80 lowers," also known as "80% lowers" or "unfinished receivers," are firearm components that are partially completed, requiring additional work to transform them into functional firearms. These lower receivers typically lack certain key features, such as the fire control group pocket, trigger slot, and drill holes, which must be machined or finished by the builder. This process allows individuals to legally build their own firearms without the need for a license or serial number. 80 lowers have gained popularity among gun enthusiasts for their customizability and the satisfaction of creating a personalized firearm.
