Dirty Bird Industries is excited to announce their new Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set! Mil-Spec triggers have been used for decades, but have always suffered from an incredibly heavy trigger pull weight, that can be upwards of 7-8lbs. When installed, the Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set is capable of producing a consistent 4-5lb trigger pull depending on the fire control group being used and the finish of the engagement surfaces.
