Overview

The ALG Defense Advanced Combat Trigger (ACT) represents one of the best value propositions in AR-15 triggers, designed by Bill Geissele himself to deliver premium trigger performance at an accessible price point. This trigger bridges the gap between basic mil-spec triggers and expensive drop-in units, offering a clean, smooth pull that rivals triggers costing two to three times as much.

The ACT achieves its superior performance through precision manufacturing and material selection. The trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched, and tempered for high surface hardness and durability. The disconnector uses 1070 high carbon steel properly Austempered into the spring range of hardness. All components receive HardLubing treatment - electroless Nickel plating with integrated Boron or Teflon to enhance surface hardness, wear resistance, and create favorable tribological properties.

The result is a trigger that maintains the proven reliability of mil-spec designs while delivering a noticeably cleaner break and stronger reset. The pull weight averages 6.0 lbs, meeting M4 carbine US Military specifications while eliminating the grittiness associated with standard triggers. For shooters who want enhanced trigger performance without breaking the bank, the ACT delivers exceptional value.
