ALG Defense

ALG Defense is a relatively new company started by Amy Geissele. They take unfinished 8620 alloy castings of standard issue M4 triggers as used by Colt and give them the Geissele magic. In addition to new pins and springs, they finish the triggers. They don’t change the overall geometry of the trigger but rather polish the sear surfaces smooth and HardLube the trigger components. HardLubing is how ALG refers to their electroless Nickel plating. They use an integral modifier to the base nickel plate. Either Boron or Teflon is used to enhance surface hardness, wear resistance and corrosion resistance and also create favorable tribological properties of the trigger components.

Currently, ALG Defense offers two models. The ALG Combat Trigger (ACT) seen below and the Quality Mil-Spec (QMS) Trigger.

Pull weight is above the US Military minimum pull weight of 5.5 lbs but does not reach near the upper limit of 9.5 lbs. Generally the pull is around 6 lbs. Installation is as a standard trigger and parts may be interchanged between triggers as there are no matched sets. In fact, your trigger is going to look like a standard trigger but under the hood, it’s a Geissele.
