Building firearms at home, particularly through the use of 80% lower receivers, is a topic that involves a mix of technical expertise, legal awareness, and safety considerations. This article aims to provide a comprehensive overview of the process, focusing on the key aspects one must consider when undertaking such a project.
Understanding 80% Lowers
An 80% lower receiver, often simply referred to as an “80 lower,” is a piece of firearm component that is not yet fully machined into a complete lower receiver. Because it is not considered a firearm by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), it can be purchased without the need for a Federal Firearms License (FFL) or a background check. The term “80%” indicates that the lower is 80% complete, requiring the purchaser to finish the remaining 20% of the machining work.
Legality and Compliance
Before embarking on any project involving 80% lowers, it is crucial to be well-informed about the legal implications. Laws regarding the manufacture of firearms vary widely across different states and countries. In some places, it may be entirely legal to manufacture a gun for personal use without a serial number, while in others, there are strict regulations that must be followed. Always consult local and federal laws to ensure full compliance.
The Process of Building
The process of turning an 80% lower into a functional firearm component is a task that requires precision and technical skill. Typically, the remaining 20% of the work involves drilling holes and milling out sections of the lower. This can be done using a variety of tools, including a drill press, a milling machine, or specialized jigs designed for this purpose.
Safety and Responsibility
Safety is paramount when working with tools and firearms. Proper eye and ear protection should be worn at all times during the machining process. Additionally, once the firearm is complete, it is the builder’s responsibility to use and store it safely, in accordance with all applicable laws and regulations.
Tools and Materials
To successfully grab an 80% lower and complete it, you will need a range of tools and materials. This includes the 80% lower itself, the necessary machining tools, and the additional parts required to assemble a complete firearm, such as a trigger assembly, stock, and barrel. It is important to purchase high-quality materials and tools to ensure the reliability and safety of the finished firearm.
Skill Level and Learning Curve
Building a firearm from an 80% lower is not a project for beginners. It requires a significant amount of technical skill, precision, and patience. However, for those with a background in machining or gunsmithing, it can be a rewarding project. There are numerous resources available, including online forums, instructional videos, and community workshops, that can help guide you through the process.
Conclusion
Building a gun from an 80% lower is a challenging yet rewarding project for those with the right skills and knowledge. It is essential to approach this task with a deep respect for the law, a commitment to safety, and a thorough understanding of the technical requirements. Whether you’re a seasoned gunsmith or a hobbyist looking to expand your skills, working with an 80% lower offers a unique opportunity to build a firearm that is truly your own.
