What is an 80 Percent Lower?

The term "80 percent lower" refers to a partially finished lower receiver of a firearm, typically an AR-15 or AR-10 platform. This component is not classified as a firearm because it has not yet been completed to the point of being operational. The concept behind the 80 percent lower is that it allows individuals to engage in the process of building their own firearms without the need for a federal firearm license (FFL).

To further clarify, an 80 percent lower is essentially a block of material that has been pre-machined to a certain extent, but it still requires significant work before it can function as a complete lower receiver. This allows hobbyists to customize their firearms while adhering to legal regulations.

Legal Implications of the 80 Percent Lower

Understanding the legal landscape surrounding 80 percent lowers is crucial for anyone considering building their own firearm. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has laid out specific guidelines regarding what constitutes a firearm. According to these regulations, a lower receiver is considered a firearm when it is fully completed and can house the necessary components to operate.

Since an 80 percent lower is not classified as a firearm, individuals can purchase and possess it without the need for background checks or permits. However, once an individual completes the lower receiver, it is legally considered a firearm, and they must adhere to all applicable laws regarding firearm ownership and registration.

Components of an 80 Percent Lower

The primary component of an 80 percent lower is the lower receiver itself. This part houses several critical elements of a firearm, including the trigger assembly, magazine well, and stock attachment. Here are some key components to consider:

Lower Receiver: The main body that contains the trigger and magazine release.
Trigger Assembly: The mechanism that activates the firing pin.
Buffer Tube: A tube that houses the buffer spring and helps absorb recoil.
Stock: The shoulder rest that provides stability while aiming.

Building Your Own Firearm: Step-by-Step

Building a firearm from an 80 percent lower can be a rewarding experience. Here’s a simplified step-by-step process:

Gather Tools: Ensure you have the necessary tools, such as a drill press, router, and various drill bits.
Complete the Lower: Follow instructions to complete the machining of the lower receiver.
Assemble Components: Install the trigger assembly, buffer tube, and stock.
Test Functionality: Ensure all parts are functioning correctly before using the firearm.

Advantages of Using an 80 Percent Lower

There are several advantages associated with using an 80 percent lower to build your own firearm:

Customization: Allows for personalized features and modifications.
Cost-Effectiveness: Often more affordable than purchasing a fully assembled firearm.
Legal Flexibility: Avoids the need for FFL in the initial stages of construction.
Skill Development: Enhances mechanical skills and knowledge of firearms.

Challenges and Considerations

While building an 80 percent lower can be enjoyable, it’s essential to consider potential challenges:

Complexity: Machining and assembly can be complicated and requires precision.
Legal Compliance: You must understand and comply with local and federal laws.
Safety Risks: Improper assembly can result in malfunctions and safety hazards.

Safety and Responsibility

With great power comes great responsibility. When building your own firearm, safety should always be a top priority. Here are some safety tips:

Wear Protective Gear: Always use safety glasses and ear protection while machining.
Follow Instructions: Adhere to all guidelines provided with your 80 percent lower.
Practice Safe Handling: Treat all firearms as if they are loaded and always point them in a safe direction.

Conclusion
