How to Build a Reliable AR-15 From Scratch

Building your own AR-15 rifle from scratch can be a rewarding experience for gun enthusiasts and hobbyists alike. By customizing each component to your preferences, you can create a reliable and high-performance firearm that suits your needs. In this guide, we will walk you through the process of building a reliable AR-15 from scratch, covering everything from selecting the right parts to assembling the rifle.

1. Understanding the Basics of an AR-15

Before you start building your AR-15, it’s essential to have a good understanding of the basic components that make up the rifle. The AR-15 is a versatile and modular platform that allows for easy customization. Here are some of the key components you’ll need to consider:

• Upper Receiver: This is the top half of the rifle that houses the barrel, bolt carrier group, and handguard.
• Lower Receiver: This is the bottom half of the rifle that contains the trigger group and magazine well.
• Barrel: The barrel is where the bullet travels through, and its length and caliber will affect the rifle’s performance.
• Handguard: The handguard protects your hands from the hot barrel and allows you to attach accessories like lights or grips.
• Stock: The stock provides stability and comfort while shooting, and there are various options available, such as fixed or adjustable stocks.

2. Selecting High-Quality Parts

When building an AR-15, it’s crucial to choose high-quality parts to ensure reliability and performance. Here are some tips for selecting the right components:

• Research reputable manufacturers: Look for well-known brands with a track record of producing reliable AR-15 parts.
• Consider your budget: Decide how much you’re willing to spend on each component and prioritize quality over price.
• Read reviews: Check online reviews and forums to see what other builders have to say about specific parts.

3. Assembling Your AR-15

Once you’ve gathered all the necessary components, it’s time to start assembling your AR-15. Here’s a step-by-step guide to help you put together your rifle:

• Start by attaching the barrel to the upper receiver using a barrel nut wrench.
• Install the bolt carrier group into the upper receiver and ensure that it moves smoothly.
• Attach the handguard to the upper receiver, making sure it’s securely in place.
• Insert the lower parts kit into the lower receiver, including the trigger group and magazine release.
• Attach the upper receiver to the lower receiver using push pins or screws.

4. Testing and Troubleshooting

After assembling your AR-15, it’s essential to test fire it at a range to ensure everything is functioning correctly. Here are some troubleshooting tips if you encounter any issues:

• If your rifle fails to cycle properly, check for any obstructions in the barrel or gas system.
• If you experience feeding issues, inspect the magazine for any defects or try using different ammunition brands.
• If your rifle has accuracy problems, consider upgrading your optics or adjusting your sights for better alignment.

5. Maintaining Your AR-15

To keep your AR-15 running smoothly and reliably, regular maintenance is crucial. Here are some maintenance tips to help prolong the lifespan of your rifle:

• Clean your rifle after each use using a cleaning kit with brushes, solvent, and lubricant.
• Inspect all components for wear or damage regularly and replace any parts that show signs of wear.
