Fostech AR-15 Drop In Echo AR-II Binary Trigger


A binary trigger that isn't impossible to install!

Take your AR-15 to a new level with the Fostech AR-15 Drop In Echo AR-II Binary Trigger. This innovative trigger system brings a new level of versatility to your firearm, featuring safe, semi-automatic, and binary firing modes, all ATF-compliant. Compatible with Mil-Spec Ar-15 lower and parts, this binary trigger kit is a phenomenal upgrade for your AR-15 - no matter if you're on the range for fun, competing in a match, or just want a dependable and high-quality trigger.

ATF Compliant Modes:
Navigate between safe, semi-automatic, and binary firing modes seamlessly. The Fostech AR-II Binary Trigger ensures compliance with ATF regulations, allowing you to enjoy the benefits of binary firing while adhering to legal standards.

Binary Mode:
The third 'Echo' mode (Binary mode) allows for a shot to be fired on both the trigger pull and release, providing a rapid and controlled shooting experience. This unique capability offers enhanced versatility, making it an excellent choice for both tactical and recreational shooting scenarios. If you're concerned about issues with firing a second shot when unwanted in binary mode, don't worry - the Echo Trigger is designed with safety being the utmost priority. When the shooter is in Echo Mode and depresses the trigger one round is fired, if the target moves, the shooter can move the selector to the safe position and a second round will not fire upon release.

Compatibility with Mil-Spec AR-15 Lowers (Without Sear Block):
Designed to be compatible with AR-15 lowers, the Fostech AR-II Binary Trigger adds a dynamic element to your firearm. However, to ensure optimal performance, your AR-15 must have a full-auto M16 cut bolt carrier and a mil-spec lower without a sear block. This trigger is also a drop-in trigger and makes assembly simple and straightforward. Anti-walk pins are not required but are strongly recommended to ensure an easier installation and reliable function.

Manufactured in the USA Quality:
Trust in the quality craftsmanship of Fostech, with the AR-II Binary Trigger proudly manufactured in the USA. Fostech is renowned for producing reliable and high-performance firearm accessories, and the AR-II Binary Trigger is no exception.

Elevate Your Shooting Experience:
Whether you're a seasoned shooter or looking to upgrade the trigger in your AR-15, the Fostech AR-15 Drop In Echo AR-II Binary Trigger is an incredible choice. With its ATF compliant design and safe, semi, and binary modes, this trigger is well worth the price. Upgrade your AR-15 today and experience greater performance on the range.
