Possession of an unregistered or ghost gun in California has become a major focus for state law because these weapons are hard to trace and easy to make. California law treats ghost guns, unregistered assault weapons, and other untraceable firearms as serious crimes that can lead to harsh penalties. A conviction can result in county jail, state prison, or long-term restrictions on firearm ownership. These cases move fast because law enforcement agencies see them as a threat to public safety. At Hurwitz Law Group, our criminal defense lawyers defend people facing ghost gun charges and help them understand their legal options.
Ghost guns are homemade firearms built from parts, kits, or other components that lack serial numbers. Under California's ghost gun laws, many of these weapons must have serial numbers and meet legal requirements before someone can possess them. An unregistered firearm is one that state law requires to be registered, such as assault weapons that fall under strict laws and older registration deadlines. When someone fails to meet these rules, the state may file misdemeanor or felony charges that put their future at risk. We help clients understand how California law applies to each type of firearm and explain the legal consequences tied to each case.
An unserialized ghost gun is often made from firearm precursor parts, kits, or even 3D-printed pieces. These homemade firearms lack serial numbers from a licensed maker and cannot be traced by law enforcement officers. California's ghost gun laws, including Assembly Bills 1621 and 2156, now require many of these weapons to be serialized by the California Department of Justice. The rules apply even when the firearm was built by the person who owns it. We guide clients through how the state views these weapons and why the law considers them untraceable.
An unregistered assault weapon is defined under Penal Code 30515, which sets strict limits on firearm possession. These firearms must meet specific registration requirements, and past registration deadlines have already closed. When someone still holds one, the state may claim illegal possession of an assault weapon. This can lead to felony charges and a permanent ban on firearm ownership. We help clients understand whether their firearm meets the legal definition and how state law applies to their case.

California has some of the strictest gun laws in the country, and many statutes overlap when dealing with ghost guns, which are illegal under state law. These rules cover unserialized firearms, unregistered assault weapons, and untraceable weapons that fall outside normal background checks. A person can face criminal charges even when they did not know the firearm belonged to a restricted category. Police enforcement moves fast because the state views these cases as threats tied to violent crimes. We guide clients through these laws and explain how each penal code section may affect the ghost gun case.
PC 30605 makes it a felony to possess an unregistered assault weapon. A conviction can result in state prison time, fines, and a long firearms prohibition. Some cases may lead to felony convictions that affect a criminal record for life. These rules apply even when the person never used the weapon or kept it as a collectible. We help clients respond to these felony charges with a strong defense strategy and clear legal representation.
Possible penalties include:
PC 23900 treats possession of an unserialized firearm as a wobbler offense. This means it may bring misdemeanor or felony charges, depending on the facts and prior criminal record. Penalties can include county jail, fines, or state prison for up to three years when the case involves other violations. These same regulations now cover firearm precursor parts and other kits used to build ghost guns. We work with clients to reduce the charge and protect them from harsh penalties.
Key factors include:
Other laws can increase the punishment for ghost gun violations. PC 29800 bans possession of firearms by a prohibited person, and this can add separate criminal charges when the person is barred from possessing firearms under state or federal law. Some cases also bring longer terms when the weapon is a loaded firearm or is tied to violent crimes. These enhancements can push jail time or state prison terms much higher. We look at each factor to limit exposure and protect the client’s future.
Enhancements may involve:
Charges linked to a ghost gun in California can arise from deliberate acts or simple mistakes. Some people fail to understand how strict California law has become following updates to the Penal Code and Assembly Bill rules. Others believe older firearms or homemade firearms fall outside state law. Police reports often show confusion about what items are legal or illegal firearm parts. We help clients sort through these issues when facing criminal charges.
Older federal law once allowed people to build guns at home without serial numbers. Today, California bans the possession of these weapons unless they are serialized through the California Department of Justice. Unserialized firearms now fall under the same regulations as all other firearms. Even firearm precursor parts can lead to charges when they allow someone to assemble untraceable weapons. We explain how state law changed and why the state treats these items as illegal possession.
Important points include:
Many people believe that an inherited gun or older weapon is exempt from ghost gun laws. But unregistered or unserialized firearms do not gain legal status just because they are old. For example, a gun found in the home or passed down from the family must still meet state law. Mistaken identity of the weapon or confusion about deadlines does not excuse the violation. We explain these rules and help clients avoid charges based on false accusations or misunderstandings.
Common scenarios include:

A strong defense strategy is vital because ghost gun violations carry a serious risk. An attorney from Hurwitz Law Group will challenge police reports, witness testimony, forensic evidence, and every claim the state makes. Many cases involve mistakes by law enforcement or unlawful search practices that violate rights under the Fourth Amendment. We work to suppress evidence when police enforcement lacked probable cause or performed an illegal search. Our law firm focuses on building a defense that protects the client from jail time and long-term harm.
One defense is to show that the person did not know the firearm was unserialized or required registration. Some people believe the firearm belonged to someone else or thought it was already legal. Others did not understand the strict laws on possessing firearms or transferring ghost guns. The state must prove the weapon was knowingly possessed. We use every fact to show why the client acted without intent.
Key points include:
Police often seize ghost guns during stops, searches, or investigations tied to other matters. If officers lacked probable cause or conducted an unlawful search, the evidence can be challenged. A motion to suppress can remove key items from the case. Many charges collapse when the weapon comes from an illegal search. We look for every opportunity to protect rights and reduce the impact of police enforcement errors.
Possible issues include:
Some items do not meet the legal definitions of a firearm, an assault weapon, or a ghost gun. Parts that cannot fire or pieces missing key elements may not qualify under the California penal code. Some cases involve forensic evidence that fails to prove the item is an illegal firearm. Others involve false accusations or mistaken identity of parts. We challenge every detail to show why the state’s claim does not fit the law.
Challenges may involve:
Is it now illegal to build your own gun in California?
You can still build one, but it must have a state-issued serial number from a licensed vendor before the work is complete. If not, the weapon may be treated as a ghost gun, illegal under strict state law. Many people do not know this rule, which leads to criminal defense issues later. We help clients understand the process so they do not face criminal charges for homemade weapons. Our law offices guide people through the steps to avoid violations.
I own an AR-15-style rifle. Is it an unregistered assault weapon?
It depends on the features and when it was acquired. Many rifles now fall under the assault weapon rules, and past registration windows have closed. If the weapon was not registered, it may be illegal under current law. We review each rifle to see how the penal code applies. This helps protect clients from mistakes that could harm their criminal record.
Can I get a serial number for my ghost gun now?
Yes, the state allows this through a licensed vendor who follows the legal requirements. But holding the weapon before this process is complete is a crime. Police enforcement treats these items as unserialized firearms even if you plan to serialize them later. We explain the process and help reduce the chance of charges. Our criminal defense team helps clients act before trouble begins.
What if the gun was a gift or I found it?
Possession is the key issue under state law. You must ensure the weapon is serialized and registered when required. Saying the firearm belonged to someone else is not a defense. We guide clients through the rules so they do not face charges for simple mistakes. Clear advice can prevent long-term problems.
Are ghost gun charges felonies?
PC 23900 is a wobbler, which means the charge may be a misdemeanor or a felony. The choice depends on the facts and the client’s record. Some cases result in felony convictions and severe penalties. We work to keep the case at the lowest level possible. This protects the client from jail time and limits their rights.
What is the first step I should take if charged?
Do not talk to law enforcement without a lawyer present. Contact a criminal defense attorney who knows California firearm rules right away. These cases move fast, and early mistakes can hurt your defense. We help clients stay safe and avoid statements that harm their case. A quick call can make a major difference in the outcome.
