Are you thinking of upgrading the trigger system for your AR-platform rifle? There are dozens of options available, from $45 up to $350. 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 Geissele. For ease of installation, it’s hard to beat the Timney, a “drop-in” module. Like the Timney, the super-smooth Elftmann is a drop-in module. At $249.99 from Brownells 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 trigger at $49.00.
Multiple AR Triggers, including Elftmann and Geissele, Reviewed
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.”
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.”
Timney Drop-In Trigger Module
This trigger module is available for both the AR15 and the AR10 platform (see 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 nickel-boron coated version. Available for under $56.00, the ALG is a well-made, low-cost option for shooters who want a better factory-type trigger system.

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.
When upgraded with a precision trigger and match barrel, AR-platform rigs work great in NRA High Power competitions (Photo from NRA Blog, at Camp Perry).
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.

Want to upgrade your AR’s trigger? Shooting USA and Brownells have created a video tutorial that shows how to remove a factory AR trigger and replace it with an upgrade. This video illustrates the procedures to follow and the tools you’ll need. Step-by-step, the video explains how to swap the factory trigger group for a self-contained ‘box style’ drop-in trigger module or a traditional (multi-part) trigger system with enhanced performance.
Many AR-15s come from the factory with a military-type trigger that has a long, gritty, heavy pull. Replacing that trigger is one of the best ways to improve your AR’s performance. You’ll be rewarded with a smoother pull, shorter take-up, and reduced pull weight. You will also have a choice between a single-stage and a dual-stage trigger.
The box-style, self-contained drop-in systems from companies like AR Gold, CMC, Timney, and Wilson Combat are the easiest to install. John Scoutten explains: “These self-contained systems … are very simple to install. In fact, all you do is remove the factory parts, drop in the whole system, replace your pins, and you’re done.” Conventional two-piece trigger groups are offered by DPMS, Geissele, JP Enterprises, and Rock River.
The key points of the video tutorial are also explained on the Shooting USA website with text and still pictures. Before you start your trigger project, review Shooting USA’s AR Trigger Upgrade Page. You’ll find helpful close-up photos on that page.

M-K IIA2 GEN2 Tactical Trigger from The Wisconsin Trigger Co.
Gear Review by Johnny Fisher
Do you shoot an AR-platform rifle? Here’s an excellent trigger upgrade option that has recently returned to the marketplace. The Wisconsin Trigger Company (WITC) has resumed production of the legendary Milazzo-Krieger M-K II trigger for the AR-platform rifles. Not merely marketing a replica of the original Milazzo-Krieger design, Wisconsin Trigger now offers an enhanced, drop-in version called the M-K IIA2. An easy install, the Milazzo-Krieger trigger drops in with no special tools or machining required (and no modification of the safety selector switch).
For those who are looking for an extremely crisp AR15 trigger that closely mirrors the “feel” of a finely tuned M1 / M14 trigger, this trigger might be the solution. The first stage is exceptionally clean and smooth due to a proprietary diamond-grinding process. I felt that the first stage travel was longer than a Geissele, but many guys will prefer that. Upon reaching the very noticeable and defined “wall” of the second stage, a further increase of pressure provides the instantaneous snap one looks for in a high-quality trigger — complete with a total absence of anything resembling creep or slop.
If you follow the instructions in the box and watch WITC’s informative how-to videos, installation of this trigger is extremely straightforward, requiring no special tools or fitting.
As supplied straight from the factory, the first stage requires about 2.25 pounds of take-up before encountering “the wall” of the second stage. For this purpose of this review and to ensure “making weight” in CMP Service Rifle Competitions, the (white) 5-lb. disconnector spring was used. The weight of the second stage came in right at an extremely repeatable 5 lb. 3 oz. (averaging +/- 1.5 oz.) for a ratio of about 40/60 between the two.
Upon release of the hammer, the disconnector reset is decidedly short. National Match shooters in particular will appreciate the very short but easy-to-recognize trigger reset during rapid-fire strings.
Tuning the Trigger Before Installation
As with most National Match-grade triggers on the market, the Millazo-Krieger utilizes proprietary pins that come supplied with this unit. They must be used for final installation and are purposely oversized to a specific diameter for a very snug fit. This is to ensure the trigger and hammer rotate solely on the pins, as opposed to the pins eventually rotating inside the receiver. It is best to use standard sized mil-spec trigger and hammer pins for the setting of tensions (trigger weight) before final installation to help avoid undue wear to the receiver pin holes. Final adjustment of second-stage pull weight must be done BEFORE final installation.
It is recommended to first set the amount of desired disconnector engagement by performing a very simple process that is detailed in the included installation instructions from the TOP of the trigger. The swapping out of disconnector springs and final tuning of the second stage can then be done, but only from UNDERNEATH a disassembled trigger.
The disconnector tensioning springs are easily swapped out by removing the spring plug from the bottom of the trigger housing that exposes the spring pocket. After inserting the desired weight spring, the spring plug must be installed at least flush with the bottom of the trigger housing. Installing it deeper will add trigger pull weight on the second stage. Installing it too shallow will interfere with trigger movement.
Transferable Warrnty:
The Wisconsin Trigger Company offers a full lifetime warranty to all unaltered parts of its triggers. This lifetime warranty is fully transferable when the trigger is sold to a new user! When have you heard of an AR component manufacturer with a transferable warranty — we’re impressed.
