Federal gun charges in Maryland 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 gun does not have to be used in the way most people imagine. Federal charges may grow out of constructive possession, a straw purchase, false statements to a dealer, access to an unregistered weapon, or a firearm found near alleged criminal activity. In some cases, the firearm allegation is what turns a difficult prosecution into one carrying years of additional prison exposure.

When federal agents and prosecutors set their sights on someone in Maryland, Combs Waterkotte is prepared to push back. Our federal criminal defense team serving Maryland 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?
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.
Common reasons a firearm case enters federal court include:
- 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 Maryland? 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.
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 Maryland, 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.
Common Federal Gun Charges in Maryland
Possession of a Firearm by a Prohibited Person
The phrase “felon in possession” covers only part of 18 U.S.C. § 922(g). The statute reaches multiple classes of people barred from possessing guns or ammunition, even when the firearm was never fired or displayed.
A person may be legally barred from possessing a gun or ammunition because of:
- 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.
The government may try to prove possession in either of two ways:
- 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)
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 statute carries mandatory minimum prison terms that generally run back-to-back with the sentence imposed for the related 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
No shot needs to be fired for prosecutors to bring this charge. They may claim the firearm helped secure, protect, or advance the alleged operation because it was located close to:
- 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.
Straw Purchasing a Firearm
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.
The government and defense may focus 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
These cases leave a digital and documentary trail. Prosecutors may rely on Form 4473, receipts, cash transfers, text conversations, security footage, firearm tracing records, and interview statements to argue who the real buyer was.
Federal Firearms Trafficking Charges
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.
Federal agents may characterize firearms as trafficked when they were allegedly:
- 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
When Private Gun Sales Become Federal Charges
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:
- How many firearms were sold and how often sales occurred
- Whether guns were purchased and quickly resold
- Online listings, advertisements, or social media offers
- Messages with prospective buyers and records of payment
- Whether the person expected to earn money from the transactions
- Whether firearms were kept on hand for future customers
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 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
Possible defenses may focus on confusion, an ambiguous question, an honest mistake, or information that was not material to the transaction. The wording of the form and the accused person’s knowledge at the time can matter greatly.
Federal Charges Involving an Altered Firearm 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 alteration was visible or known to the accused
- Whether the serial number was legally “removed, obliterated, or altered”
- What laboratory testing reveals about the original markings
- Whether prosecutors can prove knowing possession of that specific gun
An altered serial number may also increase the recommended sentence under the federal sentencing guidelines.
“Ghost Gun” Investigations
A privately made firearm is not automatically illegal simply because an individual assembled it. Criminal exposure may arise depending on:
Investigators may focus 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
Even where the firearm itself is not prohibited, the absence of a required serial number may increase the recommended guideline sentence.
Federal National Firearms Act Charges
A firearm that is lawful in one configuration can fall under much stricter rules after certain modifications. The National Firearms Act governs several categories of weapons and devices through registration, taxation, transfer, and manufacturing requirements.
NFA rules may apply to:
- Machine guns
- Short-barreled rifles
- Short-barreled shotguns
- Silencers and suppressors
- Destructive devices
- Certain weapons classified as “any other weapon”
Federal agents may bring NFA charges when they believe a regulated item was never registered, was made or transferred without approval, or had required markings removed. The potential consequences include substantial fines, forfeiture, and up to a decade in federal custody.
Federal Firearm Sentences in Maryland
There is no universal sentence for a federal gun conviction. Prison exposure can change based on the charge, the firearm involved, prior convictions, any connection to another alleged crime, and the calculation required by the federal sentencing guidelines.
| Federal Gun Offense | Maximum or Mandatory Penalty |
|---|---|
| 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 | A consecutive mandatory term beginning at five years and increasing based on how the firearm was allegedly used |
| Straw purchasing under 18 U.S.C. § 932 | Potentially 15 years in federal prison, or 25 years when the alleged circumstances involve certain intended serious crimes |
| Unlawful transportation or transfer of firearms | Up to 15 years in federal prison |
| Dealing firearms without a required federal license | Generally a five-year maximum term of imprisonment |
| Lying about material information during a federally regulated gun sale | Potential imprisonment for up to 10 years |
| Knowing possession of a gun with a removed or changed serial number | Generally up to five years in federal prison, with possible sentencing enhancements |
| Federal charges involving silencers, short-barreled firearms, machine guns, or other NFA items | As much as 10 years of imprisonment along with fines and forfeiture |
| Unlawful possession, receipt, or transfer of a machine gun | 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.
Prison is only one possible consequence of a federal firearm conviction. A sentence may also involve:
- Substantial fines
- Supervised release after imprisonment
- Forfeiture of firearms, ammunition, money, vehicles, or other property
- Loss of firearm rights
- Restrictions on employment, housing, and professional licensing
- Immigration consequences for noncitizens
There is no traditional parole in the federal system. Limited good-time credit may reduce an eligible person’s release date, but most of the sentence pronounced by the judge will still have to be served.
How the Armed Career Criminal Act Can Increase a Gun Sentence
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.
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.
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.
An experienced Maryland federal gun charges 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
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 Maryland Firearm Cases
A firearm case can carry substantial sentencing exposure even without a mandatory minimum. The United States Sentencing Guidelines may recommend a much higher prison range based on specific offense characteristics.
The advisory guideline range may increase if the government proves factors such as:
- 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 to Call a Federal Gun Defense Attorney
You should contact a federal defense lawyer in Maryland 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
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.
