One of the biggest benefits of an AR-10 is the .308 round, which gives you more range and power. Your trigger is one of the most important parts of your rifle, when it comes to achieving maximum precision.
The right trigger will help you take advantage of the larger round and longer range of your AR-10.
Now, an AR-15 trigger will fit in your AR-10. However, .308 rounds often use military primers which are harder than 5.56mm primers. So, using a trigger that’s designed for an AR-15 may cause reliability issues for your AR-10.
Fortunately, almost all trigger manufacturers have AR-10 triggers that are identical to their AR-15 counterparts, but with stronger hammer springs to ensure your rifle functions reliably.
In fact, many manufacturers simply use stronger hammer springs on their AR-15 triggers, and you get the same unit whether you get one that’s labeled for an AR-15 or an AR-10.

Time to pull the trigger on this one.
1. Geissele Automatics AR-15/M16 Two-Stage - Best Overall AR-10 Trigger
Geissele is one of the companies that makes their AR-15 triggers strong enough to run in an AR-10. So, don’t be worried about the name. The Geissele Automatics AR-15/M16 Two-Stage Trigger offers an excellent combination of trigger feel and pull weight for a long range battle rifle.
The trigger feel comes down to the component construction and coatings. This trigger is made from tool steel, which is extremely hard and durable. Additionally, all the friction surfaces are coated to smooth out the trigger movement. All this helps you press your trigger without disturbing your point of aim.
Two-stage triggers are also excellent for long range shooting. A two-stage trigger breaks the trigger pull weight into two, lighter stages. This makes it easier to break your shots without shifting your rifle.
However, the total pull weight of this trigger is still about 4.5 pounds.
This is heavy enough that this trigger is suitable for fast, tactical shooting. But, it’s light enough and the two-stage design makes it an excellent long range trigger, as well.
Also, this trigger offers the reliability of a mil-spec design. Drop-in triggers have become plenty reliable. But, many shooters still find mil-spec triggers to be more trustworthy.
This trigger is suitable for a fully automatic rifle. However, Geissele also makes this trigger specifically for semi-automatic rifles. The Geissele Automatics AR-15/M16 SSA Trigger is the same two-stage trigger, but designed for tactical semi-automatic rifles.
If you’re not a hardcore single-stage trigger fan, this is an excellent trigger that’s an excellent option for long range, optic-assisted shooting.
2. ALG Defense AR-15 Enhanced Military-Style - Budget AR-10 Trigger
Just because a trigger is inexpensive doesn’t mean that it’s not good. The ALG Defense AR-15 Enhanced Military-Style Trigger is an excellent trigger that’s super affordable.
This is essentially a mil-spec trigger with better components. The contact surfaces have been precision honed to smooth out the trigger pull and reduce the overall pull weight. This is nice because it has the same feel and function as a mil-spec trigger, just better. If you’re used to mil-spec triggers, this trigger will be a direct upgrade for you.
The pull weight is set at 6.5 pounds. This is about a pound and a half lighter than a bone stock mil-spec trigger. This pull weight is excellent for tactical shooting. However, many will find it to be a bit too heavy for long range precision.
But, the mil-spec design delivers maximum reliability and compatibility. It may not deliver the most impressive performance. But, it will fit and function properly in almost any AR-10.
Even with the slightly heavier pull weight, this is an excellent trigger that provides maximum reliability, with an improved trigger pull, that comes at an outstanding price.
3. JP Enterprises AR-15/.308 AR Adjustable - Adjustable AR-10 Trigger System
If you’re building a custom AR-10, an adjustable trigger is almost a must. Is it even custom if you can’t, you know, customize it? The JP Enterprises AR-15/.308 AR Adjustable Trigger System makes your custom rifle truly customizable, the way a custom rifle should be.
The obvious selling point here is the adjustable pull weight. But, the overtravel is also adjustable. The pull weight can be set as low as 3 pounds. This is excellent for long range precision shooting. And, you can set the pull weight at 4 pounds if you want your trigger to feel more like a duty trigger.
The adjustment may not be an acceptable range for some professional applications. So, this trigger may not be in compliance with some military or law enforcement requirements.
Even though this trigger is adjustable, it’s still a mil-spec design, which ensures solid function and reliability.
So, you get adjustability without compromising your rifle’s reliability.
But, this trigger smooths out much of the grittiness that plagues mil-spec triggers. The tolerances are tight and the surfaces have been honed smooth. Which makes the trigger press much cleaner than a bone stock mil-spec trigger.
