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...

Good Trigger

ALG ACT Trigger

by johnchip, Verified Owner from CT, United States Written on March 29, 2026
ALG does a very nice job at polishing the surfaces of this trigger to give it a nice crisp feel. I was in need of a quality but affordable single stage trigger for my 300 blackout home defense build and this fit the bill perfectly. Super easy to install and overall feels great to fire. Highly recommend it.

best trigger under $80

by TechOps, Verified Owner from NY, United States Written on January 4, 2026
If you’re looking to upgrade your Mil-Spec trigger Without spending $150-$200 look no further. You can’t beat this trigger for the price. Well done geissele.

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+
