count violation can bring felony charges and seizure of the firearm.
State Bans and Magazine Limits
Roughly a dozen states and Washington, D.C., have assault weapons laws that restrict or ban AK-style rifles. The statutes vary. Some list prohibited models by name. Others apply a features test, banning any semi-auto rifle that combines a detachable magazine with one or more military-style features such as a pistol grip, folding or telescoping stock, flash suppressor, or forward grip. A few states bar only new sales and manufacture while allowing continued possession of existing firearms.
In features-test states, owners sometimes reconfigure their rifles to comply. A “featureless” build swaps the standard pistol grip for a fin-style grip that keeps the thumb off the top of the stock, uses a fixed stock, and replaces any flash hider with a muzzle brake. A “fixed magazine” build locks the magazine so it cannot be removed without partially disassembling the action, which preserves the standard ergonomic features. Both approaches have real handling trade-offs, and the compliance details differ by state.
Standard AK magazines hold 30 rounds, which creates a separate problem in the 14 states that as of early 2026 restrict magazine capacity. Most set the limit at 10 rounds, though a few allow slightly more. Reduced-capacity magazines are required in those jurisdictions, and possessing a 30-round magazine can be charged on its own even if the rifle itself is legal.
State assault weapons offenses are typically felonies, with sentences ranging from probation to multiple years in state prison depending on the state and the circumstances. Magazine violations often stack on top, and seized firearms are almost always forfeited.
Traveling Between States
A rifle that is legal at home may be a felony one state over. Federal law provides a limited safe harbor for interstate transport: if you can legally possess the firearm in both your point of origin and your destination, you may pass through restrictive states as long as the gun is unloaded and neither the firearm nor the ammunition is readily accessible from the passenger compartment. In vehicles without a separate trunk, both must be in a locked container other than the glove box or console.11Office of the Law Revision Counsel. 18 U.S. Code 926A – Interstate Transportation of Firearms
The protection covers transportation, not extended stops. Overnight stays or side trips in a state that bans your rifle put you on much shakier ground, and litigating a federal preemption argument from a jail cell is not a position anyone wants to be in.
Registered NFA firearms add another layer. Before moving a machine gun or short-barreled rifle across state lines, the registered owner must file ATF Form 5320.20 and receive written approval covering the time frame and destination.12Bureau of Alcohol, Tobacco, Firearms and Explosives. Application to Transport Interstate or to Temporarily Export Certain NFA Firearms Moving a registered machine gun without that approval is itself a federal offense.
