Why Upgrade to a Binary Trigger System?

A binary trigger system is a game-changer for any serious shooter. Unlike a standard semi-automatic trigger that fires one round upon the pull, a binary system fires a second round upon the release, essentially doubling your rate of fire without violating federal law.

Key Advantages:

1. Increased Rate of Fire: Achieve the fastest practical semi-automatic firing speed—perfect for competitive shooting or just a fun day at the range.
2. Enhanced Control: The ability to cancel the release shot (a feature on both the Fostech Echo and Franklin Armory BFSIII) provides a critical safety mechanism and tactical control unmatched by other high-speed systems.
3. Legal Compliance: A binary trigger is not a machine gun under federal ATF definitions, as only one round is fired per function (pull or release) of the trigger. This makes them a fully legal alternative to achieving near-full-auto speeds where local laws permit.

Our Top Selection of AR-15 Binary Triggers

We pride ourselves on stocking only the best drop-in binary triggers on the market. Our inventory includes the most popular and high-demand models, ensuring you find the perfect AR-15 trigger upgrade to suit your needs and budget.

The Franklin Armory BFSIII

The Franklin Armory BFSIII (Binary Firing System III) is arguably the most recognizable and fastest binary trigger available. Known for its distinct three-position selector (Safe, Semi, and Binary), the BFSIII offers a crisp pull and an immediate second shot on the release. Shooters who value the absolute fastest trigger cadence often choose the BFSIII.

The Fostech Echo Trigger

The Fostech Echo AR-15 is another industry titan, famous for its innovative design that prioritizes reliability and safety with its proprietary Echo trigger technology. The Echo’s unique locking system is designed to prevent “hammer follow,” which is a common concern with high-speed triggers. It also features a true “Safe, Semi, and Echo” mode with a positive reset, ensuring you maintain precise control over your firing sequence.

Fostech Echo vs Franklin Armory BFSIII: Choosing Your Trigger

Choosing between the Fostech Echo Sport and the Franklin Armory BFSIII is often the biggest decision for our customers. While both offer a “pull and release” functionality, their mechanisms and feel are slightly different.

Understanding Binary Trigger Legality: What You Need to Know

A common question we receive is, “Are binary triggers legal?”

Federal Law: Binary triggers are classified as semi-automatic firing systems. The ATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives) has historically ruled that since a binary trigger only fires one shot per function of the trigger (one on pull, one on release), it does not meet the definition of a “machine gun” under the National Firearms Act (NFA) or Gun Control Act (GCA). This means that binary triggers are federally legal to purchase and own in most states.

We ship to all legally permissible states in the US and Canada. It is, however, the sole responsibility of the purchaser to understand and comply with all applicable federal, state, and local laws before ordering and installing any binary trigger kit.

Installation Guide: Your Drop-In Binary Trigger

Most of the binary triggers we sell, including the Franklin Armory BFSIII and Fostech Echo, are designed as drop-in trigger units for the AR-15 platform. While professional installation is always recommended, many experienced gun owners choose to perform the upgrade themselves.

A Step-by-Step Overview (Always follow the manufacturer’s instructions):

1. Safety First: Ensure the firearm is unloaded and clear.
2. Disassembly: Remove the upper receiver and existing fire-control group (trigger, hammer, disconnector, springs).
3. Installation: Insert the new binary trigger kit assembly, securing it with the provided trigger and hammer pins.
4. Selector: Install the new, necessary three-position safety selector (Safe, Semi, Binary/Echo).
5. Function Check: Perform a thorough function check as detailed in the manufacturer’s manual (crucial for safety and legal compliance).

The Future of Semi-Automatic Firepower is Binary

A binary trigger is not just a modification; it’s an evolution in semi-automatic rifle performance. By providing a truly unique and exhilarating shooting experience, these triggers have become one of the most popular AR-15 accessories on the market.
