ALG Combat Trigger (ACT)

The ALG Defense ALG 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.

  • The ALG Defense ACT trigger pull is smoother and
    sharper than a stock trigger. This is accomplished by
    polishing the sear surfaces smooth and HardLubing the
    trigger components.
  • Sear geometry has not been changed from the
    standard profile so the high reliability that the stock trigger
    is known for is unchanged.
  • Trigger and hammer are made from true 8620 alloy
    steel military specification castings, correctly carburized,
    quenched and tempered for high surface hardness.
  • Disconnector is 1070 High Carbon steel properly
    Austempered into the spring range of hardness.
  • Springs are corrosion resistant and meet military
    specifications.
  •  A full force hammer spring is used for positive ignition
    of all type of ammunition.
  • Trigger and hammer pins are improved over stock mild
    steel by using 4140 Chrome-Moly steel that has been
    quenched and tempered. Pins are centerless ground to
    a fine finish and a diameter 0.001” larger than stock to
    reduce play in the trigger assembly while retaining a slip fit
    into the weapon lower receiver. Both pins are Nickel-Teflon
    coated.
  • Pull weight is above the U.S. Military minimum pull
    weight of 5.5lbs but does not reach near the upper limit of
    9.5lbs. Generally, the pull weight is about 6.0lbs.
  • As a trigger meeting the essential U.S. Military
    trigger specifications for the M4 Carbine, the ALG Defense
    ACT can be substituted for lower performing stock triggers
    while still staying in compliance with Unit or Departmental
    requirements.

    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.
