How does a Binary Trigger work? ♻️
📢 As we mentioned above: a binary trigger is a type of firearm trigger that allows the shooter to fire two rounds with a single pull of the trigger.
- 🔹 When the trigger is pulled, the first round is fired as it would be with a standard trigger.
- 🔹 When the trigger is released, its special mechanism activates and causes the trigger to reset, allowing another round to be fired when the trigger is pulled again.
⚙️ Binary triggers use a special mechanism that essentially “fires” the weapon on both the pull and the release of the trigger:
- 📍 This is achieved through a sear mechanism that holds the hammer in place until the trigger is pulled. When the trigger is released, the sear releases the hammer and allows it to move forward, striking the firing pin and firing the second round.
⚠️ It’s important to note that these triggers can significantly increase the rate of fire of a firearm and may be restricted or prohibited in some jurisdictions.

What are the Types of Binary Triggers? 💁🏽♂️
🔎 After a thorough examination, our team came to the conclusion that there are generally two types of binary triggers:
- 💡 Mechanical
➔ These triggers use a purely mechanical design to release the hammer or striker for the second shot. They work by using the recoil from the first shot to reset the trigger, which then releases the hammer or striker again for the second shot.
- 💡 Electronic
➔ These triggers use an electronic mechanism to release the hammer or striker for the second shot. They work by using a microprocessor to detect the movement of the firearm’s bolt carrier group, which then sends a signal to release the hammer or striker for the second shot.
📢 Both types allow for a rapid rate of fire and are popular among gun enthusiasts.
When it comes to finding the best binary trigger for you, there are many factors to consider. From selecting a compatible platform and understanding your needs as a shooter to considering safety features, customization options, and value for money; all of these aspects must be taken into account before making an informed decision. We hope that this comprehensive guide has provided useful information about different types of triggers available on the market today so that you can make an educated choice when buying one for yourself. With careful consideration and research, we’re sure you’ll find the perfect option for your shooting requirements! 😉
The Fostech Echo trigger system, which I had purchased in the past, did not meet my expectations when it came to its performance in semi-automatic mode. The trigger pull was heavy and felt like it was pulling against a rubber band. Although the binary mode functioned, it was not practical for serious usage. I have since repurposed it as a range toy, installed on an Aero Pew lower, and I plan on getting a 22LR upper for it to use as a fun, low-cost shooting option.
I had a Franklin Armory Binary Firing System (BFS) installed on my CZ Scorpion. While it was a fun range toy, it was nothing more than that. The BFS often failed to fire the second shot and it turns out that one of the springs was too weak, but it could be replaced easily. This is a known issue with the CZ platform. Due to the upcoming election, the possibility of new regulations regarding short barrel rifles (SBRs) and the high cost of ammunition, we decided to sell it at a gun show. Additionally, the BFS would quickly burn through a 50-round drum, which my wife had asked me to avoid doing. Ultimately, I found that I couldn’t resist the temptation to shoot the entire drum.
As binary triggers have become increasingly popular in the firearms community, we wanted to create a thread to address some of the common questions and misconceptions surrounding these trigger systems.
Below, you’ll find a list of some frequently asked questions about binary triggers. If you have a question that isn’t answered here, feel free to ask and we’ll do our best to provide an answer.
Q: What is a binary trigger in simple words?
A: A binary trigger is a trigger system that allows the shooter to fire a round with each pull and release of the trigger. In other words, when the trigger is pulled, the gun fires, and when the trigger is released, the gun fires again. This is known as the “binary” mode.
Q: Is a binary trigger legal?
A: The legality of binary triggers can vary depending on the location and jurisdiction. In some states, binary triggers are completely legal, while in others they may be restricted or outright banned. It’s important to check your local laws and regulations before purchasing or using a binary trigger.
Q: How does a binary trigger differ from a bump stock?
A: A binary trigger and a bump stock both increase the rate of fire for a semi-automatic firearm, but they work in different ways. A bump stock uses the recoil of the gun to “bump” the trigger back into the shooter’s finger, causing the gun to fire again. A binary trigger, on the other hand, fires the gun both on the pull and release of the trigger.
Q: Is a binary trigger safe to use?
