Federal Gun Charges Lawyer

Verified Content

Posted by Christopher Combs on July 22, 2026

Federal gun charges can turn an already serious criminal case into one carrying mandatory prison time, consecutive sentences, firearm forfeiture, and lasting restrictions on your rights. These cases are commonly investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and prosecuted by the U.S. Attorney’s Office, often alongside federal drug trafficking, conspiracy, robbery, or violent crime allegations.

The government does not necessarily need evidence that you used a gun. Possessing a firearm, having access to one, buying one for someone else, providing false information during a purchase, or possessing certain unregistered weapons may be enough to support federal charges. A firearm allegation can also add years or decades to the sentence imposed for another offense.

    What Makes a Gun Charge Federal?

    Most firearm cases begin under state law. However, a case may enter the federal system when the alleged conduct violates the federal Gun Control Act, the National Firearms Act, or another federal statute. State and local authorities may also refer a case to federal prosecutors when they believe federal penalties will be more severe.

    Federal jurisdiction may arise when:

    • A firearm traveled through interstate or foreign commerce
    • The accused is legally prohibited from possessing firearms or ammunition
    • A firearm was allegedly used during a drug trafficking crime or crime of violence
    • The case involves firearm trafficking, smuggling, straw purchasing, or unlicensed dealing
    • The weapon is a machine gun, silencer, short-barreled rifle, short-barreled shotgun, or destructive device
    • The firearm had an altered or removed serial number
    • The alleged conduct occurred on federal property or involved a federal investigation
    • Federal agents believe the firearm is connected to organized criminal activity

    By the time a person learns about the investigation, agents may already have collected surveillance footage, phone records, social media posts, witness statements, firearm traces, and forensic evidence.



    What Should You Do If You’re Under Investigation for a Federal Gun Crime?

    You do not have to be arrested to need a federal defense attorney. By the time ATF agents contact you, execute a search warrant, or ask to speak with you, they may have already spent weeks or months building their case. What you do next can significantly affect the outcome.

    If you believe you are under investigation for a federal firearm offense:

    • Do not speak with federal agents without a federal firearms attorney attorney. You have the right to remain silent. Even truthful statements can be misunderstood or used against you later.
    • Do not consent to additional searches. If agents have a warrant, do not interfere, but you are not required to give permission for searches beyond the warrant’s scope.
    • Preserve potential evidence. Keep text messages, emails, receipts, firearm purchase records, photographs, and other documents that may help explain what happened. Do not delete or destroy anything.
    • Avoid discussing the investigation with others. Phone calls, text messages, emails, and social media posts can become evidence. Conversations with friends, family members, or potential witnesses may also be scrutinized.
    • Contact a federal criminal defense lawyer immediately. Early representation can protect your rights, prevent unnecessary mistakes, and allow your attorney to communicate with investigators on your behalf.


    Common Federal Gun Charges


    Felon in Possession of a Firearm

    Under 18 U.S.C. § 922(g), several categories of people are prohibited from possessing firearms or ammunition.

    Prohibited persons may include:

    • People convicted of crimes punishable by more than one year in prison
    • Fugitives from justice
    • Unlawful users of controlled substances
    • Certain people subject to domestic violence restraining orders
    • People convicted of qualifying domestic violence offenses
    • Certain noncitizens and people dishonorably discharged from the military

    Prosecutors generally must establish that the accused knowingly possessed the firearm or ammunition and knew of the status that made possession unlawful.

    Possession may be:

    • Actual possession: The firearm was allegedly found directly on the person.
    • Constructive possession: The person allegedly knew the firearm was present and had the ability and intention to control it.

    Constructive possession is often disputed when a gun is found in a shared home, borrowed vehicle, hotel room, or another location used by several people.

    Possessing a Firearm During a Drug Trafficking Crime or Crime of Violence

    18 U.S.C. § 924(c) makes it a separate federal offense to use or carry a firearm during and in relation to a qualifying crime of violence or drug trafficking crime, or to possess one in furtherance of such a crime.

