The ALG Defense Advanced Combat Trigger, or ACT (brand part no. 05-199), is a factory-replacement-style AR trigger built for shooters who want a meaningful upgrade over a standard mil-spec trigger without straying from mil-spec pull weight requirements. ALG designed the ACT for shooters where tradition, value, and regulatory concerns matter, keeping the trigger’s feel close to a standard mil-spec unit while sharpening the break and removing the grittiness that stock triggers are known for. The pull weight stays at or above the M4/M16 minimum specification of 5.5 pounds, making the ACT a natural fit for duty, competition rule sets, or any build where a lighter aftermarket trigger isn’t appropriate. It’s a drop-in upgrade for shooters who want a cleaner trigger pull while keeping their rifle within traditional mil-spec parameters.
