When federal prosecutors add a gun charge in Washington, the stakes can climb fast. A case that was already serious may suddenly carry mandatory incarceration, consecutive sentencing, property forfeiture, and permanent limits on firearm ownership. These prosecutions are often built by the ATF and the U.S. Attorney’s Office alongside allegations of federal drug crimes, conspiracy, robbery, or violent conduct.
You can face a federal gun charge without ever pulling a trigger. The government may focus instead on where the firearm was found, who could control it, how it was purchased, whether registration rules were followed, or what was written on a purchase form. Once attached to another case in Washington, a firearm count can become the part that drives the sentence.

When federal agents and prosecutors set their sights on someone in Washington, Combs Waterkotte is prepared to push back. Our federal criminal defense team serving Washington looks beyond the fact that a gun was found and asks the questions that can change a case: Who knew it was there? Who could control it? Was the search lawful? Can the government actually connect it to the alleged crime?
You should not wait for an indictment to start protecting yourself. If ATF agents have contacted you, you have received a federal target letter, or you believe an arrest or charge is on the horizon, call (314) 900-HELP or contact Combs Waterkotte online.

When Does a Firearm Case Become Federal?
Not every federal gun case begins with federal agents at the door. Many start as ordinary state arrests before a task force or U.S. Attorney’s Office steps in. That can happen when the alleged conduct fits a federal offense under the Gun Control Act, the National Firearms Act, or another federal firearms law. Once that happens, the case moves onto a very different playing field.
Federal prosecutors may become involved if:
- The firearm crossed state lines or otherwise moved through interstate commerce
- The person accused falls within a federally prohibited category
- The gun was allegedly connected to drug trafficking or a violent offense
- Investigators suspect straw purchases, illegal dealing, smuggling, or trafficking
- The weapon is regulated under federal law, such as a machine gun, suppressor, short-barreled firearm, or destructive device
- The serial number was allegedly altered, removed, or obliterated
- The conduct occurred on federal land or drew the attention of a federal task force
- Agents claim the firearm was tied to a gang, criminal organization, or broader conspiracy
The first sign of trouble may come late in the investigation. Agents may already have traced the gun, interviewed witnesses, reviewed online activity, pulled phone data, and gathered physical evidence before the accused knows federal prosecutors are involved.
Under Federal Gun Investigation in Washington? Take These Steps
Federal investigations usually develop quietly. If agents have reached out, searched your property, questioned someone close to you, or asked you to “clear a few things up,” assume the case is already moving. You should treat every conversation and decision as part of the defense.
Take the following steps as soon as you suspect a federal firearms investigation:
- Do not speak with federal agents without a federal firearms attorney in Washington. 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 in Washington immediately. Early representation can protect your rights, prevent unnecessary mistakes, and allow your attorney to communicate with investigators on your behalf.
Federal Firearm Offenses Charged in Washington
Felon in Possession of a Firearm
A person may face a federal gun charge based on their legal status rather than how the firearm was allegedly used. Under 18 U.S.C. § 922(g), firearm and ammunition possession is prohibited for several categories of restricted persons.
The federal prohibition may apply to:
- Individuals with certain felony or felony-level convictions
- People accused of fleeing to avoid prosecution
- People considered unlawful users of illegal drugs or other controlled substances
- Individuals covered by certain domestic protection orders
- People convicted of qualifying misdemeanor domestic violence crimes
- Some noncitizens and former service members who received dishonorable discharges
Prosecutors generally must establish that the accused knowingly possessed the firearm or ammunition and knew of the status that made possession unlawful.
The government may try to prove possession in either of two ways:
- Actual possession: The accused allegedly carried the firearm or had it physically on their body.
- Constructive possession: The accused allegedly knew where the gun was and had both the power and intent to exercise control over it.
Constructive possession can become the fault line of the case when a firearm is recovered from a place multiple people could access, such as a shared residence, borrowed car, hotel room, or common storage area.
Federal Gun Enhancements for Drug and Violent Offenses
A firearm allegation can become its own criminal count when it is tied to certain drug or violent offenses. Under 18 U.S.C. § 924(c), prosecutors may charge a person with using or carrying a gun during a qualifying offense or possessing one to advance that offense.
