Just to save anybody the trouble... I recently bought the fostech echo sport binary trigger.. (different from the ARII trigger) it’s not a drop in, and it’s an absolute ***** to do on your own. Directions are crap, the only video for install is recorded from across the table so you’ll never see him build that trigger inside the lower. If you’re like me and like to be your own gunsmith, feel free to reach out if you’re having any problems. 6785026320
