7 Essential Tips For Buying An 80 Lower Receiver

When it comes to building your own firearm, one of the most critical components you’ll need is an 80 lower receiver. Not only is this part essential for the legality of your build, but it’s also the foundation on which you’ll build your custom firearm. Whether you're a seasoned gunsmith or a first-time builder, understanding how to choose the right 80 lower receiver can make or break your project. In this blog post, we will delve into seven essential tips for buying an 80 lower receiver to ensure you make the best choice for your needs. 💡

1. Understand the Legality

Before diving into purchasing your 80 lower receiver, it’s crucial to be aware of the legal implications surrounding it. The term "80% lower" refers to the fact that this part is not considered a firearm under federal law. However, laws can vary significantly from state to state. Here are a few key points to remember:

• Research Your State Laws: Each state has different regulations regarding the manufacturing and ownership of firearms. Some states may require you to register your 80 lower, while others prohibit them altogether.
• Stay Updated: Laws can change, so regularly check for updates in legislation that could affect your purchase.

2. Choose the Right Material

The material of your 80 lower receiver affects its durability, weight, and overall performance. Common materials include:

• Aluminum: Lightweight and strong, aluminum receivers are popular among builders. They can also come anodized for extra protection against wear and corrosion.
• Polymer: While generally less expensive and lighter, polymer receivers may not offer the same strength and durability as aluminum. However, they can be a good option for those looking for a budget-friendly build.

Consider your intended use and choose the material that fits your needs best.

3. Check for Compatibility

Not all lower receivers are created equal; they come with different features and specifications. Here are a few compatibility tips:

• Firearm Type: Ensure that the 80 lower receiver you select is compatible with the upper receiver you plan to use, whether it's AR-15, AR-10, or another platform.
• Parts Compatibility: Check that the internal components, such as the trigger assembly, pistol grip, and buffer tube, match the specifications of your lower receiver.

4. Assess Build Quality

Quality matters when it comes to firearms. Here’s what to look for:

• Precision Machining: Inspect the machining process of the lower receiver. Precision cuts will allow for smoother fitment and operation.
• Material Finish: Look for lower receivers with a protective coating or finish. A good finish will help prevent rust and other wear over time.

Consider reading reviews from other users to gauge the build quality of a specific lower receiver brand.

5. Evaluate the Price

While it's tempting to go for the cheapest option, consider your investment in quality:

• Budgeting: Determine a reasonable budget for your lower receiver before you start shopping. A good rule of thumb is to spend a bit more for quality, as this can affect your build's overall performance and longevity.
• Compare Prices: Take the time to compare prices across different retailers. Often, you can find deals or discounts, especially if you’re willing to buy in bulk.

6. Consider Future Customization

A big draw of building your own firearm is the ability to customize it to your preferences. When choosing an 80 lower receiver, think ahead:

• Modularity: Some lower receivers come with added features like ambidextrous controls or integrated trigger guards, which can provide versatility for future upgrades.
• Aftermarket Support: Check for the availability of aftermarket accessories that can enhance your build down the line.

7. Purchase from Reputable Sellers

Finally, always buy from established and trusted suppliers. Here’s why:

• Reputation and Reviews: Look for suppliers with a solid reputation and positive reviews from previous customers.
• Customer Support: A reputable seller will offer better customer support and return policies in case you encounter any issues with your lower receiver.

Common Mistakes to Avoid

Even seasoned builders can make mistakes when purchasing an 80 lower receiver. Here are a few to avoid:

• Failing to Research: Skipping the research phase can lead to a lot of headaches down the line. Always do your homework first.
• Ignoring Compatibility: Ensure that all parts are compatible to avoid assembling a firearm that won’t function correctly.
• Not Inspecting the Item: When buying in person, thoroughly inspect the receiver before purchasing. If buying online, check the return policy.

Troubleshooting Issues

If you encounter issues with your 80 lower receiver, consider these troubleshooting steps:

• Check Assembly Directions: Sometimes, problems arise simply from not following the assembly instructions correctly.
• Inspect for Damage: Look for any signs of physical damage, such as cracks or severe scratches, which might affect performance.
• Reach Out for Help: If you’re struggling, consult with more experienced builders or reach out to the manufacturer for assistance.
