Why Build an AR-15?
There are numerous reasons to consider building an AR-15:
- Customization: You have complete control over parts, allowing for a rifle tailored to your preferences.
- Learning Experience: Building your own AR-15 helps you understand the mechanics of the firearm.
- Cost-Effectiveness: Depending on your choices, you may save money compared to purchasing a pre-built rifle.
Essential Tools and Materials
Before starting your build, gather the necessary tools and parts. Here’s a table of the essential tools you'll need:
<table> <tr> <th>Tool</th> <th>Description</th> </tr> <tr> <td>Armorer’s Wrench</td> <td>Used to tighten the barrel nut and castle nut.</td> </tr> <tr> <td>Torque Wrench</td> <td>Ensures components are tightened to manufacturer specifications.</td> </tr> <tr> <td>Punch Set</td> <td>Essential for pushing out roll pins.</td> </tr> <tr> <td>Gunsmithing Hammer</td> <td>For driving pins without damaging components.</td> </tr> <tr> <td>Claw Tool or Vice</td> <td>Holds the lower receiver securely while building.</td> </tr> </table>
Parts List
You’ll need the following parts to build your AR-15:
- Lower Receiver: The core component that houses the trigger group.
- Upper Receiver: Contains the barrel and bolt carrier group.
- Barrel: Choose a length and caliber that suits your needs.
- Bolt Carrier Group (BCG): Essential for the operation of the AR-15.
- Handguard: Protects the barrel and provides a mounting area for accessories.
- Stock and Buffer Tube: Determines the rifle’s length and stability.
- Lower Parts Kit (LPK): Contains the necessary springs, pins, and trigger components.
Step-by-Step Building Process
Building your AR-15 is an exciting venture. Here’s a straightforward breakdown of the process:
Step 1: Assemble the Lower Receiver
- Insert the Trigger: Start by installing the trigger and hammer. Use your punch set to secure the pins.
- Install the Safety Selector: Make sure it’s functional and positions correctly.
- Add the Pistol Grip: Tighten it using the screw provided in your LPK.
- Attach the Stock: Fit the buffer tube and stock into the lower receiver.
Step 2: Build the Upper Receiver
- Install the Barrel: Tighten the barrel nut using your armorer's wrench.
- Attach the Gas Block and Tube: Secure the gas block, then slide in the gas tube.
- Insert the BCG: Ensure the charging handle is in place, then slide the BCG into the upper receiver.
Step 3: Marry the Upper and Lower Receivers
- Align and Secure: Fit the upper receiver onto the lower receiver, aligning the pins. Push the takedown pins in securely.
- Final Check: Ensure everything operates smoothly and check for proper function.
Common Mistakes to Avoid
Building an AR-15 can be a complex process, and mistakes can happen. Here are common pitfalls to watch out for:
- Over-tightening: This can damage components, particularly the upper receiver.
- Misalignment: Ensure parts align correctly to avoid malfunctions.
- Skipping the Manual: Always refer to the manufacturer’s manual for specific instructions related to your components.
Troubleshooting Issues
If you encounter issues during your build, here are some common problems and solutions:
- Failure to Feed: Check if the magazine is seated correctly and inspect the BCG for proper alignment.
- Stuck Components: If parts seem stuck, ensure you're using the right tools and applying sufficient force.
- Misfiring: This may be due to a faulty firing pin or malfunction in the trigger group; double-check your assembly.
