The Easy and Affordable Way to Build Firearms: 80 Percent Lower Receivers Explained

Building a firearm from scratch can be a difficult and expensive endeavor. Fortunately, 80 percent lower receivers have made it easier and more affordable than ever to construct a firearm at home. An 80 percent lower is an unfinished piece of aluminum that requires the user to finish machining the firearm frame, allowing the builder to complete the assembly without requiring a Federal Firearms License. With an 80 percent lower, the user can create their own custom firearm from start to finish with minimal effort and expense.

1) What is an 80 Percent Lower Receiver?

An 80 percent lower receiver is an unfinished piece of aluminum that serves as the foundation for building your own firearm. It gets its name from the fact that it is 80 percent complete, requiring the user to finish machining the firearm frame. This allows gun builders to bypass the need for a Federal Firearms License and gives them the opportunity to create a custom firearm from start to finish. With an 80 percent lower, gun enthusiasts can save money, have greater control over the design, and experience the satisfaction of building their own firearm.

2) The Benefits of Using an 80 Percent Lower Kit

Gun builders can enjoy a range of benefits by using an 80 percent lower kit. These kits provide everything needed to complete a firearm build, including all necessary components and tools. By using an 80 percent lower kit, gun builders can save money compared to purchasing a fully assembled firearm. Additionally, these kits offer greater control over the design of the firearm, allowing builders to create a custom weapon that meets their specific needs and preferences. Building a firearm from an 80 percent lower kit also offers a sense of satisfaction and accomplishment, as builders can take pride in creating their own firearm from start to finish.

3) Legal Considerations When Building Your Own Firearm

It is important to be aware of the legal considerations when building your own firearm using an 80 percent lower receiver. While the process itself is legal in most states, it is crucial to familiarize yourself with local, state, and federal laws to ensure compliance. Some jurisdictions may require registration, serialization, or additional background checks for self-built firearms. It is also essential to understand restrictions on firearm modifications, magazine capacity, and other regulations that may vary depending on your location. Staying informed and following the law will help ensure a safe and legal build.

4) Choosing the Right Tools for the Job

When it comes to building your own firearm from an 80 percent lower receiver, choosing the right tools is crucial for a successful build. You’ll want to have a variety of tools on hand, including a drill press, milling machine, or router to complete the machining process. It’s also important to invest in quality cutting tools and drill bits that are designed for working with aluminum. Having the right tools not only makes the process easier, but it also ensures a more precise and professional-looking finish. So take your time, do your research, and invest in the tools that will help you create the firearm of your dreams.
