AR-platform rifles are fun and versatile, but the standard, mil-spec triggers leave much to be desired. They tend to be gritty, with creep and heavy pull weight. One of the easiest, most effective AR upgrades is a trigger group swap. An improved fire control group makes a huge difference. There are many aftermarket trigger options for the AR platform rifles. Choose single-stage or two-stage, either standard trigger assembly or unitized “drop-in” trigger, such as those made by Timney or Triggertech.

Two-Stage vs. Single-Stage Triggers
Two-stage triggers have two separate movements. The first stage offers a light, spring-loaded pressure that works against the shooter’s pull until stopping at the second stage – this is called “take-up”. If there is no spring pressure, it is known as “slack”. Should the shooter continue to pull the trigger once he’s arrived at the second stage, the mechanism will operate like a single-stage trigger from there until engaging the sear and firing the gun. Some shooters prefer a two-stage trigger because it allows a mental preparation (first stage) before the final decision to “break the shot”.

Single-stage triggers feature no take-up or slack, as they begin engaging the sear as soon as the shooter begins pulling the trigger. Some competitive shooters prefer the two-stage trigger because of the feedback it provides during its first stage, while other shooters, including those using their rifle in tactical scenarios, may want the surety of a single-stage trigger, ready to engage and fire once their finger is inside the trigger guard. Regardless of preference, a good trigger will feature minimal creep and should be free of grittiness, providing a smooth, even break.

Drop-In Trigger Assembly vs. Standard Trigger Group
Once you decide between a single-stage or two-stage trigger, you can choose between standard and drop-in trigger groups. Standard trigger groups feature all the fire control group parts separated, and need to be pieced together and installed much like a mil-spec trigger, while drop-in trigger are pre-assembled and contained within a casing that simply drops in to the receiver and accepts the pins, hence the name.

After-Market Trigger Comparison

Some shooters prefer drop-in triggers due to the ease of installation, while others opt for standard groups so they can access the components individually for cleaning adjustment or replacement. If one piece of a drop-in trigger fails, you’ll need to either replace the entire unit or send it to the manufacturer for repair, whereas you may be able to simply replace the broken component of a standard trigger without needing a whole new trigger set.

Trigger Terminology — “Creep”, “Stacking”, “Overtravel”
“Creep” or “travel” is the distance the trigger moves between the end of take-up and when the trigger breaks to fire the fun. Too much creep can affect accuracy, but no creep can be unsafe, as the shooter may not be prepared to fire. “Stacking” occurs when the trigger weight actually increases during travel — this shouldn’t happen. Lastly, “overtravel” is the distance the trigger continues moving back after the gun fires.

The fireworks are over, and folks are returning to their jobs, but many Fourth of July Sales are still running through the weekend. We found some great deals at Palmetto State Armory (PSA). If you’re a black rifle fan, or a pistol shooter, you should definitely check out these deals. Many high-quality products are deeply discounted, including Vortex Optics, Geissele triggers, and Smith & Wesson pistols. You’ll also find great deals on AR components — stripped lowers, complete lowers, and complete uppers.

Here are a few deals we found on the PSA website. There are hundreds of other items on sale. The super-low prices for PSA’s 4th of July Sale are good through 11:59 PM EST on Monday, July 8, 2019. If you see a deal that appeals, grab it before the prices go back up Tuesday morning.

In this video, Bill Geissele explains how to install a Geissele SSA Trigger:

Are you thinking of upgrading the trigger system for your AR-platform rifle? There are dozens of options available, from $45 up to $300. Thankfully, Brownells has created video reviews of some of the more popular AR trigger options from Timney, Geissele, and ALG Defense. And we included a video review of the highly-regarded Elftmann Match Trigger. If you want the best solution for Service Rifle competition, you might favor the Geisselle. For ease of installation, it’s hard to beat the Timney, a “drop-in” module. Like the Timney, the super-smooth Elftman is a drop-in module. At $249.00 it’s pricey, but it is one of the best AR triggers out there. If you’re on a tight budget, the best “bang for your buck” may be the “Perfected Mil-Spec” ALG which starts at around $45.00.

Geissele Enhanced Two-Stage Trigger

Geissele makes a variety of quality AR trigger sets both single-stage and two-stage. Many High Power competitors like the two-stage Geissele trigger. This delivers a repeatable, controlled pull through the first stage with a very clean break in the second stage. The Super Dynamic Enhanced Trigger, shown above, features a distinctive, trigger blade. Reviewer Thomas Conroy says: “The flat surface is very easy to press against. Both stages are light and very distinct.”

Elftmann Drop-In Match Trigger

Though pricey ($249.00 at PrimaryArms.com), we really like the Elftmann AR trigger. It combines the best of both worlds — the precision and smoothness of the Geissele with the Timney’s ease of installation. This single stage trigger is user-adjustable from 2.75 to 4 pounds pull weight. It is offered with either straight or curved trigger blade. Primary Arms says: “The amazingly short take-up, glass-rod crisp break and [near-zero] over-travel can be compared to the finest custom 1911 triggers.”

Timney Drop-In Trigger Module

This trigger module is available for both the AR15 and the AR10 platform (as covered in the above video). Timney triggers are easy to install and come with multiple pin size and pull-weight options. Reviewer Thomas Conroy confirms that the single-stage Timney “breaks cleanly and crisply. This trigger is modular, meaning that the trigger, sear, hammer, and spring are all encased in a bright, shiny yellow aluminum housing.”

ALG Defense Trigger — Higher-Quality Basic AR Trigger

According to Thomas Conroy, ALG triggers “are the perfected version of the standard, non-adjustable mil-spec original trigger. They have the same geometry, but are made to higher quality standards, and come with … hardened and smoothed-out sear contact surface to eliminate all grittiness.” These are also offered in a nickle-boron coated version. Available for under $45.00, the ALG is a well-made, low-cost option for shooters who want a better factory-type trigger system.

Geissele Automatics manufactures a line of two-stage triggers favored by top Service Rifle, High Power, and 3-Gun shooters. Geissele now offers a variety of trigger models for both large-pin and small-pin lowers, with pull weights from 1.8 lbs to 6.0 lbs. You select the Geissele trigger with the appropriate first and second stage pull for your discipline (refer to chart below for trigger model specs).

Video Shows Geiselle Trigger Installation in AR15
Our friend Gavin Gear of UltimateReloader.com has crafted a video showing how to install a Geissele National Match Trigger in an AR15. This video covers installation of the trigger assembly, the trigger guard, the safety selector lever assembly, and the pistol grip.

Follow-Up Video for AR10 Trigger Install
Gavin recently released a follow-up video which covers the installation of a Geissele Super Dynamic Trigger in an AR10. The procedure is mostly the same as for the AR15, but this video also covers removal of the AR10 factory trigger, so it’s worth watching. You may want to turn the volume down on your computer’s speakers before playback. CLICK HERE for Geissele Trigger Instruction Manual
