The ALG Defense Advanced Combat Trigger (ACT) is designed for those shooters where tradition, value and regulatory concerns are of primary importance. The pull of the ACT is very similar to a standard mil-spec trigger, however it is sharper and the grittiness of the stock trigger pull has been removed while the traditional reliability of a stock trigger remains. The pull weight is not lower than the M4/M16 minimum weight specification of 5.5lbs.

Note about HardLubing:

HardLubing is ALG's term for electroless Nickel plating with 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.

Testing has shown that differential coating of the trigger parts contributes to the sharpness of the ACT's single stage pull. The trigger component is plated with Nickel-Boron which has a high surface hardness combined with excellent wear resistance. The color is a pleasing matte light grey that may be painted on non-functional surfaces if the shooter so desires (such as the trigger bow that is visible outside the lower receiver). The hammer, disconnector and trigger/hammer pins are plated with Nickel-Teflon which combines a low coefficient of friction with good wear resistance. The Teflon impregnation colors the metal a mottled, greyish/green. Parts coated with Nickel-Teflon cannot be painted. Both coatings are highly corrosion resistant eliminating the oil seal of traditional phosphated firearm components.

    Almost the same as the Geissele triggers for almost a quarter of the cost. No complaints.

    Great option

    Posted by Richard Morris on Jun 4th 2019

    This trigger comes ready to drop in and includes pins. Crisp break and wipes clean. A terrific option over standard mil spec.

    Easy install. Great feel. Haven’t fired yet and that’s the only reason for the four star

    Can’t say enough about how awesome this trigger is for the money. Barely any noticeable take up with a very crisp break.

    Better than Mil Spec

    Smoother, crisper, and lighter than Mil Spec for only a little more money.

    Comes with a trigger pin installer pin which makes it easy to install. Smooth with no grit like a standard trigger. It breaks clean. Real improvement.
