Build an AR-15 Kit: A Comprehensive Guide
Building your own AR-15 kit can be a rewarding and exciting project. Whether you’re a seasoned gun enthusiast or a beginner, assembling your own rifle can provide a sense of accomplishment and allow you to customize your firearm to your specific needs. In this guide, we’ll walk you through the process of building an AR-15 kit, covering everything from selecting the right components to assembling and testing your finished rifle.
Choosing the Right Components
Before you start building your AR-15 kit, it’s important to choose the right components. Here’s a breakdown of the key components you’ll need:
| Component | Description |
|---|---|
| Receiver | The receiver is the frame of the rifle and houses the trigger group, bolt carrier group, and magazine. It comes in two types: mil-spec and commercial. |
| Bolt Carrier Group (BCG) | The BCG is responsible for cycling the action of the rifle. It includes the bolt, firing pin, and gas key. |
| Barrel | The barrel is the tube that the bullet travels through. It comes in various lengths and calibers, so choose one that suits your needs. |
| Handguard | The handguard is the tube that covers the barrel and provides a place to hold the rifle. It comes in various materials and designs. |
| Stock | The stock is the part of the rifle that you hold against your shoulder. It comes in various lengths and designs, so choose one that fits your body type and preferences. |
| Trigger Group | The trigger group includes the trigger, hammer, and sear. It’s responsible for the firing of the rifle. |
| Magazine | The magazine holds the ammunition. Choose a magazine that fits your rifle and holds the desired number of rounds. |
When selecting components, consider the following factors:
- Caliber: The caliber of your rifle will determine the type of ammunition you can use. Common calibers for AR-15s include .223 Remington, 5.56 NATO, and .308 Winchester.
- Length: The overall length of the rifle will affect its maneuverability and ease of carry. Consider the length of pull of the stock and the barrel length when making your choice.
- Material: The materials used in the components will affect the weight, durability, and aesthetics of the rifle. Common materials include aluminum, steel, and polymer.
Assembling Your AR-15 Kit
Once you’ve selected your components, it’s time to assemble your AR-15 kit. Here’s a step-by-step guide to help you through the process:
- Install the barrel into the receiver. Make sure it’s properly aligned and secured.
- Attach the handguard to the barrel. Most handguards use a hex bolt and nut for attachment.
- Install the bolt carrier group into the receiver. Make sure the gas key is properly seated and secured.
- Install the trigger group into the receiver. This may require removing the bolt carrier group.
- Attach the stock to the receiver. Most stocks use a takedown bolt for attachment.
- Install the magazine into the magazine well. Make sure it’s properly seated and secured.
- Perform a function check to ensure that the rifle is operating correctly.
Testing Your Rifle
After assembling your AR-15 kit, it’s important to test it to ensure that it’s functioning properly. Here’s a simple test you can perform:
- Load a magazine with ammunition.
- Insert the magazine into the rifle.
- Secure the bolt carrier group in the open position.
- Attempt to fire the rifle. If it fires, the rifle is functioning correctly.
