AR-15 Trigger Reviews: Choosing the Right Custom Trigger Kit

Although the AR-15 is popular among civilians, it was a military weapon first and foremost. Its creator didn’t mean it to be a precision firearm. It was the semiautomatic version of the M-16. 

As such, it comes with a flaw that plagues most military-style weapons: the trigger. You can use it as it is, but you’re much better off upgrading it with an aftermarket trigger.

This is the opportunity to get one that best suits your needs. You’ll have to consider the different kinds of triggers to see which one you need. Then, keep on reading to see some AR-15 trigger reviews.

AR-15 Trigger Types

Before we go on to finding out the best AR-15 triggers, let’s take a quick look at the different types of triggers first. This will help you distinguish which from which, allowing you to choose the one that best suits you.

1. Mil-Spec Triggers

When people say mil-spec triggers, they mean the standard sort of triggers. Most AR-15s off-the-shelf come with mil-spec triggers.

The real definition of mil-spec is a far cry from standard, though. It’s an abbreviated form of “military specifications.” As such, it complies with the military unit or departmental standards.

2. Single-Stage Triggers

Single-stage triggers are the most common type; they have no slack during the take-up. The sear engages as soon as you pull the trigger. 

That’s because the full weight of the trigger is on the spring and sear. When a shooter fires their gun with a single-stage trigger, they only need to pull through that weight.

It offers speed, reliability, and crispness; its ease of operation and simple design are its major advantages over other types of triggers.

3. Two-Stage Triggers

Two-stage triggers differ in that it has a short and light initial take-up. You reach a brief stopping point before the firearm goes off. Note that this movement isn’t the same as the creep.

Many shooters use the initial take-up as prep time. They do it before they’re ready to shoot, so when the time comes, they only need to pull past the stopping point to shoot.

It’s great for precise and long-distance shooting. It offers more control, allowing you to be as precise as possible.

The second stage is light, however, so users are prone to premature shooting if they’re not careful. 

4. Drop-In Triggers

Drop-in triggers are ready to use out of the box, so no tinkering or such required. A “cassette” or housing already contains all the internal AR-15 parts, like the trigger shoe, sear, hammer, and so on. 

As they’re preassembled, you don’t have to worry about variances. Drop-in triggers are consistent in areas like the creep, trigger reset, and overtravel. 

You don’t need to have a special skill when converting to drop-in triggers.

5. Match Triggers

Light triggers are what we call match triggers because they’re most often used in matches and competitions, although they’re also used for long-distance shooting. 

This definition is a bit broad, though, and so shooters may have different ideas of what they consider to be competition triggers. 

In general, match triggers have lighter springs and smoother action. It also has faster firing pin strikes and a short reset.

Best AR-15 Trigger Reviews

With that out of the way, let’s move on to the best AR 15 trigger options in the market today. You decide which one is best for you by reading our AR-15 trigger reviews below.

1. ALG Defense Quality Mil-Spec (QMS) Trigger

This trigger is an enhanced mil-spec trigger, so it’s like your stock trigger but better. This is for those who want to stick with a stock setup for its reliability but an upgraded one.

The ALG Defense trigger has a coating of nickel boron. This, combined with polishing, makes for a smoother operation.

It also reduces the pull weight to 6.5 pounds, which is lighter than the standard mil-spec. Note, however, that there’s still some creep and pretravel as the polishing doesn’t do much in those areas.

2. Hiperfire Hipertouch Series 

If you want the lightest mil-spec trigger, however, look no further than the Hiperfire Hipertouch series. 

Its modified mil-spec design allowed for a low pull weight of 3.5 pounds. It improves the hammer strike, too.

It has less creep than the standard mil-spec trigger, although there’s still some overtravel. The reset is nice and crisp, but not that audible or tactile. 

Keep in mind, though, that Hiperfire’s mil-spec trigger has more extra parts. Installation isn’t as easy as you would expect. Still, the design only adds a couple of steps.

3. Rise Armament Super Sporting Trigger

This one is a drop-in trigger, so installation is pretty easy. You have to keep the standard springs out of the way, though, when you screw it in.

It’s a massive upgrade over your standard mil-spec trigger. It reduces the pull weight to 3.5 pounds.

It has a small initial take-up with almost no trigger creep and little post-travel. The reset is good; it’s audible and tactile. The follow-up trigger pulls are similar to the initial pull, as well.

To top it all off, it’s affordable, too – it’s priced only slightly higher than an enhanced mil-spec trigger.

This TriggerTech model allows you to adjust the pull weight of the trigger from 2.5 to five pounds. This enables you to use the same trigger for any shooting context, whether for long-distance or competitive shooting. You can adjust it while it’s in the receiver.

As expected of a Timney trigger group, it has a smooth and crisp operation. It has almost non-existent pre-travel with a clean break.

6. Timney Calvin Elite

The most adjustable trigger title, however, goes to the Timney Calvin Elite. It’s designed as the personal trigger of the company’s CEO, so you can ensure its quality.

Its trigger pull is at 1.5 pounds. While that’s great for competitions and precision shooting, it’s not the best choice for defensive or duty rifles.

You can adjust its trigger shoes to four different settings. You can also adjust the trigger length and length of pull, allowing you to create a perfect fit for your hands.

There’s zero pretravel or creep, but it has a little overtravel. It has a crisp break, though, and an audible and short reset.

Elftmann – or ELF – SE features sealed ball bearings, creating silky-smooth pulls. This drop-in trigger is the most affordable model from ELF for competitors.

There’s a tad bit of creep, although the break’s crispness is still unmatched. The reset is short, audible, and tactile. 

At 3.5 pounds of pull weight, this is an excellent competition-grade trigger. However, you can also use it if you want an extra nice trigger for your duty or defensive gun. 

7. Elftmann Three-Gun Trigger

For three-gun competitions, though, get the ELF trigger designed specifically for such. It’s a single-stage trigger that offers fast-action shooting.

It’s adjustable, too; you can adjust its pull weight from 2.75 to four pounds. This is a great enough range for competitive shooters.

As usual, the break is clean and crisp. There’s no pretravel or creep, and it has a short and audible reset. It’s not so tactile, however.
