Build Your Own Ar-15 In California: A Complete Step-By-Step Guide

Building your own AR-15 in California can be both a rewarding and empowering experience. However, it requires careful planning, attention to detail, and a thorough understanding of California’s specific firearm laws. This guide aims to provide a comprehensive, step-by-step process to help you navigate the complexities of assembling your own AR-15 while adhering to state regulations. Let's get started! 🔨

Understanding California's Firearm Laws

Before you dive into the assembly process, it’s crucial to familiarize yourself with California's unique firearm laws. California has strict regulations that differ significantly from other states. Here are some key points to consider:

• Featureless AR-15 Requirements: In California, an AR-15 must adhere to "featureless" definitions if you want to avoid registering it as an assault weapon. This means you can’t have features like a pistol grip or a collapsible stock.
• Serialized Receiver: The lower receiver must be serialized, either as a factory-built unit or one that you've manufactured yourself.
• Background Check: You must undergo a background check and follow the California Department of Justice (DOJ) guidelines.

Understanding these regulations is fundamental before you begin your build.

Step 1: Gather Your Parts

To successfully build an AR-15, you’ll need to gather the following components:

Pro Tip: Ensure all parts are compliant with California regulations before purchasing.

Step 2: Assemble the Lower Receiver

Tools Needed:

• Armorer's wrench
• Punch set
• Hammer
• Screwdriver

Steps to Assemble:

1. Install the Trigger: Start by inserting the trigger into the lower receiver, securing it with the appropriate pins.
2. Add the Hammer: Next, place the hammer in position and insert its pin.
3. Install the Selector Switch: Insert the selector switch and secure it.
4. Attach the Buffer Tube: Screw the buffer tube onto the back of the lower receiver.
5. Install the Stock: Attach a fixed stock to comply with California's featureless law.

Step 3: Assemble the Upper Receiver

Steps to Assemble:

1. Attach the Barrel: Insert the barrel into the upper receiver, making sure it is properly seated.
2. Install the Gas Block and Tube: Position the gas block over the gas port on the barrel and slide in the gas tube.
3. Insert the Bolt Carrier Group: Place the BCG into the upper receiver and ensure it operates smoothly.
4. Add the Charging Handle: Insert the charging handle in the designated slot.

Step 4: Merge the Upper and Lower Receivers

To finalize your AR-15, simply align the upper and lower receivers and pin them together. Ensure that everything is functioning correctly before proceeding.

Common Mistakes to Avoid

While building your AR-15, it's easy to make mistakes. Here are some common pitfalls to watch out for:

• Ignoring Compliance: Make sure all components meet California regulations to avoid legal issues.
• Rushing the Build: Take your time; haste can lead to improper assembly or overlooked steps.
• Forgetting to Lubricate: Neglecting to lubricate components can lead to malfunctions.
• Not Checking Compatibility: Ensure parts are compatible with your lower receiver to avoid frustrations later.

Troubleshooting Issues

If you encounter problems during assembly or operation, consider these troubleshooting tips:

• Failure to Feed: Check if your magazine is properly seated and ensure your BCG is functioning.
• Failure to Eject: Inspect the gas system for blockages and verify that the gas tube is properly installed.
• Light Primer Strikes: Ensure your firing pin is not damaged and that the trigger group is correctly assembled.
