The world of AR-15 builds is constantly evolving, and one component that has sparked considerable interest is the binary trigger. This guide delves into the specifics of the Franklin Armory binary trigger, particularly its use with 80% lower receivers, addressing legality, functionality, and potential concerns.
Understanding the Franklin Armory Binary Trigger
The Franklin Armory binary trigger is a unique firearm accessory that operates differently from standard triggers. Unlike traditional triggers that fire only when the trigger is pulled and released, a binary trigger fires once when the trigger is pulled and again when it's released. This "two-shot" functionality significantly increases the rate of fire. This increased rate of fire is the primary draw for many users, but it also necessitates a high level of training and responsible gun handling.
Important Note: Legality surrounding binary triggers varies widely by state and jurisdiction. It's absolutely crucial to research and understand the laws in your area before purchasing or using a binary trigger. Failure to comply with local regulations can result in serious legal consequences. This guide does not provide legal advice; consult with legal counsel for clarification on applicable laws.
Binary Triggers and 80% Lower Receivers: The Build Process
Building an AR-15 pistol or rifle from an 80% lower receiver involves completing the manufacturing process of the receiver. This often involves machining or other modifications to transform the unfinished receiver into a functional firearm part. Installing a Franklin Armory binary trigger within an 80% lower requires careful attention to detail and precision. The process is generally considered more technically demanding than installing a standard trigger group, requiring tools, knowledge, and proficiency. Improper installation can lead to malfunctions or safety hazards.
Steps Involved (General Overview):
- Completion of the 80% Lower: This step involves the finishing of the receiver to the point it’s compatible with all other components, typically using a jig and appropriate tools.
- Trigger Group Installation: Carefully installing the Franklin Armory binary trigger group into the completed lower receiver. This requires a thorough understanding of the trigger assembly and its components.
- Function Testing: After installation, the trigger assembly must be meticulously tested to ensure proper and safe functionality. This should be done in a controlled environment with appropriate safety measures.
Considerations Before Purchasing and Installation
Several factors need consideration before acquiring and installing a Franklin Armory binary trigger into an 80% lower receiver.
Legal Compliance:
- Federal Laws: The legality of binary triggers at the federal level is complex and constantly evolving. Thorough research is necessary.
- State Laws: State laws vary significantly. Some states have outright banned binary triggers while others have restrictions on their use or sale. Check your local laws and regulations before proceeding.
Safety Precautions:
- Training: Using a binary trigger demands extensive firearms training and practice to ensure safe handling and operation. The increased rate of fire requires advanced skills and discipline.
- Proper Installation: Incorrect installation can lead to malfunctions, jamming, or even accidental discharge. Seek guidance from experienced gunsmiths if necessary.
- Maintenance: Regular cleaning and maintenance are crucial for optimal performance and safety.
Functionality and Reliability:
- Compatibility: Ensure the binary trigger is compatible with your specific 80% lower receiver and other components.
- Reliability: While Franklin Armory produces quality products, like any mechanical device, malfunctions are possible. Regular checks are recommended.
Conclusion
The Franklin Armory binary trigger offers a unique shooting experience, but it comes with responsibilities. Before considering such a build, comprehensive research on legal aspects and meticulous attention to safety are paramount. The increased rate of fire necessitates a higher level of training and skill. Always prioritize safe gun handling practices and adhere to all applicable laws and regulations. Remember, responsible gun ownership is crucial. Consult with experts and experienced gunsmiths throughout the process for guidance and assistance.
