Binary triggers are a great innovation in the firearms industry. The idea is to combine the safety of a double-action trigger with the speed of a single-action trigger. This allows you to be able to fire your weapon quickly when needed but also have it on safe when not shooting.
There are two ways that you can get this feature: either buy an aftermarket trigger or buy a gun that already has one built into it. Both options have their pros and cons, but overall I think the latter option is better because it’s easier and cheaper to install than buying an aftermarket trigger.
While there are several good binary triggers available on the market, it’s important to remember that what triggers you like best may not be right for everyone. The best trigger for you is the one that fires without fail, every time you pull its trigger. While these suggestions should help get you started on your journey, there is always room for improvement.
The Best Binary Triggers
FosTech AR-II Trigger
FosTechTrigger is a drop-in trigger upgrade for AR rifles. The AR-II is a two-stage trigger that gives your AR rifle a smooth, crisp, and light trigger pull. This will give you more accuracy and faster target acquisition. The FosTech AR-II Trigger has been designed and manufactured to last under the most demanding conditions. This trigger comes with a lifetime warranty against manufacturing defects from the manufacturer.
The AR-II has an adjustable pre-travel (length of pull) adjustment screw that allows you to tune the trigger to your preference. The pre-travel adjustment screw can be accessed through the bottom of the trigger housing without disassembling the gun, making it easy to make changes on the fly!
This trigger also has a 4 ½ pound first-stage pull weight with a 1-pound second-stage break weight which is adjustable by changing out springs in the trigger pack. This makes shooters looking for a light first stage and crisp break without having to change out springs in the gun itself during competition matches! The AR-II Trigger fits into any standard Mil-Spec lower receiver with no modifications necessary!
BFSIII AR-C1 Franklin Armory Trigger
The Franklin Armory BFSIII AR-C1 Trigger is the latest and greatest in the world of drop-in triggers. The BFSIII has been redesigned with enhanced features to provide the end user with a better shooting experience.
The BFSIII is a single-stage trigger that has been completely re-tooled to create a more durable, smoother, better-feeling trigger. The BFSIII has a pull weight of just 2.5 pounds and provides an extremely short reset which allows for faster follow-up shots and reduces input time between shots for higher accuracy.
The trigger body is CNC machined from 7075 T6 aluminum and hard anodized black for durability. The housing is made from 6061 T6 aluminum with a dry film lubricant coating for improved wear resistance. The hammer is made from 4340 steel, heat treated and cryogenically treated for maximum strength, hardness, and corrosion resistance.
The BFSIII AR-C1 Trigger comes standard with three different trigger shoe options: flat face (no finger grooves), semi-curved face with minimal finger grooves, or fully curved face with deep finger grooves for those who want to feel every bit of their trigger pull work into their finger pads before pulling back on it completely.
The BFSIII is perfect for 3 gunners or competitors looking for a reliable trigger with minimal take up, short reset, and no creep. This trigger is easily installed with no modifications needed to the lower receiver. The BFSIII also works perfectly in any other AR platform rifle including 9mm carbines!
BFSIII 22-C1 Franklin Armory Trigger
Franklin Armory’s BFSIII is a drop-in replacement for the factory sear to increase safety and improve accuracy in your AR-15 rifle. This is the first trigger system on the market that provides a user-adjustable sear engagement surface and trigger pull weight. The unique design of the Franklin Armory BFSIII allows you to adjust both pre-travel and over-travel while providing a crisp, clean break that is similar in feel to a 1911 pistol.
The BFSIII 22-C1 has been tested by top 3-Gun shooters and is used in competition by many high-profile competitors including Troy Landry who won 3rd place at his first match using it! It also features an over-travel stop screw for those who want their trigger to have an even shorter reset. With 4 different settings for pre-travel and over-travel, this trigger can be adjusted for any shooter regardless of skill level or desired pull weight.

This trigger has been designed to provide outstanding reliability and performance under harsh conditions.

The CZ-S1 is also compatible with our AR15 PCC Chassis System as well as our new.308 PCC Chassis System!
BFSIII PC-C1 Franklin Armory Trigger
The BFSIII PC-C1 is a high-performance, single-stage trigger that is an ideal upgrade for your AR-15. It’s made in the USA and comes with a lifetime warranty.
This trigger has a 4.5lb to 5lb total weight with about an 8oz break weight. The break is very crisp with no overtravel or creep. It also has a short reset which makes it great for precision shooting or competition shooting. This trigger will work on any mil-spec AR15 lower receiver but will not work with the Sig MPX due to its proprietary design.
The BFSIII PC-C1 comes in black color and weighs 9 ounces without any springs or pins installed. You will need to install the hammer spring, hammer pin, and trigger pin before installing this product on your gun.
The Hammer, Trigger, Disconnector, and Pins are all Nickel Boron coated to reduce friction and increase durability. The safety selector of the rifle has a crisp trigger break with an audible reset. The roller on the trigger provides smooth operation without the grittiness of traditional 2-stage triggers. Compatible with mil-spec forged lowers & uppers, but may not be compatible with billet receivers due to recesses in the fire control pocket or other features that impede installation.
Binary Trigger vs Bump Stock
Bump Stocks and Binary Triggers are both devices that allow semi-automatic firearms to fire at the rate of fully automatic weapons, but they work in different ways. While bump stocks are a mechanical add-on to the trigger mechanism of a rifle, binary triggers use electronics to simulate full auto fire.
Bump Stock: The bump stock attaches to the lower receiver (the part of the rifle that houses its internal components) of an AR-15 rifle. When the shooter pulls back on the trigger, it causes the gun’s rearward motion to be transferred into forwarding motion in the stock. The stock then slides forward while simultaneously pushing against a spring. This action allows a second round in the chamber to be fired before returning to its original position.
Binary Trigger: A binary trigger is an electronic device attached to an AR-15 rifle that allows it to fire multiple rounds one after another without any type of physical movement by the shooter. It works by using capacitors and transistors to electrically charge each round in succession as quickly as possible and then release them all at once through a single trigger pull from the user’s finger or thumb.
Binary triggers are something that many newbies and even some of those in the know may not immediately think to look for when purchasing an AR. Due to this lack of understanding, many overlook an excellent opportunity to extract greater accuracy. After doing additional research and testing on the subject, it became clear that binary triggers are a feature worth looking for.
So, if you’ve read through this list and now have an itch for something new and unique, go out and pick up one of these add-ons for your gun. Or maybe you’re looking to buy your first gun and want to find something that feels like home. No matter what the reason, our top mentions will do the trick!
