Why settle for a sloppy trigger which can cause a good rifle to shoot badly? Now shooters can replace creepy two-stage triggers with one that is smooth and breaks crisp. The trigger is factory preset with a pull weight of either 3 or 4 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 pins and the proprietary design eliminates pin rotation and walkout.
