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.” The above video shows the installation process start to finish. There is also a “mil-spec” version for $162.00 at Primary Arms.
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 $50.00, the ALG is a well-made, low-cost option for shooters who want a better factory-type trigger system.
