Federal gun prosecutions in Washington can bring a second wave of exposure to an existing criminal case. Beyond the underlying accusation, you may face additional prison time, sentences that must run back-to-back, seizure of firearms, and restrictions that follow you for years. The ATF and federal prosecutors often use firearm charges to strengthen cases involving drug trafficking, conspiracy, robbery, and violent offenses.
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?
Maybe agents have already searched your property. Maybe someone close to you has been questioned. Maybe a target letter just landed in your hands. Whatever tipped you off, do not ignore it. Reach out to Combs Waterkotte or call (314) 900-HELP before speaking with investigators or making a move that cannot be undone.

What Makes a Gun Charge 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.
Common reasons a firearm case enters federal court include:
- The government claims the firearm crossed state or national boundaries
- The accused allegedly could not lawfully possess a firearm
- The gun was found during a drug, robbery, conspiracy, or violent crime investigation
- The case involves suspected trafficking, unlicensed sales, straw purchasing, or smuggling
- The weapon is a machine gun, silencer, short-barreled rifle, short-barreled shotgun, or destructive device
- Identifying marks or serial numbers were allegedly removed or changed
- The alleged offense took place within federal jurisdiction
- Federal agents connect the firearm to a larger criminal operation
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 to Do During a Federal Firearms Investigation in Washington
An arrest is not the starting line of a federal gun case. ATF agents may already have reviewed records, interviewed witnesses, traced firearms, and gathered digital evidence before they ever contact you. The decisions you make at that point can either protect your position or hand the government more ammunition.
If you believe you are under investigation for a federal firearm offense:
- Do not try to talk your way out of it. Federal agents are trained interviewers, and even an accurate answer can be taken out of context or compared against other evidence. Tell them you want a federal gun charges attorney in Washington, then stop answering questions.
- Respect the warrant without surrendering extra ground. Never interfere with a lawful search, but do not sign consent forms or casually authorize agents to search beyond what the warrant permits.
- Preserve records that may tell your side of the story. That may include firearm receipts, transfer documents, text messages, emails, photos, location records, and communications with sellers or buyers.
- Do not contact witnesses or codefendants about the investigation. A message meant to “get everyone on the same page” can be interpreted as witness tampering or obstruction.
- Get legal representation before the government makes the next move. Early intervention may give your attorney time to investigate, preserve favorable evidence, communicate with prosecutors, and prepare for a search, arrest, or indictment.
Federal Weapons Charges You May Face in Washington
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
A conviction ordinarily requires more than showing that a gun was nearby. The government generally must prove knowing possession and that the accused knew they belonged to the category that prohibited possession.
Possession may be:
- Direct or actual possession: Agents or officers claim the weapon was in the person’s hand, pocket, waistband, bag, or immediate physical custody.
- Constructive possession: Prosecutors claim the person was not holding the gun but knew it was present and could control what happened to it.
A gun found under the same roof is not automatically possessed by everyone inside. When several people use the home, vehicle, room, or container where the weapon was recovered, the government’s control-and-knowledge theory may be open to challenge.
Using, Carrying, or Possessing a Gun Under 18 U.S.C. § 924(c)
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.
A § 924(c) sentence is generally stacked on top of the punishment for the underlying crime rather than served at the same time:
- Possession, use, or carrying: A minimum of five years
- Brandishing: A minimum of seven years
- Discharging the firearm: A minimum of 10 years
- Machine guns, silencers, or destructive devices: Potentially much higher mandatory minimums
A § 924(c) theory may rest entirely on where the gun was found. The government often argues that proximity to the following items shows the firearm was kept to further the alleged crime:
- Drugs or suspected drugs
- Cash allegedly connected to sales
- Scales, containers, or packaging materials
- Phones, notebooks, or transaction records
- Additional evidence of an alleged trafficking operation
A gun near drugs is not automatically a gun possessed “in furtherance” of trafficking. The defense may dispute knowledge, accessibility, ownership, proximity, and whether the firearm had any meaningful relationship to the alleged crime.
Buying a Firearm for Another Person
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.
Questions that may determine whether the transaction was lawful include:
- Whether another person supplied the purchase money
- Who directed the buyer toward a particular firearm
- Any agreement to transfer the gun after the sale
- The difference between a lawful gift and a purchase made as someone else’s agent
- What the buyer knew about the recipient’s background and intentions
Potential evidence may include text messages, payment records, store surveillance, purchase forms, and statements made to investigators.
Transporting or Transferring Firearms Unlawfully
A gun sale does not need to happen in a back alley to draw a federal trafficking charge. Section 933 applies to certain firearm transfers, receipts, and transportation when the accused knew or had reason to believe the weapons would end up in illegal hands.
A trafficking investigation may involve guns 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
Unlicensed Firearms Dealing
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.
The case may turn on the overall pattern of activity, including:
- 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
Federal Charges for False Firearm Purchase Statements
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.
Examples of information prosecutors may claim was falsified include:
- 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 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.
