Product description

Upgrade your AR 15 trigger without spending a fortune – the ALG Advanced Combat Trigger features Hard Lubed components and polished sear surfaces.

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.This is accomplished by polishing the sear surfaces smooth and hard-lubing the trigger components.

Performance Advantages for the Shooter

  • 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.Geissele
  • 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.

Advantages for the Armorer

  • The ALG Defense ACT trigger is an enhanced standard trigger so maintenance and installation procedures are unchanged.
  • Trigger assembly parts may be interchanged between triggers, there are no matched sets.
  • 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 on Hard Lubing:

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.

Although many swear by a 2-stage trigger, I will forever be a single-stage trigger guy! As a result, I have utilized every technique available to refine the standard Mil Spec single stage trigger, including smoothing with stones, polishing, and changing springs! My last resort would be dropping them into a ceramic polisher!
Fortunately though, I decided to try out the ALG Defense ACT 6lb single-stage trigger. Wow, I could not be happier with this trigger… And it is worth noting that it was not simply the addition of lighter trigger/hammer springs that are responsible for it’s performance, it is instead the precision machining and the NB coating that make this trigger super nice!
I hear people talk about how horrible Mil Spec triggers can be, but as an ex-Marine, I do not recall ever having one (a bad SS)! This trigger allows me to go back to, “sight alignment, sight picture, squeeze!” Thanks ALG

I hadn't fired my Bushmaster XM-15 for quite a while and forgot how bad the stock trigger was. Over the past two years I acquired a PSA AR-15 and an AR-10, both of which have noticeably good triggers. About 3 weeks ago I fired the Bushmaster and was taken aback by how gritty the trigger was. Shortly afterwards I ordered an ALG replacement unit. About 3 days after I placed the order it arrived. I had never removed anything from an AR lower so I was a bit apprehensive but after watching a good YouTube video I tore into it. The kit comes with a slave which I thought was a simple and excellent thing to include. The new trigger parts went in easily. I used the 4.5# spring. I noticed a huge difference on the first test pull. Crisp and no grit. I can't wait to take it back to the range.

very nice fire control group! Smooth and crisp and very fast. I put the 6# spring in it because I may be shooting a variety of ammo. Easy install. Dramatic improvement
