Most Helpful Positive Review Very Nice Trigger
I replaced my trigger with this one and couldn't be happier. For the money this is a great trigger. I had original built my lower with the CMMG lower kit. Usually I can work on those and get them where I am happy but not this one. I didn't want a hair trigger since this is a self defense gun. If ...

Most Helpful Negative Review Trigger Has Serious Flaw
Bought this trigger for a premium build. Installed it and performed several function tests including "hammer fall" test. Worked great and had a clean, crisp break with almost no take up. Took it to the range and about the ninth shot I experienced a double fire. This continued sporadically through ab...

ALG Combat Trigger for AR15

by Dogstar, Verified Owner from FL, United States Written on November 3, 2025
I bought a Haga Defense lower for my CZ Bren 2 . Normally I like Geissele single stage triggers but they recommend against them because of some dimensional issue . They recommended ALG as a viable option . When I saw they were a sister company to Geissele I thought it was a good choice . Single stage , nickel boron coated . Crisp break and short reset . Comes with 4 1/2 pound spring and 6 pound spring . Very good for a combat trigger . For the money , worth it but obviously not a Geissele . That’s the only reason I didn’t give it 5 stars . It’s a definite upgrade to what came stock on the Bren .

Awesome for the price

by Ohio dude, Verified Owner from OH, United States Written on October 3, 2025
It’s a no-brainer if you want a nice enhanced mill spec trigger that does not cost you an arm and leg. It comes with two different springs for trigger pull weigh and a slave pin to make it easy to install. Works every time!

Guaranteed to be a good milspec

by M, Verified Owner from UT, United States Written on March 31, 2025
lots of milspec triggers are heavy, have tons of slop, etc etc. This one is tight, light, and has a good reset. I've used them in a few different builds over the years. I've handled better triggers cheaper and more expensive than it, but I've also found inconsistency with the cheaper ones. ALG tends to have a really good consistency for making a good product, which means you don't really have to question whether or not it's gonna be good for a reasonable price. A+

ALG Defense ACT Trigger

by Paul H., Verified Owner from FL, United States Written on December 10, 2024
I love this trigger. It's the best trigger for the money, in my opinion, and I will definitely buy more for some of my upcoming builds. It's not too light or heavy, just right, considering it also has a break-in period. Anyone looking for a good, inexpensive trigger should try ALG Defense. You will not be disappointed.

Excellent trigger

by Fabio Rodriguez, Verified Owner from FL, United States Written on August 23, 2024
If you are looking for a single stage trigger, this is it. 4.5 lbs is light enough IMO, it's fast and crisp. No need for Geissele's expensive and extra light triggers.
Pros:
  • easy installation
  • Great quality & function
Cons:
  • None
Best Used for:
  • single stage trigger

Simply Amazing Performance to Cost

by steel, Verified Owner from GA, United States Written on August 19, 2024
After being gifted one of these triggers I absolutely fell in love with it, so much that I had to get another for a second build. I love the Nickel coatings for high corrosion resistance and slick finish. I love the positive reset, reliability, and simplicity of the enhanced mil-spec. I’m currently running the standard spring in one, and the lighter spring in a scoped setup. The standard spring is fast and positive without being excessively heavy. The lighter spring hasn’t had any problems yet and is a very nice change for longer range. The break feels great, nothing like the mil-spec feel, just a smooth clean snap. If you really try hard you can find a small bit of travel sometimes, but these parts want to slip apart with the appropriate pull weight and do so without any gritty feel. I highly recommend this trigger for anyone wanting a simple high quality upgrade without delving into the absurdly expensive and unreliable options.
Pros:
  • Quality
  • Affordable
  • reliable
  • Finish
Cons:
  • None
Best Used for:
  • everything

First time trigger purchase

by Nate, Verified Owner from NV, United States Written on August 15, 2024
My new ALG trigger surprised me with how crisp the release was and no more long pull to get there. This is my first aftermarket trigger and when I learned that ALG is owned by the wife of geiselle owner I knew the product would be top notch. Very happy with this purchase and I will soon add more to my other builds.
