Description

If you've ever run a bone-stock AR trigger and thought it felt heavy, gritty, or just plain rough, the Hiperfire EDT 2-Stage is one of the easiest fixes for that. It's a two-stage fire control group built for AR-15 and AR-10 lowers, using Hiperfire's Radical Sear Mechanics to give you a smooth take-up, a positive wall at the second stage, and a clean break that resets with an audible, tactile click. This is the trigger that made two-stage feel accessible without stepping into premium-price territory, and it's a genuine step up over anything Mil-spec.

What Sets the EDT 2-Stage Apart

The clever part of this design is how it separates pull weight from hammer strike. The EDT ships with two color-coded hammer springs so you can tune the feel to your liking. The blue spring gives you a 3.5-pound first stage with a plus-1-pound second stage for a 4.5-pound total pull, while the green spring bumps that to a 4.5-pound first stage and a 5.5-pound total. Both springs are heavy-duty by design, which means the hammer hits hard enough to reliably light off harder primers and surplus ammo that lighter aftermarket triggers sometimes struggle with. That combination of a medium, controllable pull and a strong hammer strike is exactly why this trigger has a following among duty, service-rifle, and all-around builds.

Installing the Hiperfire Enhanced Duty Trigger

This is a component-style trigger rather than a fully sealed drop-in cassette, but Hiperfire includes an alignment pin and clear step-by-step instructions, plus install videos on their site. Most folks with basic tools and about fifteen minutes at the bench can knock it out without a gunsmith. It fits standard small-pin AR-15 and AR-10 lowers and works across common calibers like .223/5.56, .300 BLK, and 6.5/6.8 with US primers.

Bottom line, the EDT 2-Stage gives you a real, feelable improvement in trigger break, reset, and control, and the ability to swap springs means you can set it up the way you like and leave it there. It's a smart pick for anyone who wants better trigger feel without babying the reliability side.

Frequently Asked Questions

Is the Hiperfire EDT 2-Stage a true drop-in trigger?

It's a component-style fire control group rather than a fully self-contained cassette, so a few parts install into the lower individually. Hiperfire makes it painless by including an alignment pin along with detailed printed instructions and online install videos. Most people with basic bench tools can finish the job in about fifteen minutes without a gunsmith.

How do I set the pull weight on the EDT 2-Stage?

The trigger comes with two color-coded hammer springs so you pick the feel during install. The blue spring gives a 4.5-pound total pull, and the green spring gives a 5.5-pound total pull, each with a crisp plus-1-pound second stage. You choose one spring for your build, and you can always swap later if you want a different feel.

Will this Hiperfire trigger fit my AR-10?

Yes, the EDT 2-Stage is designed for both AR-15 and AR-10 platforms using standard small-pin lowers. It works across common calibers like .223/5.56, .300 BLK, and 6.5/6.8 running US primers. It isn't recommended for blowback or pistol-caliber carbines.

Does the heavy hammer spring help with reliability?

That's one of the standout points of the EDT design. The heavy-duty hammer springs deliver a hard hammer strike, which means more consistent ignition even with tougher military-surplus ammo and harder primers. You get a manageable medium pull weight without sacrificing that reliable primer strike.
