Why Go With an AR-10?
The AR-10 is all about firepower. It is a semi-automatic rifle with a detachable magazine. It fires big centerfire rifle cartridges such as the 6.5 Creedmoor and .308 Winchester. These higher calibers have far more range and power than the AR-15’s midrange rounds.
Personally, I like the AR-10 for long shots or close-range hunting of dangerous species. Not only will you be able to hit targets at longer distances, but you will also be able to take down larger game animals. You’d be hard-pressed to find any large game in North America the AR-10 can’t deal with at a reasonable distance.
This versatility is one of the main selling points of the AR-10. Suitable both at close and long-range. For tactical and hunting as well as a fun day at the range.
Like the other ARs, one of the most appealing features of the AR-10 is how configurable it is. In fact, the AR platform as a whole has more spare parts and accessories floating around on the market than practically any other firearms platform in the world.
This makes finding that perfect trigger a reasonably easy task. But, why upgrade the trigger at all?

Why Upgrade Your AR-10 Trigger?
A better trigger is one of the most effective ways to make your weapon more accurate. When you use an improved trigger, you’ll notice a difference right away. It should have less grit and creep, as well as a quicker reset than the trigger that came with your mil-spec AR-10.
Superior AR-10 triggers have a lot faster and more precise reset. As such, it allows for faster and more accurate follow-up rounds. This is especially useful in a tactical situation. In other words, while the trigger on your mil-spec AR-10 should operate, you may improve it even more. You can install a better trigger with a cleaner break and a shorter reset. Your rifle should, at the absolute least, become considerably easier and more fun to shoot.

AR-10 Triggers vs. AR-15 Triggers
The biggest difference between an AR-10 and AR-15 trigger lies in the military primers. An AR-10 trigger will usually have a heavier hammer and hammer spring. Its primary use is to strike the primers of the larger .308 Winchester or 7.62x51mm rounds.
Moreover, triggers marked with AR-10/AR-15 are normally compatible with both platforms. Yet, triggers sold solely as AR-10 triggers or AR 308 triggers are likely only going to work in the AR-10 platform. And likewise, some lighter triggers meant for the AR-15 will not work with the AR-10.

Buyer’s Guide to the Best AR-10 Triggers
If this is your first time upgrading your AR trigger then you are in for some fun. I understand how intimidating it might be as well, but read on and we’ll tackle the ins and outs of finding and replacing the AR-10 trigger. There are a few factors to keep in mind.
Single vs Two-Stage Trigger
AR-10 triggers can be single-stage or two-stage. Single-stage triggers are the most common and simplest of the two. You operate it by giving one consistent smooth pull and at the end, it pops and the bullet goes off.
Double or two-stage triggers start off with the same smooth pull, but halfway through it gives you firm resistance before you pull through the second stage before you strike the bullet. This type of trigger is tactile, giving the shooter more control over the trigger pull.
You can take up the slack, then improve your aim before firing with the second stage’s lighter trigger pull. The second stage produces less motion since it requires less force. You’ll know exactly when to fire if you use a high-quality double trigger.Â
As I said, the single-stage is the most common and likely the one you already have on your AR-15. Their simplicity makes them long-lasting and easy to use.
Many prefer these, but if you want that split second to readjust and get a little bit extra control, then a two-stage trigger is the one for you.
Trigger Pull
Pulling weight, how much force you got to apply to the trigger, is a delicate balance. For most uses, a trigger should have a pull weight of between 2 to 5 pounds. However, this is an area where personal preference makes a big difference. The good news is that many triggers come with the adjustable draw weight. This is a feature it is worth paying extra for.
Trigger ShapeÂ
The shape of your trigger will also impact the accuracy and your enjoyment. Flat and curved triggers are the two most frequent trigger shapes. Flat triggers allow you to extend your pull reach. Curved triggers, on the other hand, have a smaller surface area and a shorter pull reach. There is no right or wrong choice, and it is entirely up to you to decide which one you like.
Installation
If you want to keep the installation simple, a drop-in trigger is ideal. There is no need for the help of a gunsmith or any specialist tools to install a drop-in trigger. The disconnector, hammer, and trigger are all kept together in one case. All you have to do is swap out the trigger and you’ll be good to go.
How to Install an AR-10 Trigger
Below are the 10 steps to installing an AR-10 trigger:
- Begin by gathering the following materials: Belt Sander, Military Push Pins, Firing Pin, Allen Screws, Plastic Mallet, Solvent, Padded Clamp, Compressed Air, Loctite.
- Push out the takedown pins from your AR and remove the upper assembly of the AR-10 from the lower assembly.
- Set the lower assembly in a padded clamp. Set the upper assembly aside.
- Degrease the lower assembly using compressed air and the solvent.
- Remove the old trigger group and Insert the new trigger well into the lower receiver.
- Insert the trigger pins and gently tap them in using the rubber mallet.
- Install an Allen screw in each side of the trigger cartridge, so the trigger cartridge is pushed up.
- Install one Allen screw over each of the Allen screws from the last step. This prevents the first screws from falling out.
- Place the lower receiver and the upper receiver back together.
- Test the trigger to make sure it works.
