FosTech Echo AR ll Binary Trigger upgrade with Militia State Armory Echo ll Tuning kit.

Awesome drop in trigger upgrade for your AR-15 to improve a smooth trigger pull and rate of fire. This ambidextrous version features a 3 position switch to swap between safe, single and giggle switch that can be changed on either side of the gun. The binary function allows you to fire one round on the trigger pull and then another when the trigger is released; making for an exceptionally high rate of fire. Super easy installation as you simply drop the trigger in and secure it with the two pins. Also includes a tuning bushing and spring upgrade for that extra smooth pull. Has had maybe 200 rounds put through it. Completely disassembled and cleaned to sell. Text is best. I can’t have my phone at work so leave a message or call again after 6 PM if I don’t answer.
