ALG Triggers – Duty-Grade Simplicity, Better-Than-Mil-Spec Performance

If you’re tired of gritty, heavy mil-spec triggers—but don’t want to spend Geissele money—the ALG Defense Trigger is your answer. Designed by the sister company of Geissele Automatics, ALG’s ACT and QMS triggers bring you cleaner breaks, smoother pulls, and enhanced reliability, all without breaking the bank.

This is a true upgrade from standard AR-15 fire control groups—built to perform in real-world conditions, whether you're training hard, competing casually, or running a defensive setup.


🔧 Which One’s Right for You?

ACT – ALG Combat Trigger:
The ACT is treated with Nickel Teflon coating for an ultra-slick, corrosion-resistant finish. Expect a crisp pull with minimal creep—ideal for patrol rifles, training carbines, or any AR where reliability and clean function matter.

QMS – Quality Mil-Spec Trigger:
The QMS offers the same mechanical performance as the ACT but skips the coatings to stay budget-friendly. Still smooth. Still consistent. Still way better than that gritty factory mess.


💥 Why Upgrade to an ALG Trigger?

  • Improved feel – Smoother break and reset, with no mushy wall

  • Drop-in compatible – Fits standard AR-15 and M4 lowers

  • Duty-ready – Tested for harsh environments, not just benchrest bragging

  • Cost-effective – Get Geissele DNA without the Geissele price tag

  • Trusted by law enforcement and military trainers

  • Made in the USA – Quality machining, tight tolerances, no gimmicks

❓ Frequently Asked Questions

What’s the difference between the ALG ACT and QMS?
The ACT has slick, coated components (Nickel Teflon) for a smoother pull and better corrosion resistance. The QMS uses phosphate coatings and is more budget-focused—but still a solid upgrade over stock.

Are ALG triggers drop-in?
Yes. Both ACT and QMS are drop-in replacements for any mil-spec AR-15 or M4 lower. No fitting or mods required.

Are these triggers good for defensive or duty rifles?
Absolutely. The ALG ACT especially is a favorite among trainers, LEOs, and shooters who want a rugged, clean-breaking trigger without sacrificing reliability.

Will this improve my accuracy?
A cleaner trigger break and reset often results in better consistency and control—which can definitely help with follow-up shots and tight groupings.

Do these come with trigger pins and springs?
Yes. Both versions include complete trigger kits: hammer, trigger, springs, and pins.