Even though this trigger doesn’t offer the precision adjustment of some bolt-action triggers, it still enables you to adjust your AR-10 trigger pull weight for a really reasonable price.
4. CMC Triggers AR-15 - Drop-In Two-Stage Trigger
The CMC Triggers AR-15 Two Stage Trigger is an easy-to-install upgrade over a standard mil-spec trigger.
This trigger gives you a much smoother trigger press than a standard mil-spec trigger. Threaded sleeves and oversized center pins ensure that the trigger movement is ultra-smooth, and prevent trigger wobble.
And, it’s a two-stage trigger which breaks the total pull weight into two stages. So, it’s easier to break your shots without moving your rifle.
The pull weight is not adjustable. But, the take up and overtravel are set very low from the factory. So, this trigger is suitable for tactical and long range shooting, right out of the box.
Drop-in triggers are easier to install than mil-spec triggers. Some shooters feel that drop-in triggers are less reliable than mil-spec triggers. However, this trigger has shown no signs of the reliability issues that gave drop-in triggers a bad name long ago.
And, even though it may not be pretty, the trigger housing is steel sheeting, which provides excellent durability.
It may not be adjustable, and it’s not the most affordable trigger ever. But, this is an excellent drop-in trigger option for those who want a direct upgrade for their stock trigger.
5. Timney .308 AR Drop-In Module Solid Shoe - Drop-In Single-Stage Trigger
Timney makes some of the best AR triggers on the market. The Timney .308 AR Drop-In Trigger Module Solid Shoe is the .308 model of the Timney AR-15 drop-in single-stage trigger. It’s incredibly easy to install, and the trigger press is excellent.
This trigger uses a heavier hammer to ensure reliable function in .308 rifles. Otherwise, it’s the same as the 5.56mm model.
Reliability is expected. Where this trigger really shines is in the trigger press.
The trigger press has almost zero uptake and creep. And, the break is exceptionally crisp. It feels a lot like a good bolt-action trigger.
The pull weight is set at 4 pounds, which is a good compromise between a duty trigger pull weight and a precision trigger press. So, this might be the best drop-in single-stage trigger for an AR-10 battle rifle that you use for both tactical and long range engagements.
And, all the trigger components are machined from tool steel for exceptional hardness and durability. The housing is aluminum, which keeps the weight low, without compromising the longevity.
This trigger is also on the high end of the price spectrum. But, it’s an excellent all-purpose trigger that will make your AR-10 a breeze to shoot in any context.
6. Geissele Automatics AR-15 Super Dynamic - Flat-Face Mil-Spec AR-10 Trigger
While a good curved trigger is an excellent option, a flat-face trigger offers better trigger finger placement and trigger feel for many shooters. The Geissele Automatics AR-15 Super Dynamic Trigger is an excellent option for those who want a flat-face trigger with an incredible pull.
The flat face is the main point of this trigger. A flat-trigger reduces the perceived pull weight, which gives you better control over your trigger press. It also gives better tactile feedback which helps you feel the reset for faster shooting.
The total pull weight is set at 4.5 pounds, which is separated into two-stages for more precise shooting. So, this is an excellent trigger for a designated marksman rifle or precision AR-10. However, the pull weight is high enough for duty and tactical use as well.
If you’re a competition shooter or use your AR-10 exclusively at long ranges, you may prefer the 3.5 pound or the single-stage 3.5 pound model.
But, these lighter triggers may not be suitable for a duty or tactical rifle.
As with all Geissele triggers, all the components are coated and honed for exceptional smoothness. This removes any grit or crunch in the trigger press, for a super smooth pull.
One of the nice things is that Geissele has made an exceptional mil-spec trigger. You get an excellent trigger, with mil-spec reliability.Overall, the price point of this trigger makes it best for high-end rifles. If you’re doing any serious long range or competition shooting with your AR-10, this might be the best trigger for you.
Getting Good Hits
A good trigger can be even more valuable in an AR-10 than it is in an AR-15 (though, your AR-15 trigger is still really important). The .308 round is capable of reaching longer ranges. So, a good trigger really helps you squeeze all that performance out of the larger round.
And, you can use your AR-10 trigger in your AR-15, if you enjoy swapping parts.
Geissele Automatics AR-15/M16 Two-Stage Trigger
If you want a trigger that will work for almost any AR-10 rifle and won’t force you to file bankruptcy, get the Geissele Automatics AR-15/M16 Two-Stage Trigger. It’s an affordable trigger that gives you a great trigger press.