The statute carries mandatory minimum prison terms that generally run back-to-back with the sentence imposed for the related offense:
- Five years or more when a firearm was possessed, used, or carried
- Seven years or more when the weapon was allegedly displayed or brandished
- Ten years or more when the gun was fired
- Substantially greater exposure for specially regulated firearms and devices
The prosecution may describe a firearm as a tool of the alleged offense even when it stayed hidden or untouched. That argument commonly relies on its location near:
- Controlled substances
- Large amounts of currency
- Baggies, scales, or packaging supplies
- Ledgers, customer lists, or distribution records
- Other items prosecutors associate with drug sales
The key fight may be over the connection between the person, the firearm, and the underlying offense. Defense counsel can challenge whether the accused knew the gun was there, had the ability to reach or control it, or possessed it to advance any criminal activity.
False Actual-Buyer Allegations
A lawful-looking retail purchase can become a federal case when agents believe the named buyer was only standing in for another person. These straw purchase investigations often center on what the buyer intended and what they reported on Form 4473. Prosecutors may also rely on 18 U.S.C. § 932.
Questions that may determine whether the transaction was lawful include:
- 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
Agents may build the case from messages, bank or payment-app records, dealer paperwork, surveillance video, and whatever the purchaser or recipient said during interviews.
Illegal Gun 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.
A trafficking investigation may involve guns that were:
- Supplying guns to prohibited recipients
- Moving firearms across state lines as part of a broader operation
- Providing weapons for alleged drug trafficking or violent conduct
- Using several purchasers to avoid detection
- Operating what prosecutors view as an unlicensed resale business
- Sending firearms outside the United States unlawfully
When Private Gun Sales Become Federal Charges
An individual may lawfully make some private firearm sales without becoming a licensed dealer. Problems arise when federal agents believe the person crossed from disposing of personal property into running a gun business without the required federal firearms license.
Prosecutors may examine:
- The volume and regularity of transactions
- How long the accused kept each firearm before selling it
- Whether buyers were solicited through websites, forums, or personal networks
- Cash, electronic payments, and customer conversations
- Whether the sales produced or were intended to produce profit
- Evidence of inventory, repeat customers, or ongoing operations
False Information Given to a Licensed Gun Dealer
A knowingly false answer given during a firearm transaction can lead to federal charges under 18 U.S.C. § 922(a)(6) if the information mattered to whether the dealer could lawfully complete the sale.
Federal investigators may focus on statements about:
- The actual transferee or intended recipient
- Felony or other prohibiting convictions
- Unlawful drug use
- Domestic violence history or court orders
- Nationality and immigration status
- Personal identification and residence information
The government must do more than point to an inaccurate box on a form. The defense may dispute whether the response was truly false, whether the accused understood it was wrong, or whether it made any legal difference to the sale.
Possession of a Firearm With an Altered or Obliterated Serial Number
A damaged or missing serial number can create separate federal exposure. Under 27 CFR § 478.34, the government may prosecute certain knowing possession, transportation, or receipt of a firearm with altered identifying marks.
The serial number itself is only part of the case. Other issues include:
- How obvious the serial number damage was
- Whether the markings remained readable
- Whether forensic specialists can restore or identify the number
- Whose fingerprints, DNA, or other evidence connect the weapon to
The alleged alteration can affect more than guilt or innocence. It may also support an enhancement when the sentencing guidelines are calculated.
Homemade and Privately Assembled Firearms
The label “ghost gun” can make a case sound simpler than it is. A privately assembled firearm may be lawful in some circumstances, while its possession, manufacture, sale, or markings may create federal exposure in others.
The government may try to build its case around:
- Possession by a prohibited person
- The number and type of firearms produced
- Messages or payments showing planned sales
- Whether the accused acted as an unlicensed manufacturer or dealer
- The absence of markings required under federal law
- The use or presence of the firearm during another alleged offense
Unserialized firearms may bring an additional sentencing problem, particularly when the federal guidelines call for an enhancement.
Federal National Firearms Act Charges
The National Firearms Act imposes registration, taxation, manufacturing, and transfer requirements on certain weapons and devices.
NFA-regulated firearms include:
- Machine guns
- Shortened rifles
- Shortened shotguns
- Suppressors, including devices commonly called silencers
- Certain bombs, explosives, and destructive devices
- Unusual or concealed weapons classified as “any other weapon”
The issue may be registration, how the weapon was built, how it changed hands, or whether identifying marks were removed. These are felony-level allegations, and a conviction may carry up to 10 years of imprisonment along with fines and loss of the weapon.