    The mandatory minimum sentence generally must be served consecutively to the sentence for the underlying offense:

    • At least five years for possessing, using, or carrying a firearm
    • At least seven years if the firearm was brandished
    • At least 10 years if the firearm was discharged
    • Higher minimums when machine guns, silencers, or destructive devices are involved

    The firearm does not have to be fired. Prosecutors may argue that a gun advanced or protected the alleged crime because it was found near:

    • Illegal drugs
    • Cash
    • Packaging materials
    • Distribution records
    • Other alleged evidence of trafficking

    The defense may challenge whether the accused knew about the firearm, could access it, or possessed it for any reason connected to the alleged offense.

    Straw Purchasing a Firearm

    A straw purchase generally occurs when one person buys a firearm for someone else while falsely claiming to be the actual buyer. Charges may arise from statements made on ATF Form 4473 or under 18 U.S.C. § 932.

    These cases may depend on:

    • Who paid for the firearm
    • Who selected the firearm
    • The buyer’s intent at the time of purchase
    • Whether the firearm was intended as a lawful gift
    • What the purchaser knew about the eventual recipient

    Potential evidence may include text messages, payment records, store surveillance, purchase forms, and statements made to investigators.

    Firearms Trafficking

    18 U.S.C. § 933 prohibits certain transfers, transportation, or receipt of firearms when the accused knows or has reasonable cause to believe the firearm will be used, possessed, or transferred unlawfully.

    Firearms trafficking allegations may involve weapons that were:

    • Purchased for prohibited persons
    • Moved across state or international borders
    • Sold to people involved in drug trafficking or violent crime
    • Acquired through multiple straw purchasers
    • Resold without a required license
    • Smuggled into another country

    Dealing Firearms Without a Federal License

    Federal law generally requires a person who is engaged in the business of dealing firearms to obtain a federal firearms license. An occasional private sale does not automatically make someone a firearms dealer.

    Prosecutors may examine:

    • The number and frequency of sales
    • How quickly firearms were resold after purchase
    • Whether the accused advertised firearms for sale
    • Customer communications and payment records
    • Whether transactions were intended to produce a profit
    • Whether the accused maintained firearm inventory

    False Statements During a Firearm Purchase

    Under 18 U.S.C. § 922(a)(6), it is illegal to knowingly make a false statement to a federally licensed firearms dealer when that statement is material to the legality of the sale.

    Alleged false statements may involve:

    • The identity of the actual purchaser
    • A prior criminal conviction
    • Controlled substance use
    • A domestic violence conviction or restraining order
    • Immigration or citizenship status
    • Residence or identification information

    The defense may challenge whether the answer was actually false, whether the accused knowingly provided incorrect information, and whether the statement affected the legality of the transaction.

    Possession of a Firearm With an Altered or Obliterated Serial Number

    Under 27 CFRF § 478.34 federal law prohibits knowingly transporting, receiving, or possessing certain firearms with serial numbers that have been removed, altered, or obliterated.

    Important questions may include:

    • Whether the accused knew the serial number had been altered
    • Whether the markings meet the statutory definition
    • Whether forensic testing can recover the original number
    • Whether the government can connect the accused to the firearm

    An altered serial number may also increase the recommended sentence under the federal sentencing guidelines.

    Privately Made Firearms and “Ghost Guns”

    A privately made firearm is not automatically illegal simply because an individual assembled it. Criminal exposure may arise depending on:

    • Who possessed the firearm
    • How it was manufactured
    • Whether it was transferred or sold
    • Whether the accused was acting as a firearms manufacturer or dealer
    • Whether required markings were missing
    • Whether the firearm was connected to other illegal conduct

    Sentencing enhancements may also apply in some cases involving firearms without required serial numbers.

    National Firearms Act Violations

    The National Firearms Act imposes registration, taxation, manufacturing, and transfer requirements on certain weapons and devices.

    NFA-regulated firearms include:

    • Machine guns
    • Short-barreled rifles
    • Short-barreled shotguns
    • Silencers and suppressors
    • Destructive devices
    • Certain weapons classified as “any other weapon”

    Charges may involve possessing an unregistered weapon, illegally manufacturing or transferring one, or possessing a firearm with required identifying information removed. A conviction can carry up to 10 years in federal prison, fines, and forfeiture.



    Penalties for Federal Gun Charges

    Federal firearm penalties depend on the specific statute, the type of weapon, the accused’s criminal history, whether another offense was involved, and how the United States Sentencing Guidelines apply.

