What Are 80 Percent Arms?
At their most basic level, 80 percent arms are firearm frames or receivers that are not fully completed. These components are typically sold in an unfinished state, requiring the purchaser to perform additional machining or assembly to make them functional. The term "80 percent" is a general descriptor, indicating that the component is close to being complete but still requires significant work to be considered a firearm under federal law. These unfinished receivers are often made from materials like aluminum or polymer, and they are designed to be compatible with various firearm models.
So, why are they called "80 percent arms"? The term is somewhat misleading because there is no official legal definition of what constitutes an 80 percent receiver. Instead, it refers to the idea that the component is unfinished enough to avoid being classified as a firearm under the Gun Control Act of 1968. This legal gray area has made 80 percent arms a popular choice for individuals who want to build their own firearms without going through the traditional channels of purchasing a fully assembled weapon.
But how do these components differ from fully assembled firearms? The key distinction lies in their level of completion. A fully assembled firearm is subject to strict regulations, including background checks, serial number requirements, and registration in some jurisdictions. In contrast, 80 percent arms are sold as unfinished products, which means they are not subject to the same level of scrutiny. This has led to concerns about their potential misuse and the challenges they pose for law enforcement.
How Are 80 Percent Arms Made?
The manufacturing process for 80 percent arms is a fascinating blend of precision engineering and DIY craftsmanship. These components are typically produced using advanced machining techniques, such as CNC (Computer Numerical Control) milling. CNC machines allow manufacturers to create highly accurate and consistent parts, ensuring that the unfinished receivers are compatible with a wide range of firearm models. The process begins with raw materials, such as aluminum or polymer, which are cut and shaped into the basic form of a firearm receiver.
Once the initial machining is complete, the components are left in an unfinished state. This means that certain critical features, such as the fire control cavity or the trigger slot, are not fully machined. The purchaser is then responsible for completing these features using tools like a drill press, Dremel, or a specialized jig. This process requires a certain level of technical skill, but many manufacturers provide detailed instructions and toolkits to make the process more accessible to hobbyists.
What makes this process so appealing to DIY enthusiasts? For one, it allows individuals to customize their firearms to a degree that is not possible with off-the-shelf models. By completing the machining process themselves, users can tailor the firearm to their specific preferences, whether that means adjusting the ergonomics, adding custom features, or simply enjoying the satisfaction of building something with their own hands. However, this DIY approach also raises important questions about safety, legality, and accountability.

Are 80 Percent Arms Legal? What You Need to Know
One of the most frequently asked questions about 80 percent arms is whether they are legal. The short answer is that the legality of these components depends on a variety of factors, including federal, state, and local laws. Under federal law, unfinished receivers are not classified as firearms, which means they are not subject to the same regulations as fully assembled weapons. This includes background checks, serial number requirements, and registration. However, this legal framework is not uniform across all jurisdictions.
What Are the Federal Regulations?
At the federal level, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) regulates firearms under the Gun Control Act of 1968. According to ATF guidelines, a firearm receiver must be "readily convertible" into a functional firearm to be classified as such. Because 80 percent arms are not fully machined, they do not meet this criterion and are therefore not subject to federal firearm regulations. This has allowed manufacturers to sell these components without the same level of oversight as fully assembled firearms.
What About State and Local Laws?
While federal law provides a baseline for the regulation of 80 percent arms, state and local governments have the authority to impose additional restrictions. Some states, such as California and New York, have enacted laws specifically targeting unfinished receivers. These laws often require individuals to undergo background checks, register their completed firearms, or even prohibit the sale of 80 percent arms altogether. As a result, it is essential for buyers to familiarize themselves with the laws in their specific jurisdiction before purchasing or assembling an 80 percent arm.
Despite these regulations, the legal landscape surrounding 80 percent arms remains complex and evolving. Lawmakers and advocacy groups continue to debate the implications of these components, particularly in light of concerns about gun violence and public safety. As such, anyone considering purchasing or assembling an 80 percent arm should stay informed about the latest developments in firearm legislation.
