ALG Defense Combat Trigger (ACT)

Stock Status:
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.

    ALG ACT trigger.

    Excellent trigger. Smooth consistent pull every time. It is easy to feel the trigger reset. If you are required or want to keep a mil spec trigger this is what you are looking for. I would suggest this to a friend. I will put one in every AR I own.

    ALG Defense Combat Trigger (ACT)

    This trigger went in fine and has a nice crisp feel to it. Glad I upgraded it. Price was right for me. This was the first upgrade to my AR-15

    ALG quality

    Trigger was easy to install and really jump in feel from my original Milspec trigger. Slight take up with no creep with the included purple spring felt like a 4.5-5 pound break. Not 100% crisp, but crisper than Milspec. Will be purchasing one for my 6.8 SPC II hunting AR.

    Nice trigger

    For being a sub $100 trigger couldn't be happier. Works great and has a crisp break.

    Great alternative trigger.

    ALG ACT trigger is an excellent upgrade if you prefer reliability of a mil-spec trigger with a much cleaner, lighter pull. Comes with two hammer springs to fine tune pull weight. Works flawlessly with all ammo including steel case with hard primers.
