Understanding the Binary Trigger Phenomenon
What is a Binary Trigger?
Before we get into the specifics of the Fostech Binary Trigger, let’s clarify what a binary trigger actually *is*. At its core, a binary trigger is designed to fire a single round both when you pull the trigger *and* when you release it. Unlike a standard semi-automatic trigger that only fires when pulled, the binary trigger effectively doubles your rate of fire (in theory, and with practice). Think of it as a “two-way” trigger.
The concept is relatively simple: when you pull the trigger, the firearm fires. When you release the trigger, another round is discharged. This creates a distinctive shooting experience. This is *not* the same as full-auto fire. With a binary trigger, you still need to consciously release the trigger for each additional round. The rate of fire is still dictated by your trigger control, as opposed to the continuous firing of a machine gun.
The core advantage of a binary trigger is the potential for a significantly increased rate of fire compared to a standard trigger. This faster rate can be both fun and can be advantageous for certain training exercises or competitive shooting styles.
However, it’s critically important to remember the legal considerations surrounding binary triggers. Because they allow for a higher rate of fire, they can attract scrutiny. Always, *always* familiarize yourself with the laws in your local area, state, and at the federal level. Some jurisdictions may have specific regulations regarding the ownership or use of binary triggers. Ignorance of the law is not a defense, so research and ensure you are fully compliant.
Exploring the Features of the Fostech Binary Trigger
About the Company
Fostech Outdoors is a well-known name in the firearms industry, particularly for its innovative trigger systems. They’ve built a reputation for providing quality products designed to enhance the shooting experience. Their binary triggers have become particularly popular for their ease of use and performance.
Features and Construction
The Fostech Binary Trigger is typically constructed from high-quality materials, which can include hardened steel components, contributing to its durability and long-term reliability. This robust construction is crucial for withstanding the increased stress associated with rapid firing.
Selector Switch and Modes
The Fostech Binary Trigger design typically includes a dedicated selector switch. This switch is usually a three-position selector, providing safe, semi-auto, and binary firing modes. The presence of a dedicated safe position is, of course, paramount for safe handling of your weapon. The semi-auto mode allows the trigger to function as a conventional trigger, allowing for standard semi-automatic firing. The binary mode, of course, is where the trigger’s unique functionality comes into play. This gives you control of firing your rifle as a normal semi-automatic rifle, or a rapid firing binary firing rifle.
Ease of Installation
Many Fostech Binary Trigger models are designed as “drop-in” units. This means that installation is often straightforward, usually involving removing the existing trigger assembly and installing the Fostech unit. This can be done with basic tools and a little mechanical aptitude, a major plus for many gun owners.
Adjustability
Some models may feature adjustable trigger pull weights, allowing you to fine-tune the trigger’s feel to your preference. Some also offer adjustable overtravel, which can help minimize wasted trigger movement and further increase your rate of fire. These features can significantly enhance the overall shooting experience.
Compatibility
The compatibility of the Fostech Binary Trigger is usually quite extensive. They are typically designed to work with the AR-15 platform, which is one of the most widely used and modified rifles. They are generally compatible with standard mil-spec AR-15 lower receivers. Always double-check specific compatibility information for your firearm and any modifications you have made. Some Fostech triggers also come in a variety of different configurations depending on your need.
What Comes in the Box
The packaging of the Fostech Binary Trigger usually includes the trigger assembly itself, along with any necessary springs, pins, and often, a detailed instruction manual. Some models also include a set of adjustment tools if they feature adjustable components. Always make sure to check that all required components are included before you start your install.
Installation and Setup for the Fostech Binary Trigger
Safety First
The installation process for the Fostech Binary Trigger is designed to be user-friendly, particularly with the drop-in design. However, taking the time to carefully and correctly install the trigger is essential for safety and proper function.
Before you start, ensure your firearm is unloaded. Double and triple-check the chamber to guarantee the rifle is clear of any ammunition. Clear your workspace and gather the necessary tools: typically, a set of punches, a hammer, and possibly a small screwdriver, depending on your specific model.
Removing the Original Trigger
Installation generally involves removing the existing trigger assembly. This typically involves removing the hammer and trigger pins, then carefully removing the standard trigger, hammer, disconnector, and associated springs. Save these parts in case you wish to return your rifle to its original configuration.
Installing the Fostech Binary Trigger
The Fostech Binary Trigger then replaces the original assembly. The new trigger, hammer, and associated components are placed in the receiver, and the trigger and hammer pins are re-installed.
Reviewing the instruction manual, if provided by Fostech, is always the best practice. Pay close attention to the diagrams and recommendations. It is possible that an incorrect installation of the Fostech Binary Trigger can cause a catastrophic failure, rendering your weapon useless. If you aren’t comfortable performing the installation yourself, consider seeking professional assistance from a gunsmith.
Testing and Adjustments
Once the Fostech Binary Trigger is installed, inspect it to ensure it is properly seated and functions correctly. Test the selector switch to ensure the safe, semi-auto, and binary modes work as expected.
If your Fostech Binary Trigger has adjustable features, follow the manufacturer’s instructions for adjusting the trigger pull weight or overtravel. This fine-tuning can significantly improve the trigger’s performance and your overall shooting experience.
Performance and Testing: Putting the Fostech Binary Trigger to the Test
Testing Setup
To fully evaluate the Fostech Binary Trigger, range testing is critical. This involves shooting the trigger under controlled conditions to assess its performance and reliability.
The test setup should include a suitable firearm. The AR-15 platform is the most common, but the specifics of the firearm, such as barrel length, stock, and any modifications, should be noted. Ammunition is also a key factor. Testing the trigger with a variety of different brands, loads, and bullet weights is advisable to assess its performance with different types of ammunition.
The shooting conditions should be consistent for meaningful results. Outdoor ranges provide more realistic testing environment, and ensure the target distance and type are known to measure your accuracy and grouping. A stable shooting position, such as from a bench, can provide the most accurate assessments of the trigger’s performance.
Shooting Experience and Observations
During testing, focus on the feel of the trigger. How does the trigger pull feel in both semi-auto and binary modes? Is the pull smooth, or does it feel gritty or heavy? Pay attention to the trigger’s reset: is it crisp and positive? How does it affect your ability to shoot rapidly?
Assess the rate of fire in binary mode. How quickly can you discharge rounds? Is it as fast as you expect? Can you maintain control while shooting at a rapid pace? Record the rate of fire, and compare it to a standard trigger to get a clear understanding of the performance difference.
Accuracy
Accuracy is still a key consideration, even when focusing on speed. Evaluate how well the trigger allows you to maintain accuracy while shooting quickly. How do your groupings compare to those achieved with a standard trigger?
Reliability
Testing the trigger’s reliability is also essential. The more rounds you put through it, the better sense you’ll get of its longevity and the likelihood of malfunctions. Record the number of rounds fired and note any instances of failure to fire, failure to eject, or other malfunctions. Observe the trigger’s performance with different types of ammunition to see if it is more sensitive to certain loads.