    Federal Firearm Charge Potential Penalty
    Possession by a prohibited person under 18 U.S.C. § 922(g) Generally up to 15 years in federal prison; qualifying Armed Career Criminal Act cases carry a mandatory minimum of 15 years
    Possessing, carrying, or using a firearm during a drug trafficking crime or crime of violence under § 924(c) Mandatory minimum of five years, seven years if brandished, or 10 years if discharged, generally served consecutively
    Straw purchasing under 18 U.S.C. § 932 Up to 15 years, or up to 25 years when the buyer knows or has reason to believe the firearm will be used to commit certain serious crimes
    Firearms trafficking under 18 U.S.C. § 933 Up to 15 years in federal prison
    Dealing firearms without a required federal license Generally up to five years in federal prison
    Making false statements during a firearm purchase under § 922(a)(6) Up to 10 years in federal prison
    Possessing a firearm with an altered or obliterated serial number under § 922(k) Generally up to five years in federal prison, with possible sentencing enhancements
    National Firearms Act violations Up to 10 years in federal prison, fines, and firearm forfeiture
    Illegal machine gun possession or transfer Often up to 10 years, with substantially greater exposure when connected to a drug trafficking crime or crime of violence


    These are general statutory penalties. The actual sentencing range may depend on the specific charge, the type and number of firearms involved, the defendant’s criminal history, applicable mandatory minimums, and the United States Sentencing Guidelines.

    Federal sentences may also include:

    The federal system does not offer traditional parole. While eligible prisoners may earn limited good-conduct credit, a federal sentence usually requires serving most of the term imposed by the court.

    The Armed Career Criminal Act

    The Armed Career Criminal Act, commonly called the ACCA, can transform a felon-in-possession case into one carrying a mandatory minimum sentence of 15 years.

    The enhancement may apply when a person convicted under 18 U.S.C. § 922(g) has three qualifying prior convictions for violent felonies, serious drug offenses, or both, committed on occasions different from one another.

    Whether a prior conviction qualifies is frequently disputed. Courts must analyze the statute underlying the earlier conviction, the available court records, and evolving federal case law. The label placed on a state offense does not always determine whether it counts under the ACCA.

    A federal defense lawyer may challenge:

    • Whether the prior offense meets the federal definition
    • Whether the conviction records establish the required elements
    • Whether multiple offenses occurred on different occasions
    • Whether a conviction was vacated, expunged, or otherwise invalid
    • Whether the accused’s civil rights had been restored

    Because the ACCA creates a mandatory minimum sentence, resolving even one disputed prior conviction can make an enormous difference.

    Federal Sentencing Enhancements in Firearm Cases

    Even when no statutory mandatory minimum applies, the United States Sentencing Guidelines may significantly increase the recommended sentencing range.

    Possible enhancements include allegations involving:

    • Multiple firearms
    • Stolen firearms
    • Firearms with altered, obliterated, or missing serial numbers
    • Trafficking or transferring firearms to prohibited persons
    • Possession of a machine gun, silencer, destructive device, or other NFA weapon
    • Possession or use of a firearm in connection with another felony
    • Reckless endangerment during flight
    • A leadership or organizational role
    • Obstruction of justice

    The sentencing guidelines are advisory, but federal judges must calculate and consider them. Defense counsel can challenge enhancements, present mitigating evidence, seek departures or variances, and argue that the recommended range is greater than necessary.

    When Should You Hire a Federal Gun Charges Lawyer?

    You should contact a federal defense lawyer as soon as you believe an investigation may involve you. You do not need to wait for an arrest or indictment.

    Warning signs include:

    • ATF, FBI, DEA, or task force agents attempt to question you
    • Agents execute a search warrant at your home or business
    • Someone close to you receives a subpoena
    • Law enforcement seizes firearms, phones, computers, or records
    • You receive a federal target letter
    • A codefendant or alleged associate is arrested
    • A state firearm case is dismissed or delayed without explanation
    • You learn that federal prosecutors are reviewing your case

    Early representation may allow an attorney to communicate with investigators, prevent an unprotected interview, preserve evidence, challenge a search, evaluate possible exposure, and present information before prosecutors make charging decisions.