A: As with any firearm, the safe use of a binary trigger depends on the user’s knowledge, experience, and adherence to firearms safety guidelines. It’s important to fully understand the operation and function of the binary trigger before using it and to always follow the manufacturer’s instructions.

I recently installed a Franklin BFSIII C1 trigger into my Springfield Saint Victor AR15 rifle, which is mostly in its original configuration and has a 16-inch barrel chambered in 5.56. I was pleased to find that I didn’t need to swap out the buffer spring for either of the two included springs, although it was nice to have the option since they had different weights. At the range, the rifle performed exceptionally well in Binary mode, flawlessly firing all 30 rounds from a Full PMAG loaded with green tips. I was so impressed with the trigger that I plan to purchase more for any future builds.
I’m planning to upgrade my rifle with several new components, including a muzzle brake, a TiN or NiB Bolt Carrier Group, and a new trigger. However, I’m unsure whether to choose a Franklin binary or a gristle trigger. I’m interested in hearing your thoughts on the reliability of binary triggers and whether they’re more of a gimmick or have practical applications. My initial impression was that they could help me fire more rounds accurately and quickly at a target.
I would suggest opting for a light binary trigger such as the Franklin trigger or a similar option and then honing your skills with double-taps through practice.
I’ve installed the Franklin trigger on my PTR C93 and have been thoroughly impressed with its performance, particularly when paired with Tula steel ammo. While I initially encountered issues with steel and brass ammunition when using the 9mm version, I was able to remedy the problem by switching to the heavier hammer spring. Since making that adjustment, I haven’t experienced any issues with the trigger’s functionality.
In my experience, I’ve owned multiple binary triggers, but the only ones that have functioned consistently for me are the MP5 version from Franklin Armory and the AR Echo trigger from Fostech.
Upon receiving my trigger, I opted to have a professional gunsmith handle the installation. I picked up the rifle two days later, and the gunsmith had already test-fired three magazines without encountering any problems whatsoever. If you haven’t tried a binary trigger, I highly recommend giving it a shot.
Are binary triggers safe to use?
✅ When installed and used correctly, binary triggers can be safe. However, they require additional training and practice to use effectively and safely. The two-shot burst can be difficult to control and may increase the risk of accidental discharges. ⚠️ It’s also important to note that binary triggers may not be suitable for all types of firearms, and installing them may void the manufacturer’s warranty.
📢 Furthermore, some jurisdictions have specific regulations on the use of binary triggers, and it is important to understand these laws before installing or using one.
The binary trigger is a blast for some range fun! I’m definitely thinking about buying more of ’em. It’s super easy to add to any AR lower, and I’ve got a couple on my range gun. When I used it with some mixed 300blk ammo, it just made me grin ear-to-ear. But a word to the wise: make sure you’re using a full buffer tube, ’cause I got a little surprised when it went off!
I’ve put a few hundred rounds through the Fostech Echo trigger without encountering any problems at all. It’s hands down the best upgrade you can make to your AR. The trigger is user-friendly and the installation is a breeze. The only drawback is the price, but believe me when I say it’s worth every penny.
What should I look for when purchasing a binary trigger?
📢 When purchasing a binary trigger, here are some factors to consider:
🔵 Compatibility: Make sure the binary trigger is compatible with your firearm. Not all binary triggers will work with all firearms.
🔵 Quality: Look for a binary trigger that is well-made and has a good reputation for reliability. A poorly made binary trigger can be dangerous and can cause malfunctions.
🔵 Safety: Ensure that the binary trigger has safety mechanisms in place to prevent accidental discharges. These safety features may include a trigger block or a safety selector switch.
🔵 Price: Binary triggers can be expensive, so consider your budget when making a purchase. However, do not compromise on quality and safety for a lower price.
🔵 Legal considerations: Be aware of the laws in your area regarding the use of binary triggers. Some states and municipalities may have restrictions or bans on these devices.
🔔 Additionally, always follow proper firearm safety practices and receive proper training before using any firearm.
I purchased a binary trigger about a year ago and it’s been a favorite of mine ever since. I’m even planning on incorporating it into future builds. I did make one change by swapping out the springs to reduce the trigger pull weight, but other than that, I haven’t experienced any issues with it.
