Unforeseen Criminal Charges for Selling a Firearm in Arizona

Selling a firearm in Arizona can seem simple, especially since the state is widely recognized for its strong protections on firearm ownership. Many residents assume they can freely sell guns in private transactions without concern. However, misunderstanding or overlooking certain firearm laws can lead to unforeseen criminal charges. Even a casual sale to a friend, coworker, or neighbor may expose someone to felony charges under Arizona law or federal law.
Arizona statutes like ARS 13-3102 (Misconduct Involving Weapons) and ARS 13-3107 (Unlawful Discharge of Firearms) create boundaries for lawful firearm sales and use. Violating these statutes — intentionally or not — can mean harsh penalties, a lasting criminal record, and years in prison.

Firearm Laws That Govern Sales in the State of Arizona
Although Arizona allows broad firearm ownership rights, it does not give residents free rein to sell guns without restrictions. Both state law and federal law regulate how and when a person can sell or transfer a gun.
Key points under ARS 13-3102 (Arizona’s Misconduct Involving Weapons law):
- It is unlawful to knowingly sell or transfer a firearm to a prohibited possessor.
- Private sales between Arizona residents do not require background checks, but this does not excuse sellers if the buyer is later found to be a prohibited possessor.
- While Arizona law allows the private sale of firearms to individuals 18 and older, federal law prohibits licensed dealers from selling handguns to individuals under 21.
Key points under federal firearm laws (18 U.S.C. § 922):
- Firearm dealers licensed by the ATF must conduct background checks and keep detailed sales records.
- It is a federal criminal act to sell firearms without a license across state lines.
- Selling to someone under indictment for, or convicted of, a felony is unlawful under federal law.
Although Arizona allows private firearm transactions, the overlap between state and federal rules is where problems often occur.

Common Situations That Lead to Unlawful Firearm Sales
Many Arizonans facing criminal charges for firearm sales never intended to break the law. Still, the state of Arizona can prosecute sellers under circumstances such as:
- Selling to a prohibited possessor, even unknowingly
- Private sales without background checks where the buyer later commits a crime
- Cross-state firearm sales, which violate federal firearm statutes unless completed through a licensed dealer
- Selling to minors, which is a felony charge unless parental consent is given
- Improper record-keeping by licensed gun dealers
Example: A Phoenix resident sells a firearm in Arizona to an acquaintance who later uses the gun in a robbery. Prosecutors may argue that the seller committed an unlawful sale, exposing them to a felony conviction, despite no intent to commit a crime.
Who Is a Prohibited Possessor Under Arizona Law?
Under ARS 13-3101(A)(7), the term “prohibited possessor” includes:
- Anyone convicted of a felony in Arizona or another state, if civil rights are not restored
- Individuals currently on probation or parole for a felony conviction
- People confined to a correctional facility
- Individuals found incompetent to stand trial or guilty except insane
- Those subject to an active order of protection in domestic violence cases
- Undocumented immigrants under federal firearm laws
Selling to any of these individuals, knowingly or unknowingly, can result in severe penalties. This is why consulting a gun attorney or gun crime lawyer before engaging in questionable sales is critical.

Federal Firearm Sale Laws vs. Arizona State Law
Although Arizona allows more flexibility, federal law imposes strict rules. The differences often catch sellers off guard.
- Arizona law allows private sales without background checks
- Federal law requires all interstate transfers to go through a licensed dealer
- Arizona does not require firearm registration, while federal authorities can still pursue unlicensed sales
- Arizona allows adults 18 or older to possess a firearm, but federal law restricts handgun sales from dealers to those 21 and older
This confusion frequently leads to criminal cases where an otherwise legal transaction under state law becomes a federal criminal violation.
Penalties for Unlawful Firearm Sales
Selling firearms without following state or federal firearm laws can result in felony charges, large fines, and long-term damage to a person’s criminal record.
Arizona Penalties (ARS 13-3102)
- Selling to a prohibited possessor: Class 6 felony (up to 2 years in prison)
- Selling to a minor without consent: Class 6 felony
- Supplying firearms for criminal acts: Class 3 felony (up to 8.75 years in prison)
Federal Penalties (18 U.S.C. § 922)
- Unlawful firearm sales: Up to 10 years in prison
- Selling without a license: Up to 5 years in prison
- Interstate transfers without a dealer: Up to 5 years in prison
Penalties Chart
Offense | Arizona Penalty | Federal Penalty |
Selling to a Prohibited Possessor | Class 6 Felony in Arizona | Up to 10 years in prison |
Selling to a Minor | Class 6 Felony | Possible federal charges |
Unlicensed Firearm Sales Across State Lines | Not directly addressed | Up to 5 years in prison |
ARS 13-3107 and the Unlawful Discharge of Firearms
ARS 13-3107, often called Shannon’s Law, makes it unlawful to discharge a firearm within or into the limits of a municipality in Arizona.
Key facts:
- Discharging a firearm in public or firing a gun into the air is a Class 6 felony
- Even if no one is hurt and the discharge occurred due to criminal negligence, the law treats it seriously
- Those charged with unlawful discharge face a permanent mark on their criminal record
This law often affects those who fire a gun during celebrations, unaware that firing into the air is unlawful. Even if the discharge occurred during a vacation in Arizona, penalties apply.
Defense Strategies From an Experienced Criminal Defense Attorney
When facing criminal charges for firearm sales or unlawful discharge, working with a skilled criminal defense attorney is critical. Strategies that may protect your rights include:
- Lack of knowledge – Arguing the seller had no knowledge the buyer was a prohibited possessor
- Unlawful search and seizure – Challenging how evidence was obtained
- Entrapment – If law enforcement pressured the defendant into making an unlawful sale
- Procedural errors – Mistakes by the prosecutor or law enforcement can help get a case dismissed
- Mitigate penalties – Showing the discharge occurred unintentionally or with no criminal negligence
- Strong defense in court – Using inconsistencies in testimony or weak evidence to pursue reduced charges or dismissal
An experienced criminal defense attorney like Josh Kolsrud understands both state and federal firearm laws and knows how to fight for a favorable outcome.
Real-World Examples of Firearm Sales Leading to Felony Charges
Phoenix Example
A man sells a firearm in Arizona to a neighbor who is secretly a convicted felon. When the gun is later recovered in a crime, the seller is accused of an unlawful firearm sale.
Tempe Example
A college student sells a handgun to a 19-year-old classmate. Although Arizona allows adults over 18 to possess a firearm, federal law restricts handgun sales under 21. This results in federal criminal charges.
Mesa Example
During a holiday celebration, a resident fires a gun into the air. Police later trace the incident and charge the resident under ARS 13-3107, leading to a Class 6 felony charge for unlawful discharge of firearms.
