This is one of the Smoothest, Most Reliable Single stage trigger groups you will ever find..
For a lighter, even crisper trigger pull, (Approx 4.5lb) use JP Reduced Power Springs
& JoeBob's Trigger Adjuster
*Reduced power springs may cause light primer strikes if using hard mil spec/surplus 5.56 primers, or 5.45/7.62 surplus ammo. Trigger adjuster
will work on ALL mil-spec fire control groups including the Spike's Battle Trigger, with or without reduced power springs.
