FosTecH Echo Sport Binary Trigger for the AR-15 Platform

Builders and Shooters know that the best upgrade you can do to your AR-15 is getting a reliable, smooth & light pull trigger. Thanks to the modularity of the AR-15 platform, upgrading your standard Mil-Spec Trigger with enhanced parts, or even a self contained all in one Drop-In trigger is as easy as punching out 2 pins from your lower receiver and ‘Dropping In’ your new upgrade. Binary triggers serve a special function of being able to increase the shooter's ability to shoot faster under a single action of the trigger. Binary triggers work by releasing the hammer when the trigger is pulled, and when the trigger is released. Binary Triggers are a great upgrade for standard AR-15 Rifles, and Pistol Caliber Carbines!

About this Trigger: The Fostech Echo Sport Trigger is more efficient, less complex, and most importantly LESS MONEY than other binary triggers. From an operational standpoint, the only difference the operator will notice is that the selector for the Echo operation is located inside the trigger well on a paddle. Move to the left for Echo Mode and move to the right for Semi-Automatic. The ECHO Sport is an economical pull and releases a trigger for the AR-15 platform. To explain how this trigger functions, every time you pull the trigger a bullet fires, and your BCG cycles a new round, when you release the trigger another bullet fires and your BCG then cycles another new round. This is not a machine gun, this is a single action for every round trigger which is the definition of semi-auto fire. One round per action on the trigger, once per pull, and once per release.

Compatibility: This trigger is designed to work with Mil-Spec AR-15 lower receivers and can be installed in just a few minutes!

Anti-Walk Pins: Not Included - This enhanced trigger is to be a direct replacement for your original trigger. Trigger pins are not included, but you can re-use the trigger pins from your standard lower parts kit.

Color: This trigger is Burnt Bronze accented.

Trigger Style: Standard M4 - This trigger uses a standard Mil-Spec curved trigger shoe.

Main Feature: Binary
