Yes, it is legal to build a gun in California, but there are important regulations and requirements that must be followed.
Building your own firearm, commonly known as DIY or homemade guns, is legal in California as long as certain conditions are met. However, it's crucial to understand and comply with the state's laws to ensure you stay within the bounds of legality.
First and foremost, it's important to note that building a gun for personal use is different from manufacturing firearms for sale or distribution. California law allows individuals to build their own firearms for personal use without the need for a license or registration. This is known as the "homemade firearm exemption."
However, there are several key requirements that must be met when building a gun in California:
Key Requirements for Building a Gun in California
| Requirement | Description | Penalty for Non-compliance | Relevant Law |
|---|---|---|---|
| Age Limit | Must be 21 years or older | Misdemeanor, up to 1 year in county jail, and/or a fine of up to $1,000 | Penal Code 27510 PC |
| Background Check | Must pass a background check | Felony, up to 3 years in state prison, and/or a fine of up to $10,000 | Penal Code 27545 PC |
| Firearm Safety Certificate | Must possess a valid Firearm Safety Certificate | Misdemeanor, up to 6 months in county jail, and/or a fine of up to $1,000 | Penal Code 31615 PC |
| 10-Day Waiting Period | Must observe a 10-day waiting period before receiving the firearm | Misdemeanor, up to 6 months in county jail, and/or a fine of up to $1,000 | Penal Code 26815(a) PC |
| Assault Weapons Ban | Cannot build assault weapons or .50 BMG rifles | Felony, up to 3 years in state prison, and/or a fine of up to $10,000 | Penal Code 30600 PC |
1. Eligibility: You must be eligible to possess firearms under state and federal law. This means you must be at least 18 years old to build a long gun (rifle or shotgun) and at least 21 years old to build a handgun.
2. Serial Number: The firearm you build must have a unique serial number engraved or permanently affixed to the frame or receiver. This serial number must be obtained from the California Department of Justice (DOJ) by completing a "Firearm Ownership Record" form and paying a fee.
3. Undetectable Firearms: It is illegal to build or possess firearms that are undetectable by metal detectors. This includes firearms made entirely of plastic or other materials that cannot be detected by standard security screening devices.
4. Prohibited Features: When building a firearm, you must ensure that it does not violate California's laws regarding prohibited features. For example, handguns must have a barrel length of at least 3.5 inches and must not have features such as a threaded barrel, a second handgrip, or a magazine capacity exceeding 10 rounds.
5. Transfer Restrictions: If you decide to sell or transfer a homemade firearm, you must comply with California's laws regarding private firearm transfers. This includes conducting the transfer through a licensed firearms dealer and completing the necessary background checks and paperwork.
It's important to stay informed about any changes or updates to California's gun laws, as regulations can evolve over time. Consulting with legal professionals or contacting the California DOJ directly can provide you with the most up-to-date information.
Remember, responsible gun ownership includes understanding and complying with the laws that govern firearms in your state. By following the regulations outlined by California law, you can exercise your right to build a gun while staying within the bounds of legality. Stay informed, stay safe, and exercise your rights responsibly.
