Now shooters can replace their AR Trigger with one that is smooth and breaks crisp. The trigger is factory preset with a pull weight of 3 pounds. Installation is quick and no adjustments are necessary, 100% true drop-in trigger. The trigger module installs using your rifle's original hammer/trigger 0.154 pins and the proprietary design eliminates pin rotation and walkout.
