SOLD ATF approved Binary Trigger M4 **SOLD**

$130 OBO Includes shipping. <br><br>I have a Binary Trigger M4 that was approved by the ATF. I would upload the letter but I am not comfortable showing my real name anywhere. <br><br>You can get a binary trigger for the price of a standard trigger if you get a kit but I did not. This trigger came assembled in a factory drop-in but the manufacturer was one of the first to be approved. The kit that would make a binary trigger (frame, trigger spring, etc.) is still available for $60 but this is already assembled. <br><br>M4 Trigger: $250<br>Installed Kit: $60<br>My Binary: $130
