Anderson Manufacturing has become a prominent name in the firearms industry, particularly known for its 80% lower receivers. These unfinished receivers offer a unique pathway to building your own AR-15 style firearms, appealing to both enthusiasts and experienced builders. This guide delves into the specifics of Anderson Manufacturing 80% lowers, exploring their features, benefits, and considerations before purchasing.
Understanding Anderson Manufacturing 80% Lowers
An 80% lower receiver is a partially machined receiver that requires further processing to become a functional firearm lower. Unlike a complete lower receiver, the 80% version lacks critical components, including the fire control group pocket and trigger pin holes. This incompletion allows it to avoid certain regulations surrounding the sale and ownership of firearms in various jurisdictions. It's crucial to understand the laws in your area before purchasing and completing an 80% lower.
Anderson Manufacturing's 80% lowers are typically made from high-quality aluminum alloys, chosen for their durability and strength. The company offers a variety of finishes, including anodized black, and sometimes even offers specialized options. The receivers are designed to be compatible with standard AR-15 parts, ensuring builders have access to a wide range of aftermarket components.
Benefits of Choosing Anderson Manufacturing 80% Lowers
Several factors contribute to the popularity of Anderson Manufacturing's 80% lowers:
- Cost-Effectiveness: Compared to complete lower receivers, 80% lowers often offer significant cost savings, especially appealing to budget-conscious builders.
- Customization: Building your own AR-15 from an 80% lower allows for extensive customization. You can choose specific components and finishes to tailor your firearm to your exact preferences.
- Compliance (with caveats): The unfinished nature of the receiver allows for purchasing and possession in areas with stricter firearms regulations, though it's important to always verify local laws.
- Satisfaction: The satisfaction derived from building your own firearm is a key motivator for many.
Considerations Before Purchasing an Anderson Manufacturing 80% Lower
Before embarking on this project, consider the following:
- Legal Implications: Thoroughly research and understand the federal, state, and local laws concerning the manufacture and ownership of firearms. Failure to comply can result in severe legal consequences. Always check your local and state laws before making a purchase.
- Machining Requirements: Completing an 80% lower requires specialized tools and knowledge. Improper machining can result in a malfunctioning or unsafe firearm.
- Safety Precautions: Building a firearm requires careful attention to safety. Proper handling of tools and materials is essential to avoid accidents.
- Jigs and Fixtures: To ensure accurate and safe completion, you'll need the right jig and tooling; selecting the proper jig for your chosen machining process (e.g., milling) is critical.
The Build Process: An Overview
The process of completing an Anderson Manufacturing 80% lower generally involves several steps:
- Acquiring Necessary Tools and Equipment: This includes the jig, end mill(s), and other relevant equipment.
- Securing the Jig and Lower: Properly securing the 80% lower in the jig is paramount for precise machining.
- Machining the Receiver: This involves using appropriate tools and techniques to create the necessary cuts and holes.
- Inspection and Quality Control: Before installation of parts, inspect the completed receiver for any defects or inconsistencies.
- Assembly: After the machining process is complete, carefully assemble the lower receiver with other AR-15 components.
Note: This is a simplified overview. Detailed instructions and videos are available online from various sources, but always prioritize safety.
Conclusion
Anderson Manufacturing 80% lowers provide an accessible entry point for individuals interested in building their own AR-15 style firearms. However, it is imperative to understand and fully comply with all applicable laws and regulations. Thorough research, preparation, and attention to safety are crucial throughout the entire process. Always prioritize safety and legal compliance when working with firearms and firearm components. Remember to consult with experienced builders or gunsmiths if you have any doubts or questions throughout the build process.
