Introduction To AR15 Trigger Upgrades

The AR15 is a highly customizable rifle that is widely used for both recreational shooting and tactical operations. One of the most common upgrades that firearm enthusiasts make to their AR15s is upgrading the trigger. A better trigger can improve accuracy, reduce recoil, and provide a smoother shooting experience. However, with so many options available on the market, it can be difficult to determine which type of trigger upgrade is right for you.

There are three primary types of AR15 trigger upgrades: single-stage triggers, two-stage triggers, and drop-in triggers. Each type has its own unique advantages and disadvantages, and choosing the right one depends on your individual needs as a shooter. In this article, we will explore the differences between these types of triggers and help you make an informed decision about which one to choose for your AR15.

What Is A Single-Stage Trigger?

A single-stage trigger is the most common type of trigger found in an AR-15 rifle. This trigger features a simple design with a consistent pull weight throughout the entire trigger pull. When the shooter pulls the trigger, it moves backward until it releases the hammer, which then strikes the firing pin and ignites the cartridge. The single-stage trigger provides a clean break without any creep or overtravel, making it ideal for target shooting and precision shooting applications.

These triggers are typically less expensive and easier to install than two-stage triggers or drop-in triggers. Single-stage triggers are also preferred by those who prefer a lighter pull weight as they can be adjusted to have a lighter pull than other types of triggers. However, they may not be suitable for some tactical applications that require more control over trigger pull weight.

What Is A Two-Stage Trigger?

A two-stage trigger is a type of trigger that has two distinct stages or phases. The first stage involves the initial take-up of slack or free play in the trigger, while the second stage involves the actual break or release of the firing pin. This type of trigger is often preferred by precision shooters and marksmen because it allows for more control and predictability in the trigger pull.

With a two-stage trigger, shooters can apply pressure to the first stage to prepare for the shot without actually firing, then smoothly transition to the second stage when ready to release the shot. This helps reduce movement and anticipation, leading to greater accuracy and consistency. Two-stage triggers are often adjustable, allowing shooters to customize their pull weight and travel distance according to their preferences and shooting style.

What Is A Drop-In Trigger?

A drop-in trigger is a type of trigger assembly that is designed to be easily installed into an AR-15 rifle without the need for gunsmithing or special tools. It typically includes a complete trigger group, including the trigger, hammer, disconnector, and springs, all housed in a single unit. This makes it an ideal option for those who want to upgrade their rifle’s trigger but don’t have the technical expertise to install a traditional trigger assembly.

Drop-in triggers are also known for their consistent and reliable performance, as they are engineered with precision components that ensure smooth operation and minimal creep. They come in both single-stage and two-stage configurations, allowing shooters to choose the type of trigger pull that best suits their shooting style and preferences. Overall, drop-in triggers offer an easy-to-install upgrade that can significantly improve the accuracy and performance of your AR-15 rifle.

Pros And Cons Of Single-Stage Triggers

Single-stage triggers are the most commonly used trigger type in AR-15 rifles. They have a simple design and function, making them reliable and easy to use. The main advantage of a single-stage trigger is its simplicity, which translates to a lighter pull weight and faster reset time. This makes it ideal for shooting situations that require quick reaction times, such as competitive shooting or hunting.

However, the simplicity of single-stage triggers also means they lack the precision of two-stage triggers. The lack of a distinct take-up stage can make it difficult to achieve consistent trigger control, especially in high-pressure situations. Additionally, single-stage triggers can be prone to accidental discharges if the shooter isn’t careful. Overall, if you’re looking for a reliable and straightforward trigger upgrade that won’t break the bank, a single-stage trigger is an excellent choice.

Pros And Cons Of Two-Stage Triggers

Two-stage triggers offer a different feel than single-stage triggers. They have two distinct stages: the first stage has a bit of take-up before it stops, and the second stage has a cleaner break. This can provide a shooter with better control over their shot placement. Additionally, two-stage triggers tend to have lighter pull weights than single-stage triggers, which can reduce fatigue during extended shooting sessions.

However, two-stage triggers may not be suitable for all types of shooting. They are more commonly used for precision shooting where consistent trigger pulls are necessary for accuracy. In situations where rapid fire is required, such as in tactical or defensive scenarios, the additional take-up can slow down the shooter’s ability to fire quickly and accurately. Additionally, two-stage triggers tend to be more expensive than single-stage options and may require some gunsmithing skills to install properly.

Pros And Cons Of Drop-In Triggers

Drop-in triggers have become increasingly popular among AR15 enthusiasts due to their ease of installation and improved performance. One of the main advantages of drop-in triggers is that they are pre-assembled, making installation quick and simple. This means that even novice gun owners can upgrade their trigger without needing special tools or professional assistance.

Another benefit of drop-in triggers is their consistency and reliability. Unlike other types of triggers, the components in a drop-in trigger are designed to work together seamlessly, resulting in smoother and more predictable trigger pull every time.

However, there are some downsides to drop-in triggers. They tend to be more expensive than traditional single-stage or two-stage triggers, which can be a deal-breaker for budget-conscious gun owners. Additionally, some purists argue that the simplicity of a drop-in trigger takes away from the customization aspect that makes AR15s so popular among gun enthusiasts.
