AR Builder: A Comprehensive Guide to Building Your Own AR-15
Building your own AR-15 can be an exciting and rewarding experience, whether you’re a firearm enthusiast, a hobbyist, or someone looking for a customized rifle. Using an AR builder allows you to tailor every aspect of your firearm to suit your needs, from performance and aesthetics to functionality. In this guide, we’ll explore the benefits of building an AR-15, the essential components, and a step-by-step process to complete your build successfully.
Why Build Your Own AR-15?
Many gun owners prefer to build their AR-15 rather than purchasing a pre-assembled model. Here are some key reasons why:
1. Full Customization
With an AR builder, you have complete control over every component, allowing you to optimize your rifle for hunting, self-defense, or competition shooting.
2. Cost Efficiency
While a high-end factory AR-15 can be expensive, building your own can save you money, especially if you source components smartly.
3. Understanding Firearm Mechanics
Assembling an AR-15 provides hands-on knowledge about firearm function and maintenance, making you a more informed gun owner.
4. Compliance with Local Laws
Building your own rifle ensures you adhere to state-specific regulations by choosing compliant parts and configurations.
Essential Components of an AR-15
Before diving into the building process, it’s essential to understand the primary components of an AR-15:
- Lower Receiver – The serialized part legally considered the firearm.
- Upper Receiver – Houses the bolt carrier group and barrel.
- Barrel – Affects accuracy, velocity, and overall rifle performance.
- Bolt Carrier Group (BCG) – Enables chambering, firing, and cycling of rounds.
- Handguard – Offers protection and accessory mounting points.
- Stock and Buffer System – Influences recoil control and shooting comfort.
- Trigger Assembly – Determines shooting sensitivity and accuracy.
- Gas System – Facilitates the cycling of rounds by directing gas pressure.
Step-by-Step Guide to Building an AR-15
Step 1: Selecting Your Parts
Using a trusted AR builder like GunBuilders ensures you receive quality components. Determine the intended use of your AR-15 (e.g., home defense, tactical, long-range shooting) and select compatible parts accordingly.
Step 2: Assembling the Lower Receiver
The lower receiver contains critical firing components and requires careful assembly:
- Install the trigger group and safety selector.
- Attach the buffer tube, stock, and grip.
- Insert the magazine catch and bolt catch.
Step 3: Assembling the Upper Receiver
The upper receiver includes the barrel, bolt carrier group, and handguard:
- Secure the barrel to the upper receiver.
- Install the gas block and gas tube.
- Attach the handguard and muzzle device.
- Insert the bolt carrier group and charging handle.
Step 4: Connecting the Upper and Lower Receivers
Using takedown pins, attach the upper and lower receivers to form a complete rifle.
Step 5: Function Testing and Adjustments
Before using your AR-15, conduct a thorough function test:
- Check the trigger operation.
- Ensure the safety selector functions properly.
- Conduct a dry fire test.
- Make adjustments to the gas system or buffer weight if necessary.
Legal Considerations When Building an AR-15
Building an AR-15 requires compliance with federal and state laws. Here are key legal aspects to consider:
- Serialized vs. 80% Lowers: Serialized lowers must be purchased through an FFL, whereas 80% lowers require additional machining to be legally considered a firearm.
- Assault Weapon Regulations: Some states impose restrictions on barrel length, magazine capacity, and stock configurations.
- Registration Requirements: Certain jurisdictions mandate homemade firearms to be registered.
