Defining the Partially Completed Receiver
Understanding the fundamental concepts surrounding 80% lowers is crucial before diving into the specifics of an Aluminum 80 Glock Lower. Unlike a completed lower receiver, which is fully machined and ready to accept parts, an 80% lower is a partially finished component. It’s been intentionally left incomplete to comply with federal regulations. The unfinished nature means that the purchaser will need to perform some final machining or finishing operations to make the lower functional.
The significance of the “80%” designation lies in the legal definition of a firearm. Federal regulations define a firearm as a complete receiver, effectively regulating its production and sale. By leaving certain operations unfinished, these lowers fall outside that definition, which historically has meant they could be purchased without requiring a background check in many jurisdictions. It is crucial to reiterate the importance of understanding the laws in your specific state and locality because they vary widely. Some areas might have stricter regulations, while others may have none.
The material of choice for an Aluminum 80 Glock Lower is typically high-quality aluminum alloys, such as 7075-T6 or 6061-T6. These materials are favored for their exceptional strength-to-weight ratio, corrosion resistance, and machinability. The use of aluminum also contributes to the overall durability and longevity of the final product. When selecting an Aluminum 80 Glock Lower, consider the specific grade of aluminum used, as it can influence performance and durability.
Compatibility is paramount. The Aluminum 80 Glock Lower is designed to accept standard Glock components, meaning it is compatible with Glock-style slides, barrels, and parts kits. This allows builders to leverage the vast aftermarket support and interchangeability of parts that have made Glock firearms so popular.
