Build Your Own AR-15: A Comprehensive Guide
Building your own AR-15 rifle can be a rewarding and exciting project. Whether you’re a seasoned gun enthusiast or a beginner, this guide will walk you through the process step by step. From selecting the right components to assembling and testing your rifle, we’ve got you covered.
Choosing the Right Parts
Before you start building your AR-15, you need to choose the right parts. Here’s a breakdown of the essential 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. |
| Bolt Carrier Group (BCG) | The BCG is responsible for cycling the rounds and is one of the most critical components of the rifle. |
| Barrel | The barrel determines the rifle’s caliber and length, which affects its performance and accuracy. |
| Handguard | The handguard protects the barrel and provides a place to grip the rifle. |
| Stock | The stock is the part of the rifle that you hold against your shoulder and is available in various lengths and materials. |
| Trigger Group | The trigger group includes the trigger, hammer, and sear and is responsible for the firing mechanism. |
| Magazine | The magazine holds the rounds and is available in various capacities and materials. |
When selecting these components, consider the following factors:
- Caliber: The most common calibers for AR-15s are .223 Remington and 5.56 NATO.
- Barrel Length: A longer barrel will typically provide better accuracy and velocity, but it may also be heavier and more difficult to maneuver.
- Handguard: Look for a handguard that is comfortable to hold and provides adequate protection for the barrel.
- Stock: Choose a stock that fits your body type and preferences, and consider the length of pull and cheek weld.
Assembling Your AR-15
Once you’ve selected your components, it’s time to assemble your AR-15. Here’s a step-by-step guide to help you through the process:
- Install the barrel into the receiver. Ensure that the barrel nut is tight and secure.
- 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 BCG is properly seated and the charging handle is attached.
- Install the trigger group into the receiver. This may require removing the front sight base and gas block.
- Attach the stock to the receiver. Most stocks use a takedown lever and pin for attachment.
- Install the magazine into the magazine well. Ensure that the magazine is properly seated and secure.
- Install the front sight and rear sight. Most AR-15s use a Picatinny rail for mounting sights.
- Perform a function check to ensure that the rifle is operating correctly.
Testing Your Rifle
After assembling your AR-15, it’s essential to test it to ensure that it’s functioning correctly. Here’s what you need to do:
- Load a magazine with ammunition and insert it into the rifle.
- Check the rifle for any signs of damage or wear.
- Perform a dry fire test to ensure that the rifle is cycling correctly.
- Load the rifle with live ammunition and fire a few rounds to test its accuracy and reliability.
Maintenance and Upkeep
Proper maintenance and upkeep are crucial for ensuring the longevity and performance of your AR-15. Here are some tips to help you keep your rifle in top condition
