Dirty Bird Industries AR-15 Trigger Reduced Power Spring Set
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 4.0-4.5 lb trigger pull.
The DBI Reduced Power Spring Set have been designed to work with single-stage triggers and will not work with two-stage triggers.
Backed by the Dirty Bird Industries Lifetime Warranty
