The ALG Defense Advanced Combat Trigger (ACT) is a premium upgrade for AR-15 rifles, designed for shooters seeking the trusted reliability of a mil-spec trigger with enhanced smoothness, sharpness, and corrosion resistance. Featuring a pull weight above 5.5 lbs to meet M4/M16 military specs, the ACT improves upon standard triggers with HardLubing—ALG's advanced electroless nickel plating process using Boron or Teflon to deliver superior wear resistance, low friction, and excellent corrosion protection. Ideal for law enforcement, duty use, or value-conscious builders, the ACT maintains stock geometry for consistent function while offering a refined single-stage trigger experience.

- Full-force hammer spring ensures reliable ignition with all ammo types
- Corrosion-resistant mil-spec springs

ALG Defense Combat Trigger

Nice trigger and easy to install. I also used the KNS non rotation pins instead of the stock pins. The trigger pull is #6 to #6.2 according to my scale.

ALG Act Trigger

Excellent value, much better then the OEM trigger. If factory triggers came like this...most would never bother to change them.
ALG ACT much better than stock
by anonymous
Great drop in replacement for stock trigger or new build. Picked it up on sale and glad I did! Noticeable improvement in trigger feel and it looks good.

AR 15 Builds

With a little bit of polishing and an enhanced spring kit I would put these up against triggers costing more than twice as much.
Noticable improvement
by Roy Dowell
While this is not a Geissele or Timmeny trigger for 1/3rd the cost it is a great value and a vast improvement over the standard AR15 trigger. Smooth with a crisp break, I have not measured the trigger weight but it seems lighter.
Great Trigger for the money
by TAHCO Gunworks, Tim Hasselbach
Well made, very smooth trigger feel. Put a set screw up the pistol grip hole to take up the slack, add a JP ambi safety, and you'll have a first class trigger that breaks like a glass rod. Also get some JP 3.5 or 4.0 lbs springs. I can do a trigger for a third of some of the high priced stuff, and my customers all say it's way better than the high priced products.
