Build Your Own: Reviewing the Best 80% Lowers for Your Next Project
80% Lowers: Top 3 Best Choices for Your Project in 2024
Introduction
Looking to build your own firearm and stumbled upon the term 80 lowers? Let’s break it down.
80% lowers are unfinished lower receivers for AR-style rifles and pistols. They are called “80%” because they are only 80% complete. This means they aren’t considered firearms by the ATF and can be bought without a background check in most states.
Key Points:
– What are 80 lowers? Partially finished lower receivers for firearms.
– Why use them? Customization, privacy, and a rewarding DIY project.
– Important to know: Not all states allow them. Know your local laws.
80% lowers provide firearm enthusiasts the opportunity to build a customized rifle or pistol suited to their personal preferences. You can choose from different materials, finishes, and even add unique engravings to make your firearm truly one-of-a-kind.
But remember, completing an 80% lower receiver involves some machining. You’ll need tools like a drill and router, and a jig to guide the process. While it’s a rewarding experience, it’s important to understand the legal intricacies before you start.
What is an 80% Lower Receiver?
An 80% lower receiver is a partially completed firearm receiver that requires additional machining to be functional. As the name suggests, it’s about 80% finished, leaving the remaining 20% for the builder to complete. This includes tasks like drilling holes and milling out internal cavities.
Legal Status
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) does not classify an 80% lower as a firearm. This means it can be sold without a serial number or a background check. However, once you complete the machining process, it becomes a firearm under federal law, and all firearm regulations apply.
ATF Guidelines
According to the ATF’s guidelines, an 80% lower is not considered a firearm because it lacks certain features. For instance, it doesn’t have the necessary holes drilled for the trigger or hammer pins, and the fire control cavity is not milled out. These features are essential for the receiver to function as a firearm.
Key Point: Once you complete the remaining 20% of the machining process, the lower receiver becomes a firearm. At this point, federal laws on firearms apply, including serialization requirements if you plan to sell or transfer the completed firearm.
Important Note: Always check your local and state laws before purchasing or completing an 80% lower. Some states, like California and New York, have stricter regulations that may require serialization even for personal builds.
Why Choose an 80% Lower?
Building your own receiver from an 80% lower allows for a high level of customization. You can choose your own materials, finishes, and even add personalized engravings. It’s a way to create a firearm that is uniquely yours while also gaining a deeper understanding of how it functions.
Next, we will discuss the legal considerations you need to keep in mind when dealing with 80% lowers.
Legal Considerations for 80% Lowers
When working with 80% lowers, it’s crucial to understand the legal landscape. Both federal and state laws apply, and they can vary significantly.
Are 80% Lowers Legal in Your State?
Federal Law: Under federal law, an 80% lower is not considered a firearm. This means it can be bought and sold without a serial number or background check. However, once you complete the remaining 20% of the machining process, it becomes a firearm and must comply with federal laws.
State Laws: While federal law provides a baseline, state laws can be more restrictive. Here are some examples:
- California: Requires serialization of 80% lowers, even for personal builds.
- Colorado: Cities like Boulder and Denver have their own regulations that may restrict or ban 80% lowers.
- Connecticut, Hawaii, Illinois, Maryland, New Jersey, New York, Rhode Island, Washington, and Washington D.C.: These states and districts have restrictions or outright bans on 80% lowers.
Always check your specific state and local laws to ensure compliance.
Do 80% Lowers Need to Be Serialized?
Federal Regulations: Federally, you are not required to serialize an 80% lower for personal use. However, if you plan to transfer, sell, or distribute the completed firearm, you must serialize it according to federal law.
State Exceptions: Some states have stricter serialization requirements. For instance:
- California: Requires serialization even for personal builds.
- Other States: States like Connecticut and New Jersey have their own serialization requirements.
Key Point: If you use a licensed firearms manufacturer to complete your 80% lower, they will handle serialization for you.
Understanding these legal considerations is essential before starting your build. Next, we’ll delve into the benefits of building with 80% lowers.
Benefits of Building with 80% Lowers
Why Choose an 80% Lower?
Customization
Building your own firearm from an 80% lower allows for unparalleled customization. You can add your personalized logo, choose custom colors and finishes, and even create a unique serial number. This level of customization ensures that your firearm is truly one-of-a-kind.
Imagine having a rifle that not only performs well but also reflects your personal style. Whether you prefer a sleek black finish or a vibrant cerakote, the choice is entirely yours.
Cost-effectiveness
One of the most compelling reasons to opt for an 80% lower is cost-effectiveness. By purchasing an unfinished receiver, you can save significantly on manufacturing costs and avoid the “brand tax” that many gun makers charge. Additionally, you won’t have to pay the taxes and fees typically associated with purchasing completed firearms.
For example, the prices for AR-15 80% lowers at Daytona Tactical range from $89.97 to $329.94, depending on the model and finish. This can be much cheaper than buying a completed firearm, allowing you to invest more in other high-quality parts for your build.
Privacy
Privacy is another significant advantage. Since 80% lowers are not considered firearms by the ATF, they come without serial numbers. This means you can purchase one without the need for background checks or filling out FFL paperwork.
This allows you to build your firearm discreetly, avoiding any invasions of privacy. Where data privacy is a growing concern, this can be a huge benefit.
Control
Starting with a blank receiver gives you complete control over your build. You decide which parts to install, allowing for a truly custom firearm. Whether you want a specific trigger, a particular grip, or a unique stock, an 80% lower gives you the freedom to choose every component.
No FFL Required
Another advantage is that you don’t need a Federal Firearms License (FFL) to purchase an 80% lower. This simplifies the buying process and makes it more accessible for hobbyists and DIY enthusiasts.
Direct Shipping
Since 80% lowers are not classified as firearms, they can be shipped directly to your home. This is a huge convenience, especially if you live far from a gun store. It also means you can shop around for the best deals online without worrying about FFL transfer fees.
These benefits make building with 80% lowers an attractive option for many firearm enthusiasts. Next, we’ll guide you through the process of completing an 80% lower, including the tools you’ll need and the steps involved.
