Understanding the Binary Trigger’s Mechanics
How Binary Triggers Work
At its core, a Binary AR-15 Trigger represents a distinct departure from the conventional semi-automatic trigger system found in most AR-15s. Unlike a standard trigger, which fires one round for each pull of the trigger, the binary trigger operates on a two-stage system. This innovative design allows the firearm to fire a single round when the trigger is pulled (in a “pull” mode) and another single round when the trigger is released (in a “release” mode).
This functionality is achieved through a carefully engineered mechanism. Internally, the trigger utilizes a unique sear and disconnector system. Upon pulling the trigger, the hammer is released, striking the firing pin and igniting the cartridge. On the release stroke, a second sear engages, releasing the hammer again, resulting in a second shot. Essentially, the action is a “pull and release” firing sequence. This is different from a full-auto firearm, because it still requires separate actions to fire each round.
Compared to standard semi-automatic triggers, the Binary AR-15 Trigger offers a significant difference in the rate of fire. While a skilled shooter can achieve a rapid rate of fire with a standard trigger, the binary system inherently facilitates a potentially faster rate. It’s this enhanced rate that makes it so attractive to some and the source of legal scrutiny to others. Understanding the physical components involved in the Binary AR-15 Trigger is key to understanding its functionality. It includes parts that are commonly found on a standard trigger like the trigger shoe, the hammer, and the firing pin, but also incorporates the components that are specific to the binary operation like the unique sears, disconnector, and selector.
The Advantages of Binary Triggers: Beyond the Speed
The allure of the Binary AR-15 Trigger is multifaceted. While increased firing speed is a primary motivator, there are several other advantages to consider.
One of the most obvious benefits is the potential for an increased rate of fire. This can make for a more dynamic and engaging shooting experience for recreational shooters. For those who enjoy speed shooting or rapid-fire exercises, the binary trigger can significantly enhance the experience.
Another advantage lies in its potential for competitive shooting. In certain shooting disciplines, the rapid rate of fire provided by a Binary AR-15 Trigger can be a significant asset. Where allowed by local regulations and competition rules, the trigger’s quickness can translate into faster times and greater accuracy.
Furthermore, the increased rate of fire can also be viewed as a training tool. It can help shooters develop a greater awareness of trigger control and the importance of maintaining proper sight picture during rapid firing.
Potential Drawbacks: Weighing the Considerations
While the benefits of a Binary AR-15 Trigger are enticing, it’s essential to acknowledge the potential drawbacks. These considerations are vital to making an informed decision.
One of the primary drawbacks is the increased cost. Binary AR-15 Triggers typically command a higher price tag than standard triggers, reflecting the advanced engineering and specialized components.
Another critical consideration is the learning curve and the need for practice. Mastering the Binary AR-15 Trigger requires a degree of familiarization and practice. Shooters need to develop a feel for the trigger’s unique action to ensure consistent and accurate shooting. It’s easy to inadvertently “outrun” the trigger, leading to malfunctions if the shooter doesn’t master the nuances.
Furthermore, the trigger’s design inherently allows for more rounds to be fired in a given time, leading to potentially higher ammunition consumption. This is especially important for those with limited budgets or concerns about ammunition availability.
Another factor is the potential for malfunctions. While reputable manufacturers design Binary AR-15 Triggers to be reliable, they are inherently more complex than standard triggers. This means there is a slightly higher probability of malfunctions compared to a more simplistic design. However, quality manufacturers mitigate this with rigorous testing and meticulous manufacturing processes.
Navigating Legal Landscapes: A Crucial Overview
The legal status of Binary AR-15 Triggers is complex and varies significantly depending on location. It’s imperative to understand the relevant laws before considering purchasing or installing one.
Federal law provides the baseline. The Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) has issued rulings and guidance regarding the classification of firearms and trigger mechanisms. The ATF has determined that, in most cases, a Binary AR-15 Trigger does not automatically convert a semi-automatic rifle into a machine gun, provided the trigger operates as a single function. A machine gun is defined as a firearm that shoots, is designed to shoot, or can be readily restored to shoot, more than one shot by a single function of the trigger. However, it is extremely important to remain current and knowledgeable on all of the ATF’s rulings regarding these triggers.
However, the absence of a federal machine gun classification doesn’t mean free rein. State laws vary considerably. Some states have no specific regulations regarding Binary AR-15 Triggers, while others have adopted specific restrictions. Some states outright ban the sale, possession, or use of these triggers.
It’s crucial to research and fully understand the laws in your specific location. This includes federal, state, and any applicable local ordinances. Consult legal professionals if you have any uncertainty. Failing to comply with the laws can lead to severe consequences, including fines, imprisonment, and the loss of firearm rights. Responsible gun ownership starts with a full understanding of the law.
