From the manufacturer
Gives A Smoother Pull While Preserving Reliability
Trigger/hammer kits feature rugged military-type components carefully prepped to give a smoother trigger pull while maintaining the original geometry for maximum reliability. These are “enhanced standard” triggers, so the armorer continues to work with the configuration he’s accustomed to. The QMS (Quality Mil-Spec) set has the sear contact surface precision-honed to smooth and lighten the pull to around 6½ lbs. The ACT (ALG Combat Trigger) adds nickel-boron coating on the trigger and nickel-Teflon coating on the hammer, disconnnector, and pins to increase surface hardness and reduce friction, with an average pull weight of about 6 lbs.
