10 Best AR-15 Triggers: Drop-In and Mil-Spec

The barrel is the heart of a rifle, but a good trigger can greatly affect the performance and shootability of an AR-15. The difference between a factory trigger and great, modern trigger is night and day, and swapping them can take less than 10 minutes. There is a lot to consider when buying a new trigger. From pull weight and design to trigger angle and stage type, the modern AR-15 trigger has a lot going on, so it’s important to get all the facts and take your time when looking for the option that best fits you.

I like a nice trigger on a rifle (and handgun).

I've got several brands of "nice" triggers in AR15s. Rock River Arms. Geissele (couple different models). Rise Armaments (couple different models). The CMC triggers are nice, too. One or two other brands of drop in/cartridge style triggers.

The Rock River Arms was my first and I though it was awesome. The Rise Armaments triggers are nice, too. I didn't believe it till I shot it but the Geissele triggers were the best of all of them that I'm bought/shot. Enough better I could tell it with my finger but not enough better to make one rifle shoot better than another one if the other one also had a nice trigger.

I've had AR15 triggers that would make my trigger finger sore after a shooting session. Pull the trigger back, hold it at the wall, squeeze if to the rear that last little bit and repeat for a few magazines and darned if the tip of my finger hasn't gotten tender/sore from the effort required to hold it and move it that last little bit to fire the rifle. Those triggers get changed out as soon as I can get the aftermarket trigger shipped to the house. Shooting is supposed to be fun, right?

Timney, Hyperfire and AR Gold are the best triggers I’ve used on the higher end.

Larue MBT is probably the best bang for buck out there. It definitely feels like a more expensive trigger.

Rise are quite nice as well and have models all over the price range. I wore out an RA140 a couple years back, and they replaced it with a new one, no questions asked.

My POF 415 Edge came with a very nice four pound trigger; which actually feels much lighter than that. It’s hands down the best AR trigger that I’ve ever felt; much less owned.

10 Best AR-15 Triggers: Drop-In and Mil-Spec
Just a PSA.

The fact is that Mil-Spec has a very precise meaning.

According to a Government Accounting Office (GAO) report, “In general, ‘military specifications’ describe the physical and / or operational characteristics of a product and ‘military standards’ detail the processes and materials to be used to make the product.”

Mil-Spec, then, is related to Mil-Std, which stands for “military standard.” Together they comprise the specifications and standards for making a given product that the U.S. Department of Defense (DoD) has issued as a major part of DoD’s Standardization Program, the goal of which is to ensure that products designed for military use meet the necessary requirements with regard to quality, durability, ruggedness, commonality, inter- changeability, total cost of ownership, logistics and other military and defense-related objectives.

In the case of an M16 rifle or carbine, the military specification might require a weapon’s bolt ( or trigger group) to be made out of a certain type and grade of steel and for it to be made via a specific manufacturing protocol, while the military standard might outline the specific inspection and testing protocols for and relating to that part.

“Commercial black rifles or aftermarket parts are not considered Mil-Spec because there is no U.S. government verification to assure that their performance, endurance, accuracy, interchangeability and reliability meet all of the detailed and exacting military standards and specifications imposed by the United States Armed Forces.”

Just so we’re crystal-clear on this important point: no commercial AR-15 carbine or rifle, components are not nor ever will be, Mil-Spec. If the government is not testing the gun, by definition, it is not Mil-Spec. “Mil-Spec commercial” is an oxymoron.

Don't be sucked in by marketing hype.

I installed a Rock River 2 Stage trigger on a 20" AR I built. It is sweet, clean break average 2.5lbs, on the 2nd stage, Great for the range and coyote hunting. Great article OP!

My first AR aftermarket trigger was the Krieger-Milazzo and I went distinguished in a year ('95). Since then, I have installed many Rock River 2-stage NM and 3" Varmint triggers. For their price, they are a great 2-stage trigger. They hold a bit more weight on the 2nd stage than a Geissele and that is my reference. Have installed most premium triggers on the market the past 10yrs (American Gold, TriggerTech, etc) but have had great luck with the 3# Rave 140. It's what I use in my personal carbine. Great for rapid-fire and precision fire. Low creep, clean break and short over-travel.