Possessing a Gun With a Removed Serial Number
When agents recover a firearm with a filed-down, scratched-off, or otherwise changed serial number, they may add another federal charge. Federal regulations prohibit certain conduct involving those firearms when the accused knew of the alteration.
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
The alleged alteration can affect more than guilt or innocence. It may also support an enhancement when the sentencing guidelines are calculated.
Privately Made Firearms and “Ghost Guns”
Building or assembling a gun for personal use does not, by itself, automatically make the firearm illegal. Federal problems involving a privately made firearm usually depend on the person involved, the weapon’s configuration, and what happened after it was made.
A privately made firearm case may turn on:
- The accused person’s legal ability to possess guns
- Whether the firearm was assembled lawfully
- Any later sale, transfer, or distribution
- Evidence of commercial manufacturing or dealing
- Missing, incomplete, or altered identifying marks
- An alleged connection to trafficking, drugs, or violent crime
Even where the firearm itself is not prohibited, the absence of a required serial number may increase the recommended guideline sentence.
National Firearms Act Violations
Certain firearms and devices are subject to stricter federal controls under the National Firearms Act. The law regulates their registration, manufacture, taxation, possession, and transfer.
NFA-regulated firearms include:
- Automatic weapons
- Rifles and shotguns below specified barrel-length requirements
- Silencers or sound suppressors
- Destructive devices
- Modified firearms that meet an NFA definition
- Other specially classified weapons
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 in Washington
Two people charged with firearm offenses may face very different outcomes. Federal sentencing depends on what prosecutors can prove, which statute applies, whether the law requires consecutive time, the accused’s criminal history, and how the court calculates the advisory guideline range.
| Charge or Allegation | Possible Federal Sentence |
|---|---|
| Unlawful firearm possession by a prohibited person under § 922(g) | Ordinarily punishable by as much as 15 years; the Armed Career Criminal Act may require at least 15 years for qualifying defendants |
| Firearm possession or use connected to a drug trafficking crime or crime of violence | Five years or more added to the underlying sentence, with seven years for brandishing and 10 years for firing the weapon |
| Buying a firearm for another person under § 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 |
| Federal gun trafficking under § 933 | Up to 15 years in federal prison |
| Operating as an unlicensed firearms dealer | Typically punishable by up to five years |
| Making false statements during a firearm purchase under § 922(a)(6) | Up to 10 years in federal prison |
| Receiving, transporting, or possessing a firearm with defaced identifying marks | Up to five years in many cases, with further sentencing exposure through an enhancement |
| Illegal possession, manufacture, or transfer of an NFA-regulated firearm | A possible 10-year prison term, financial penalties, and loss of the weapon |
| 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 |
The penalties listed above are starting points, not predictions. The sentence in a particular case may rise or fall based on the statute charged, the number and type of weapons, prior convictions, any mandatory minimum, and the calculation required by the federal sentencing guidelines.
Even after the prison term is calculated, the court may impose or trigger:
- Large financial penalties
- A term of federal supervised release following incarceration
- Seizure and forfeiture of guns, ammunition, cash, vehicles, and other alleged proceeds or instrumentalities
- Permanent or long-term restrictions on possessing firearms
- Barriers involving jobs, housing opportunities, and professional credentials
- Removal, inadmissibility, or other immigration problems for noncitizens
The number announced in court matters. Federal prisoners do not have access to conventional parole, and good-time reductions are limited, so the sentence served is usually close to the sentence ordered.
The 15-Year Armed Career Criminal Enhancement
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.
A § 922(g) defendant may face the enhancement when their record includes three prior offenses that satisfy ACCA’s federal definitions and were not all part of the same criminal occasion.
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.
A Washington federal firearms attorney may dispute:
- Whether the earlier conviction legally qualifies as a violent felony or serious drug offense
- Whether the permitted court records prove the necessary version of the offense
- Whether the prior crimes were truly committed on separate occasions
- Whether any conviction was overturned, set aside, expunged, or invalidated
- Whether firearm rights or other civil rights were restored
An ACCA case can hinge on a single prior offense. If one conviction does not qualify, the mandatory minimum may no longer apply, potentially removing years from the defendant’s exposure.
Federal Guideline Enhancements for Gun Charges
The sentence in a federal firearm case is influenced by more than the statute itself. Even when the law does not require a mandatory minimum prison term, guideline enhancements may substantially increase the advisory sentencing range.
Guideline enhancements may be tied to claims involving:
- The quantity of firearms involved
- Whether any firearm was stolen
- Defaced or missing identifying markings
- Transfers to prohibited persons or alleged trafficking schemes
- Possession of specially regulated NFA firearms or devices
- A connection between the firearm and separate felony conduct
- Reckless behavior during an attempted escape
- An alleged leadership or supervisory role
- Conduct the government claims obstructed the investigation or prosecution
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 Contact a Federal Firearms Defense 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.
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
The earlier a defense attorney becomes involved, the more options may exist. Depending on the circumstances, counsel can handle communications with investigators, help avoid unnecessary interviews, identify constitutional issues, preserve evidence, assess the strength of the government’s case, and present mitigating information before prosecutors decide whether to seek an indictment.
