What Are 80 Percent Arms?
80 percent arms are firearm receivers that are classified as incomplete, meaning they are not yet considered functional firearms under federal law. These receivers are typically 80% finished, with certain machining steps left undone, such as drilling trigger pinholes or milling fire control cavities. The term "80 percent" refers to the level of completion of the receiver.
This concept allows individuals to purchase these unfinished parts without the need for a background check or federal firearm license (FFL) since they do not meet the legal definition of a firearm. However, buyers must complete the remaining 20% of machining themselves to turn the receiver into a functional firearm. This process requires specific tools, precision, and adherence to legal guidelines.
Why Are They Popular?
The appeal of 80 percent arms lies in their versatility and accessibility. They offer firearm enthusiasts the chance to build a customized weapon while bypassing some of the restrictions associated with purchasing a fully assembled firearm. Additionally, they provide a hands-on experience, allowing individuals to understand the inner workings of their firearm.
Are They Safe?
When completed correctly, 80 percent arms are just as safe as commercially manufactured firearms. However, the responsibility lies with the builder to ensure that the final product meets safety standards and functions as intended. This means following proper machining techniques, using quality materials, and adhering to all legal requirements.
Legal Aspects and Regulations
Understanding the legal framework surrounding 80 percent arms is crucial for anyone interested in this DIY firearm option. While federal law permits the purchase and completion of these parts, state and local regulations may vary. It is the responsibility of the builder to ensure compliance with all applicable laws.
What Does Federal Law Say?
Under U.S. federal law, 80 percent arms are not considered firearms since they are incomplete and non-functional. As a result, they do not require serialization, a background check, or transfer through a licensed dealer. However, once completed, the receiver becomes a functional firearm and is subject to all laws governing firearm ownership.
State and Local Restrictions
Some states have enacted stricter regulations regarding 80 percent arms. For example, California requires completed receivers to be serialized and registered with the state Department of Justice. Other states, like New Jersey and New York, have outright banned the possession of 80 percent arms. It is essential to research and understand the laws in your area before proceeding with a project.
How Do You Build 80 Percent Arms?
