ALG Defense Combat Trigger (ACT)

Stock Status:

Out of stock

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.

    Great Single Stage Trigger.

    I have this trigger and also a BCM trigger. They are close as far as feel. One thing nice about this ALG trigger is that it comes with 2 springs one is like 4.5lbs and the other is 5.5-6lbs. Love this trigger! Great upgrade!

    Simply superb

    I love this trigger. No more scritchy scratchy long trigger pull. S,other clean break. Used the mil spec spring for the heavier SHTF reliability for combat but still smooth a glass and clean break. Nice. Also have the BCM trigger that came with a lower kit and it is very sweet aspot well.

    ALG combat trigger for 416

    Trigger showed up and is well made. I have ran about 500rds threw the gun rocking the ALG and it has functioned flawlessly. Overall a great and affordable trigger upgrade for anyone looking for a smoother trigger with the heavy mil spec style hammer... Thanks BCM

    ALG ACT Trigger

    Absolutely the best single stage trigger under $120. BCM order fulfillment and shipping process is the best in the business.
