JoeBob's AR15 Grip Screw Trigger Adjuster

THE best bang for your buck to improve any AR15 Trigger!  One of the BEST upgrades possible for a mil-spec fire control group, period! This trigger adjuster replaces the factory grip screw to reduce trigger creep, lessen pull weight, and improve hammer break for better accuracy. Use alone or as part of a complete trigger job.  Use this to fine-tune any mil-spec trigger or even the ALG ACT Nickel Boron Trigger!  These can be used in combination with the JP reduced power springs to take the pre-travel out of a trigger and reduce the trigger pull weight.