Choosing the Right Trigger: Navigating the Options
If you’ve decided that a Binary AR-15 Trigger aligns with your needs and that it’s legal in your area, the next step is selecting the right one. Numerous brands and models are available, offering varying features and price points.
Begin your search by considering the brand’s reputation and overall reliability. Research the trigger’s reputation by looking at reviews, and reading the experiences of other users. Look for brands that are known for their high-quality manufacturing and robust design.
Another crucial factor is trigger pull weight, both in the “pull” and “release” modes. Consider how this weight aligns with your preferences. For some, a lighter pull weight is desirable, while others prefer a heavier feel. Many Binary AR-15 Triggers offer adjustable pull weights.
Compatibility is also essential. Ensure the trigger is compatible with your AR-15 platform. Most aftermarket triggers are designed to fit the mil-spec standard, but variations exist. Double-check the specifications to ensure the trigger is compatible with your specific receiver and other components.
Another factor is the ease of installation. Some triggers are designed for easy drop-in installation, while others may require more intricate work or professional gunsmithing. Assess your skill level and consider whether you are comfortable installing the trigger yourself.
Lastly, consider your budget. The price of Binary AR-15 Triggers can vary significantly. Set a realistic budget and then research the available options to find the best value for your needs.
When exploring your options, consider leading brands like Franklin Armory and FosTech. These companies have a strong reputation for producing high-quality, reliable Binary AR-15 Triggers.
Researching is the key to making a well-informed decision. Read reviews, watch videos, and compare specifications before purchasing.
Installation and Operation: A Detailed Approach
Installing a Binary AR-15 Trigger requires following detailed instructions. It’s strongly recommended to consult the manufacturer’s instructions, and if you are not comfortable with working on your firearms, have a professional gunsmith complete the installation for you.
Before beginning, prioritize safety. Unload your firearm and confirm that the chamber is empty. Use appropriate safety glasses and work in a well-lit area. Gather the necessary tools, including punches, a hammer, and any other tools specified by the manufacturer. The installation process generally involves removing the existing trigger components and installing the Binary AR-15 Trigger in their place. The exact steps will vary depending on the specific trigger model.
Once the trigger is installed, test it in a safe environment. Check that it fires in both “pull” and “release” modes. Always practice safe gun handling practices, including keeping the muzzle pointed in a safe direction and keeping your finger off the trigger until you are ready to fire.
When using the Binary AR-15 Trigger, develop a feel for the trigger action. Practice controlling the trigger to achieve consistent and accurate firing. Focus on smooth, controlled pulls and releases. This practice is important to minimize malfunctions.
Maintenance and Troubleshooting: Keeping it Running Smoothly
Regular maintenance is essential for ensuring that your Binary AR-15 Trigger functions reliably.
Develop a regular cleaning schedule. Disassemble the trigger components (if your trigger is designed to be disassembled) and clean them with a suitable gun cleaning solvent. Remove any dirt or debris. Lubricate the trigger parts with a high-quality gun oil, paying attention to the pivot points and contact surfaces.
In addition to cleaning, inspect the trigger components regularly for signs of wear or damage. If you notice any issues, seek professional assistance from a qualified gunsmith.
Despite diligent care, malfunctions can sometimes occur. Common issues include failure to fire, light primer strikes, and double feeding. If the trigger fails to fire, it could be due to several reasons. Ensure the firing pin is functioning correctly and is not being obstructed. If you notice light primer strikes, this may be caused by issues with the hammer spring or the firing pin itself. Double feeding is a result of improper ejection of the spent casings, and a qualified gunsmith should address that issue.
While some minor troubleshooting can be performed at home, seek professional help for more complex issues. Do not attempt to repair a trigger if you are not experienced with firearms.
Alternatives to the Binary Trigger: Considering the Options
The Binary AR-15 Trigger isn’t the only way to potentially increase the firing rate of an AR-15. Several alternative methods are available.
One increasingly uncommon option is the bump stock. Bump stocks utilize the recoil of the firearm to rapidly cycle the trigger, leading to an increased rate of fire. However, these devices are heavily restricted by the ATF, with many states having bans.
Other aftermarket triggers, such as those with a very short reset or light pull weight, can help you achieve a faster rate of fire. While not offering the “two shots per trigger pull” of a Binary AR-15 Trigger, these triggers can still enhance the speed of the shooting process.
Finally, skillful shooters can often achieve a rapid rate of fire with standard triggers through practice and proper technique.
The best choice for you depends on your individual preferences, shooting goals, and legal constraints.
Conclusion: The Responsibility of Ownership
The Binary AR-15 Trigger presents a unique proposition for firearm enthusiasts. Its enhanced firing speed and unique operation can offer both recreational enjoyment and, in some circumstances, competitive advantages.
