How to Build an AR-15 Lower Receiver

The AR-15 lower receiver is the heart of the rifle. It houses the trigger assembly, bolt carrier group, and magazine. It is also the part of the rifle that is serialized, so it is important to make sure that you build it correctly.

In this guide, we will walk you through the process of building an AR-15 lower receiver. We will cover everything from choosing the right parts to assembling the receiver. By the end of this guide, you will have a solid understanding of how to build an AR-15 lower receiver.

Choosing the Right Parts

The first step in building an AR-15 lower receiver is choosing the right parts. There are a few things to keep in mind when making your selections.

• Material: The AR-15 lower receiver can be made from a variety of materials, including aluminum, steel, and polymer. Aluminum is the most common material, as it is lightweight and strong. Steel is a good option for durability, while polymer is a good option for cost-effectiveness.
• Finish: The finish of the AR-15 lower receiver is purely a matter of personal preference. You can choose from a variety of finishes, including anodized, parkerized, and nitrided.
• Features: Some AR-15 lower receivers come with additional features, such as a flared magwell, a bolt catch, and a trigger guard. These features are not necessary, but they can make the AR-15 lower receiver more comfortable to use.

Assembling the Lower Receiver

Once you have chosen the right parts, you can begin assembling the AR-15 lower receiver. The assembly process is relatively simple, but it is important to follow the instructions carefully.

1. Install the trigger guard. The trigger guard is a metal plate that protects the trigger from being accidentally engaged. To install the trigger guard, align the two holes in the trigger guard with the two pins on the lower receiver. Then, insert the pins and tighten the screws.
2. Install the magazine catch. The magazine catch is a small metal lever that holds the magazine in place. To install the magazine catch, align the two holes in the magazine catch with the two pins on the lower receiver. Then, insert the pins and tighten the screws.
3. Install the bolt catch. The bolt catch is a small metal lever that catches the bolt carrier group when the magazine is empty. To install the bolt catch, align the two holes in the bolt catch with the two pins on the lower receiver. Then, insert the pins and tighten the screws.
4. Install the buffer tube. The buffer tube is a metal tube that houses the buffer spring and buffer. To install the buffer tube, align the two holes in the buffer tube with the two pins on the lower receiver. Then, insert the pins and tighten the screws.
5. Install the stock. The stock is a wooden or polymer piece that attaches to the buffer tube. To install the stock, align the two holes in the stock with the two pins on the buffer tube. Then, insert the pins and tighten the screws.

Finishing the Lower Receiver

Once you have assembled the AR-15 lower receiver, you can finish it by adding a coat of paint or Cerakote. This will protect the lower receiver from corrosion and wear.

Building an AR-15 lower receiver is a relatively simple process, but it is important to follow the instructions carefully. By following this guide, you can build a solid and reliable AR-15 lower receiver that will last for years to come.

Tools and Materials

The following tools and materials are required to build an AR-15 lower receiver:

• AR-15 lower receiver parts kit
• AR-15 lower receiver jig
• AR-15 lower receiver vice block
• AR-15 lower receiver roll pin punch set
• AR-15 lower receiver hammer
• AR-15 lower receiver torque wrench
• AR-15 lower receiver grease
• AR-15 lower receiver oil
• AR-15 lower receiver cleaning kit

Step-by-Step Instructions

1. Assemble the AR-15 lower receiver parts kit. This includes installing the trigger guard, magazine catch, bolt catch, buffer tube, and stock.
2. Install the AR-15 lower receiver jig in a vise. The jig will hold the lower receiver in place while you work on it.

building an AR-15 lower receiver is a relatively simple process, but it is important to follow the instructions carefully and to use quality parts. By taking your time and being careful, you can build a lower receiver that will be reliable and accurate.

Here are some key takeaways from this article:

• AR-15 lower receivers are the foundation of the rifle, and they must be strong and durable.
• The lower receiver is responsible for the trigger, hammer, safety, and magazine release.
• There are two main types of AR-15 lower receivers: forged and billet.
• Forged lowers are typically less expensive, but billet lowers are stronger and more precise.
• The most important part of building an AR-15 lower receiver is to follow the instructions carefully.
• By taking your time and being careful, you can build a lower receiver that will be reliable and accurate.
