Penal Code § 32900 PC - Bump Stock

1. What is Bump Stock?

Penal Code § 32900 PC is a California law that prohibits the possession, manufacture, import, sale, or transfer of bump stocks, also known as multiburst trigger activators. These devices are designed to increase the rate of fire of a semiautomatic firearm, making it function similarly to an automatic weapon.

This statute aims to enhance public safety by preventing the use of bump stocks, which have been linked to mass shootings and other violent incidents.

What is a Bump Stock?

A bump stock is a firearm accessory that modifies a semiautomatic weapon, allowing it to fire multiple rounds in rapid succession. It replaces the standard stock of a firearm and uses the firearm’s recoil to “bump” the trigger back into the shooter’s finger, enabling continuous rapid fire.

While bump stocks do not technically convert a semiautomatic firearm into an automatic weapon, they significantly increase the weapon’s firing speed, mimicking automatic fire.

Key Provisions of Penal Code § 32900 PC

The law prohibits the following activities involving bump stocks in California:

  1. Manufacturing

  2. Importing

  3. Selling or Offering for Sale

  4. Giving or Lending

  5. Possessing

Exceptions:
Certain individuals and organizations may legally possess bump stocks, including:

  • Historical societies and museums,

  • Authorized participants in film or television productions,

  • Law enforcement personnel for official duties.

These exemptions require compliance with applicable regulations and permissions.

Legal History of Bump Stocks

Bump stocks gained national attention following the tragic Las Vegas mass shooting on October 1, 2017, where the shooter used firearms equipped with bump stocks to fire approximately 90 rounds in 10 seconds, resulting in 58 deaths.

While federal law initially banned bump stocks in 2019 by classifying them as “machine guns,” this regulation was overturned by the U.S. Supreme Court on June 14, 2024. However, California’s ban on bump stocks has been in place since 1990 and remains unaffected by changes in federal law.

Differences Between Federal and California Laws

While the federal government no longer prohibits bump stocks as of June 2024, California continues to strictly regulate them under Penal Code § 32900 PC. This distinction highlights the state’s commitment to preventing the use of devices that can increase the lethality of firearms.

California Penal Code § 32900 PC plays a critical role in regulating firearm modifications that increase firing speed, such as bump stocks. Violating this law can result in serious consequences, including jail time, fines, and permanent confiscation of the device. However, legal defenses such as lack of knowledge, lawful possession, or constitutional violations can be used to fight these charges.

If you or someone you know is facing charges under Penal Code § 32900 PC, it’s essential to consult an experienced criminal defense attorney. At Grace Legal Group, we specialize in defending clients against firearms and weapon-related charges.

Penal Code § 32900 PC Law Reads As Followed:

Except as provided in Chapter 1 (commencing with Section 17700) of Division 2 of Title 2, any person in this state who manufactures or causes to be manufactured, imports into the state, keeps for sale, or offers or exposes for sale, or who gives, lends, or possesses any multiburst trigger activator is punishable by imprisonment in a county jail not exceeding one year or imprisonment pursuant to subdivision (h) of Section 1170.

2. What are Examples of Penal Code § 32900 PC?

California Penal Code § 32900 PC makes it illegal to possess, manufacture, sell, or import bump stocks, also known as multiburst trigger activators. These devices modify semiautomatic firearms to mimic the rapid-fire capabilities of automatic weapons. Understanding the law is easier with real-world examples that illustrate the kinds of actions that could lead to a violation.

Examples of Penal Code § 32900 PC Violations

1. Possessing a Bump Stock Without Authorization

Scenario:
A firearm owner purchases a bump stock online and installs it on their semiautomatic rifle. During a routine traffic stop, police find the modified weapon in the vehicle.

Violation:
Possessing a bump stock is prohibited under Penal Code § 32900 PC. Even if the owner did not intend to use it, possession alone constitutes a violation.

2. Selling Bump Stocks at a Gun Show

Scenario:
A vendor at a gun show in California offers bump stocks for sale, advertising them as “collector’s items.” Law enforcement conducting inspections at the event discovers the illegal devices.

Violation:
Selling or offering bump stocks for sale is a direct violation of Penal Code § 32900 PC, regardless of whether the sale is completed.

3. Importing Bump Stocks into California

Scenario:
An individual orders bump stocks from a seller in another state and has them shipped to their California residence. The package is intercepted by customs officials or law enforcement.

Violation:
Importing bump stocks into California is illegal under Penal Code § 32900 PC, regardless of the source or intended use.

4. Lending a Bump Stock to a Friend

Scenario:
A gun enthusiast lends a bump stock to a friend who wants to test it at a private shooting range. Law enforcement later discovers the device during an unrelated investigation.

Violation:
Lending a bump stock, even temporarily, violates Penal Code § 32900 PC. Both the owner and the borrower could face charges.

