The ALG Defense Advanced Combat Trigger (ACT) is an enhanced Mil-Spec type single-stage trigger for AR-15 and AR-10, designed for shooters where tradition, value and regulatory concerns are of primary importance. It is very similar to Mil-Spec units in pull weight, but polished surfaces and hard-lubing provide a smoother pull with a sharper break. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5 lbs. Includes two hammer springs: Purple hammer spring: approx. 4.5 lb pull weight; Tan hammer spring: included for approx. 6.0 lb pull weight.
