What is an 80 Percent Lower?
An 80 Percent Lower is a firearm receiver that is only 80% complete, meaning it’s not considered a firearm by the ATF yet. These lower receivers are typically made from aluminum, polymer, or other materials, and they require some additional milling or drilling to become a functioning part of a rifle or handgun. Many gun enthusiasts enjoy building their own firearm from scratch, and these 80 percent lowers provide a great opportunity to do so legally and without the need for an FFL transfer.
However, it’s essential to understand state and federal laws, as well as the specific guidelines for machining these lower receivers. Companies that sell 80 percent lowers often offer detailed instructions and video tutorials on how to complete the process. By understanding the laws and best practices for building your own firearm, you can enjoy the satisfaction of creating your own weapon while staying on the right side of the law.
Why Choose an 80 Percent Lower?
If you’re interested in building your own firearm, an 80 percent lower might be the way to go. These unfinished lower receivers require some drilling and milling to turn them into functional parts, but the result is a reliable and durable gun that you’ve built with your own hands. One of the reasons for choosing an 80 percent lower is the satisfaction of taking control of the build process and creating a unique firearm.
Another advantage is the lower cost compared to buying a pre-built gun, especially if you already have the necessary tools. Of course, if you’re new to gun building, the process may seem daunting, but there are plenty of resources available to help you through it. Overall, using an 80 percent lower can give you a deeper understanding of how your firearm works and the satisfaction of creating something yourself.
So, give it a try and see what you can build.
The Legal Implications of 80 Percent Lowers
If you’re a gun enthusiast or someone who enjoys DIY projects, you may have heard of 80 percent lowers. These are essentially incomplete firearm receivers that can be easily completed with a few basic tools. However, one major consideration when it comes to building a firearm from an 80 percent lower is the legal implications.
While it’s legal to build your own firearm, there are certain restrictions in place. For example, you can’t sell a firearm built from an 80 percent lower without obtaining the proper license. Additionally, if you build a firearm that violates local or federal laws, you could face serious consequences.
It’s crucial to do your research and understand the laws surrounding 80 percent lowers and firearms in general before embarking on a DIY project. Overall, while building a firearm from an 80 percent lower can be a fascinating project, it’s important to proceed with caution and abide by all applicable laws.
What Tools Do You Need for an 80 Percent Lower?
If you plan on completing an 80 percent lower, you will need a few tools to get the job done. While a drill press may seem like a necessity, it is not always required. The most essential tool you will need is a drill, which can be hand-operated or mounted to a workbench.
You will also need a drill bit set that includes sizes appropriate for your specific lower receiver. Additionally, a vise is recommended to securely hold your lower in place during drilling. Other tools that may come in handy include a punch set for removing pins, an end mill for milling out the fire control cavity, and a torque wrench to properly tighten the buffer tube.
While a drill press offers added precision and power, it is not completely necessary for completing an 80 percent lower. With the proper tools and attention to detail, you can successfully complete your lower receiver project without breaking the bank on a drill press.
The Basics: Drilling and Milling
When it comes to completing an 80 percent lower, you’ll need a few tools to properly drill and mill the receiver. The most important tool you’ll need is a drill press, which will allow you to drill the necessary holes in the lower receiver. You’ll also need an end mill bit, which will help you mill out the remaining material from the trigger pocket.
Additionally, a vise and fixture is recommended for holding the lower receiver in place during the drilling and milling process. Other tools you may need include safety glasses, a workbench, a measuring tape, and a lubricant. By having these tools on hand, you’ll be well-prepared to tackle your own 80 percent lower project.
The Importance of Accuracy and Precision
When it comes to finishing an 80% lower, accuracy and precision are key. To ensure that your build is successful, you will need a few essential tools. Firstly, a drill press is necessary to create the required holes in the receiver.
It’s important to invest in a quality drill press as it will allow you to accurately position the lower and ensure clean, precise cuts. Additionally, a router jig is needed to guide the drill bit and maintain the correct angle during drilling. Without this tool, your build may be off by a few degrees which can affect the function of your firearm.
Another essential tool is a vise to securely hold the receiver during the milling process. This will minimize the risk of any mistakes due to movement or slippage. Lastly, a digital caliper is essential for accurate measurements, allowing you to ensure that your build is within the required tolerances.
Investing in the right tools will not only ensure that your build is successful but will also allow you to achieve a high level of precision and accuracy with your 80% lower.
Alternative Tool Options
When building an 80 percent lower, having the right tools is essential to ensure a successful outcome. Some alternative tool options that you may want to consider for this type of project include drill presses with a vice or jig, a router with a jig, a finishing jig with a handheld drill, a barrel nut wrench, and an armorers wrench for tightening the castle nut. Of course, the specific tools you’ll need will depend on the type of lower you’re working with and the techniques you’re using, but having a complete tool kit will make the process much easier.
Additionally, investing in high-quality tools will help you achieve a more precise finish and improve the overall durability and functionality of your firearm. By having the right tools and taking the time to do things correctly, you can create a reliable firearm that you’ll be proud to own and use for years to come.
Should You Invest in a Drill Press for Your 80 Percent Lower?
