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.
SPECS: Hammer/trigger – 8620 steel. Disconnnector – 1070 high-carbon steel. Hammer/trigger pins – heat treated 4140 chrome-moly steel. Both kits contain trigger, trigger spring, hammer, 2 hammer springs, disconnnector, disconnnector spring, hammer and trigger pins, and instructions.?