5. Displaying a Bump Stock in a Museum Without Proper Authorization

Scenario:
A small-town museum includes a bump stock in a firearms exhibit but fails to obtain the necessary permissions from state authorities.

Violation:
While museums may legally display bump stocks, failing to secure proper authorization would still violate Penal Code § 32900 PC.

6. Using a Bump Stock in a Public Shooting Incident

Scenario:
An individual uses a firearm equipped with a bump stock during a mass shooting, resulting in multiple injuries. Police recover the modified weapon at the scene.

Violation:
Using a bump stock in any capacity violates Penal Code § 32900 PC. This act could also lead to additional charges for the related criminal activity.

7. Claiming Unawareness of Ownership

Scenario:
An individual inherits a firearm collection from a relative, including a bump stock. The new owner keeps the bump stock without realizing it is illegal.

Violation:
Even unintentional possession of a bump stock violates Penal Code § 32900 PC. However, lack of knowledge may be used as a legal defense.

3. What are The Common Defenses Against Penal Code § 32900 PC?

California Penal Code § 32900 PC criminalizes the possession, manufacture, sale, or importation of bump stocks (multiburst trigger activators). If you are charged with violating this law, you may feel overwhelmed, but several legal defenses can be used to challenge the charges and potentially reduce or dismiss them. The best defense will depend on the specifics of your case, but here are some common strategies used in cases involving bump stocks.

1. Lack of Knowledge

To be convicted under Penal Code § 32900 PC, the prosecution must prove that you knowingly possessed, manufactured, imported, or sold a bump stock. If you were unaware that the item in your possession was a bump stock, you may have a strong defense.

Example:
You inherited a firearm collection from a relative and were unaware that a bump stock was included in the items.

Legal Argument:
You lacked the knowledge or intent required to violate Penal Code § 32900 PC.

2. The Bump Stock Belonged to Someone Else

If the bump stock in question was found in a shared space or someone else’s property, you may be able to argue that you were not in possession of the device.

Example:
A bump stock is discovered in your car, but the item belongs to a friend who borrowed your vehicle and left it there.

Legal Argument:
You did not have ownership or control over the bump stock.

3. You Were Transporting the Bump Stock for Lawful Disposal

California law allows individuals to transport prohibited items like bump stocks to law enforcement for lawful disposal. If you possessed the bump stock solely for this purpose, you could argue that your actions were lawful.

Example:
You found a bump stock in your attic and were driving to the police station to turn it in when law enforcement stopped you.

Legal Argument:
You were in possession of the bump stock for the purpose of lawful disposal and had no intent to use or sell it.

4. You Had Legal Authorization

Certain individuals and entities are exempt from the restrictions of Penal Code § 32900 PC. These include:

  • Law enforcement personnel acting in their official capacity,

  • Museums or historical societies with proper permissions,

  • Authorized participants in film or television productions.

Example:
You are a museum curator displaying the bump stock as part of a historical firearms exhibit with state approval.

Legal Argument:
Your possession of the bump stock was lawful under one of the exemptions provided in Penal Code § 32900 PC.

5. The Bump Stock Was Found During an Illegal Search

If the bump stock was discovered during an unlawful search, such as one conducted without a warrant or probable cause, the evidence may be inadmissible in court.

Example:
Law enforcement searched your home without a warrant and found a bump stock in your garage.

Legal Argument:
Your Fourth Amendment rights were violated, and the evidence obtained during the illegal search must be excluded.

6. Police Misconduct

If law enforcement engaged in misconduct, such as planting evidence, coercing a confession, or failing to follow proper procedures, you may have grounds to challenge the charges.

Example:
A law enforcement officer planted a bump stock in your vehicle during a traffic stop and falsely accused you of possession.

Legal Argument:
The charges are based on misconduct, and the case against you should be dismissed.

7. The Device Does Not Meet the Definition of a Bump Stock

Penal Code § 32900 PC specifically applies to multiburst trigger activators as defined under California Penal Code § 16930. If the device in question does not meet this legal definition, it may not fall under the statute.

Example:
The item found in your possession is a gun accessory, but it does not increase the rate of fire or allow for rapid bursts.

Legal Argument:
The item does not qualify as a bump stock under the law.

8. Lack of Intent to Violate the Law

Intent is a critical element in many criminal cases. If you can show that you did not intend to violate the law, the prosecution’s case may weaken.

Example:
You purchased a firearm accessory online, not realizing that it was classified as a bump stock and illegal in California.

Legal Argument:
You lacked the criminal intent required for a conviction.

  1. Criminal Record

    • A felony or misdemeanor conviction will appear on your permanent record, potentially affecting future employment, housing, and education opportunities.

  4. Professional Licenses

    • Certain professional licenses, such as those required for law enforcement or security roles, may be revoked or denied.
