• Cost Savings: Often, building your own AR-15 can save you money compared to purchasing a factory-made one, especially if you’re careful about parts selection.
• Learning Experience: The process of assembling your rifle provides insight into its mechanics, enhancing your understanding and appreciation of the firearm.

Essential Tools and Equipment

Before diving into the assembly, it's essential to gather the right tools. Having the right equipment will not only make the process smoother but also safer. Here’s a basic list:

Step-by-Step Guide to Building Your AR-15

Let’s dive into the actual assembly process! Below is a simplified step-by-step guide to building your AR-15.

1. Gather Your Parts

Your AR-15 will consist of two main parts: the lower receiver and the upper receiver. Here’s a basic parts list for each:

Lower Receiver Components:

• Lower Receiver
• Trigger Assembly
• Hammer
• Selector Switch
• Pistol Grip
• Buffer Tube Assembly
• Stock

Upper Receiver Components:

• Upper Receiver
• Barrel
• Gas System (gas block and tube)
• Handguard
• BCG (Bolt Carrier Group)
• Charging Handle

2. Start with the Lower Receiver

The first step is to assemble the lower receiver. Here’s a simple breakdown:

• Install the Trigger and Hammer:

  • Insert the trigger assembly into the lower receiver.
  • Use the appropriate pins to secure it in place.

• Attach the Pistol Grip:

  • Align the grip with the receiver and screw it in tightly.

• Install the Buffer Tube:

  • Screw the buffer tube into the lower receiver while ensuring that the buffer retaining pin is properly positioned.

3. Assemble the Upper Receiver

Now, let’s move on to the upper receiver:

• Attach the Barrel:

  • Fit the barrel into the upper receiver and secure it with the barrel nut using the armorer’s wrench. Be sure to apply the manufacturer-recommended torque specifications.

• Install the Gas Block and Tube:

  • Position the gas block at the specified distance from the receiver and insert the gas tube through the block and into the upper receiver.

• Add the BCG and Charging Handle:

  • Slide the charging handle into the upper receiver, followed by the bolt carrier group.

4. Join the Upper and Lower Receivers

Once both components are assembled, it’s time to connect them:

• Align the takedown pins from the lower receiver with the upper receiver and press them into place.

5. Final Touches

• Attach the Handguard:

  • Depending on the type of handguard you have chosen (free float or drop-in), install it accordingly.

• Inspect and Lubricate:

  • Go through your assembly to ensure everything is tight and functioning. Lubricate moving parts as necessary.

6. Test Your Build

• Function Check:
  • Conduct a function test to ensure everything operates smoothly without ammunition.

Common Mistakes to Avoid

When building your own AR-15, several pitfalls can detract from your success. Here are a few common mistakes to be wary of:

• Over-tightening Screws: Over-tightening can strip threads or damage components. Always adhere to manufacturer torque specifications.

• Ignoring Compatibility: Make sure that all your parts are compatible with each other. Double-check the specifications before purchasing components.

• Neglecting Safety Precautions: Never skip safety practices. Wear eye protection and ensure you're working in a clean and safe environment.

Troubleshooting Common Issues

Even the best builders encounter hiccups along the way. Here are some troubleshooting tips for frequent problems:

• Failure to Feed: If your rifle isn't feeding properly, check for issues with the magazine, ammunition, or the BCG.

• Failure to Eject: A failure to eject can occur due to improper lubrication or a dirty chamber. Clean and lubricate as necessary.

• Misalignment: If parts seem misaligned, double-check the installation instructions and make sure that everything is properly seated.