Federal Firearm Sentences in Washington
The statute provides only part of the sentencing picture. A person’s record, the characteristics of the weapon, the presence of drugs or violence, mandatory minimum laws, and the United States Sentencing Guidelines can all move the potential punishment higher or lower.
| Federal Gun Offense | Potential Penalty |
|---|---|
| Possessing a gun or ammunition while federally prohibited | Up to 15 years in many cases, with a 15-year mandatory floor when ACCA applies |
| A § 924(c) firearm charge tied to drug trafficking or a qualifying violent offense | At least five years, increased to seven for brandishing or 10 for discharge; the sentence usually runs after the underlying sentence |
| Straw purchasing under 18 U.S.C. § 932 | A maximum of 15 years in ordinary cases, potentially rising to 25 years when the weapon is believed destined for certain serious offenses |
| Federal gun trafficking under § 933 | Up to 15 years in federal prison |
| Engaging in the business of firearm sales without federal licensing | Typically punishable by up to five years |
| False statements on firearm purchase paperwork | Up to 10 years in federal prison |
| Possessing a firearm with an altered or obliterated serial number under § 922(k) | A possible five-year sentence plus additional guideline consequences |
| Offenses involving unregistered or unlawfully transferred NFA weapons | Up to 10 years in federal prison, fines, and firearm forfeiture |
| Unlawful possession, receipt, or transfer of a machine gun | Frequently punishable by as much as 10 years, although a connection to drug trafficking or violence can drive the sentence much higher |
A statutory maximum does not tell you exactly what sentence the court will impose. Federal judges also consider the offense conduct, firearm characteristics, criminal history, mandatory sentencing laws, and the advisory range produced by the United States Sentencing Guidelines.
Prison is only one possible consequence of a federal firearm conviction. A sentence may also involve:
- Fines and court-ordered financial obligations
- Post-release supervision with strict federal conditions
- Forfeiture of the firearm and other property allegedly connected to the offense
- The loss of federal firearm rights
- Difficulty finding employment, securing housing, or keeping a professional license
- Serious immigration consequences, including possible deportation exposure
A federal sentence is not typically cut short through parole. Although some prisoners can earn good-conduct credit, federal incarceration generally means serving the great majority of the term imposed.
Federal Gun Charges and the ACCA
For some defendants, the biggest battle is not whether § 922(g) applies, but whether the government can trigger the ACCA. That designation replaces the ordinary sentencing range with a mandatory minimum term of 15 years.
ACCA may apply to a person convicted under 18 U.S.C. § 922(g) who has three qualifying prior convictions involving violent felonies, serious drug crimes, or some combination of the two, so long as the offenses occurred on different occasions.
A conviction that sounds violent in ordinary conversation may still fail to qualify under federal law. These disputes often require a close reading of statutes, old court documents, and changing ACCA precedent.
Potential ACCA challenges include:
- The government’s classification of the prior offense
- Ambiguities in charging documents, plea agreements, or judgments
- Whether multiple convictions arose from a single criminal episode
- The present legal status of an old conviction
- Restoration of rights under state or federal law
When three qualifying convictions are required, knocking out one may knock out the entire 15-year mandatory minimum. That can completely reshape the sentencing landscape.
Federal Sentencing Enhancements in Washington Firearm Cases
Even when no statutory mandatory minimum applies, the United States Sentencing Guidelines may significantly increase the recommended sentencing range.
Federal prosecutors may seek sentencing increases based on allegations such as:
- Large numbers of firearms
- Stolen weapons
- Altered or obliterated serial numbers
- Trafficking-related conduct
- Machine guns, silencers, destructive devices, or similar regulated weapons
- Firearm possession connected to another felony
- Reckless endangerment while fleeing
- Acting as an organizer or leader
- Obstruction of justice allegations
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.
Do You Need a Federal Gun Charges Lawyer?
The best time to hire a federal gun charges attorney is usually before formal charges are filed. If you believe federal agents are investigating you, waiting for an indictment may cost valuable opportunities.
You should take the situation seriously if:
- 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
An early defense strategy is often very different from a trial strategy. Before an indictment, counsel may be able to communicate with federal agents, protect you from making damaging statements, investigate the facts, analyze search and seizure issues, and provide prosecutors with information that could influence charging decisions.
