Essential Materials For Building An Ar-15: A Comprehensive Guide

Building an AR-15 can be a thrilling and rewarding experience for gun enthusiasts. With the right materials and a little bit of know-how, you can customize a rifle to suit your preferences and needs. Whether you're a seasoned builder or a newcomer to the world of firearms, understanding the essential materials involved in constructing an AR-15 is key to your success. Let’s dive into the components, tips, and common pitfalls to avoid as you embark on your build.

Understanding the AR-15 Components

An AR-15 is a modular rifle that consists of several core components, each playing a critical role in its functionality. Here’s a breakdown of the essential parts you’ll need:

1. Lower Receiver

The lower receiver is the foundation of the AR-15 and is the only part classified as a firearm. When building your AR-15, ensure that you purchase a lower receiver that is compatible with the rest of your components.

2. Upper Receiver

The upper receiver houses the barrel, bolt carrier group, and charging handle. You’ll want to choose between a stripped upper (just the shell) and a complete upper (which comes with assembled components).

3. Barrel

Selecting the right barrel is crucial as it significantly influences the rifle's accuracy and overall performance. Consider the length, twist rate, and caliber when making your choice.

4. Bolt Carrier Group (BCG)

The BCG is essential for chambering and firing rounds. This assembly includes the bolt, carrier, firing pin, and gas key. You’ll want to choose a BCG made from high-quality materials to ensure durability.

5. Stock and Buffer Tube

The stock provides stability and comfort while aiming and shooting. The buffer tube houses the recoil spring and buffer, which are necessary for cycling the action. Make sure to select a stock that fits your shooting style.

6. Handguard

A handguard allows for the attachment of accessories, such as lights and grips. You can choose between a free-floating or drop-in handguard based on your preference and intended use.

7. Lower Parts Kit (LPK)

The LPK contains all the small parts required to complete the lower receiver, including the trigger, hammer, and safety selector. It’s important to ensure all parts are compatible with your lower receiver.

8. Grip

The grip provides the necessary hold on your rifle. There are many ergonomic options available that enhance comfort and control during use.

9. Sights or Optics

Depending on your shooting style, you may opt for iron sights or a red dot/optical scope. Choose an option that fits your shooting distance and accuracy needs.

10. Magazine

Don’t forget about magazines! You'll need them to hold your ammunition. Select a capacity that complies with your local laws and suits your intended use.

Essential Tools for Building an AR-15

Aside from the materials, having the right tools will make your building process smoother. Here’s a list of must-have tools:

Tips for Building Your AR-15

1. Take Your Time

Building an AR-15 is a process that requires attention to detail. Rushing can lead to mistakes.

2. Read Instructions

Before you start assembling, read through any manuals or guides related to your specific parts. This will save you headaches later on.

3. Check Compatibility

Ensure that all components you choose are compatible with each other. A mismatch can cause serious operational issues.

4. Use Quality Materials

Investing in high-quality components ensures reliability and performance. Cut corners at your own risk.

5. Practice Safety

Always adhere to gun safety rules during assembly and handling. Treat every firearm as if it is loaded.

Common Mistakes to Avoid

1. Over-Torquing Fasteners: This can strip threads and damage components. Always refer to manufacturer torque specifications.

2. Ignoring Local Laws: Ensure that your build complies with state and federal regulations regarding firearm assembly and ownership.

3. Skipping the Function Check: After assembly, always conduct a function check to ensure everything is working correctly before taking your rifle to the range.

Troubleshooting Issues

If you encounter any issues during the build, here are a few common problems and solutions:

• Failure to Feed: This could indicate an issue with the magazine or the BCG. Check for obstructions and ensure compatibility.

• Double Feed: This often occurs due to improper magazine seating. Make sure your magazine is properly inserted.

• Misfires: Could stem from a bad primer or a faulty firing pin. Inspect the cartridge and firing pin to troubleshoot.
