What To Consider While Buying The Best Triggers for AR 15?

When looking at competitions triggers for your AR 15, there are many different things to consider. Knowing these considerations will help you make an informed decision about what triggers you to buy.

Trigger Pull Weight

The first thing you will want to consider when purchasing a trigger for your AR 15 is the pull weight of the unit. The pull weight refers to how much force needs to be applied to the trigger to fire. Triggers range from 2 pounds up to about 9.5 pounds, with most quality units coming in at about 4.5 pounds.

Trigger Style

The next thing you will want to consider is the style of trigger that you plan on using. There are three main types of triggers for AR 15 rifles, and each one has its unique advantages and disadvantages. They include Single Stage, Two Stage, and Flat trigger or Curved trigger. A single-stage trigger is the most straightforward unit and only provides a single trigger pull mechanism. These units typically have a very light pull weight but lack much precision that you can achieve with other types of triggers for your AR-15.

A two-stage trigger features a smooth, light pull for the first part of the unit’s travel, and then it becomes much harder for the remainder of its travel. These are great original triggers that allow you to have greater control over your AR-15. A flat or curved trigger provides a different feel through its design. Many people prefer these units because they activate the same way, making them very predictable. They also have a light pull weight which is great for accuracy and precision shooting.

Safety Considerations

The most important thing to consider when purchasing a trigger is a manual safety mechanism built into it. Many triggers on the market do not have this type of safety, which means you will need to purchase an aftermarket unit from a trusted source if you want to use your AR-15 for tactical purposes, hunting, or competition shooting. As you can see, there are many options available for triggers for your AR-15 rifle, no matter what your needs are. Whether you want the essential trigger out there or something with advanced safety features to protect your investment, you will be able to find just what you are looking for by taking your time and doing some research before making your final choice.

Trigger Reset

The next thing to consider is the trigger reset. The reset is the point you need to go through before firing your next shot. Different triggers have different ways of accomplishing this, so be sure to read up on the different kinds of triggers and what makes them different from one another.

Aftermarket Vs. Mil-Spec Triggers

Another thing to consider is whether you want an aftermarket trigger or a mil-spec unit. An aftermarket trigger will typically have more features, but it will also be considerably more expensive than one that comes with the gun out of the box. On the other hand, a mil-spec trigger is usually the same as the one that comes with your weapon, so it will not have any special features to speak of.

Brand Name Vs. Economy Model

When buying a trigger for your AR 15, you also consider whether or not you want to buy a budget trigger or a brand name model. A good brand name trigger will usually cost between $100 and $150, while an economy model will generally sell for around half that much.


The final thing you need to consider before purchasing a trigger for your AR 15 is the features it has to offer. A good quality unit should have user-adjustable features, such as the pull weight, test weight, trigger reset, and pre-travel. A good economy model should have some of these features, but they may not be adjustable in the same way as a more expensive unit.


The price of a trigger for your AR 15 can vary greatly depending on the type that you choose. A good model will generally run you between $100 and $150, while an economy unit will sell for around half that.

There is no best trigger for an AR-15. You need to do some research and choose based on your needs and how much money you have to spend.

In most cases, you do not need to replace your trigger unless it is defective or if the gun stops working altogether. However, you may want to upgrade your unit to a better one if you have problems with accuracy.

The trigger group is the entire assembly, including the trigger mechanism and the hammer, sear, and disconnector. Replacing a defective part in this group will fix any problems that you are having with your AR 15.


The trigger is the only moving part on a firearm, so it makes sense that you will need to have a good one if you want your AR 15 rifle to function correctly. Whether you are looking for an economy model or a more expensive option with unique features, there is something out there for any budget and every need. As long as the trigger is not defective, it will usually last as long as your AR 15 rifle. However, if you start to notice specific problems with the gun’s accuracy or firing speed, then chances are that there is something wrong with the trigger, and you need to give it a replacement ASAP. Hopefully, this article about the best triggers For AR 15 helped, and good luck.
