What is a 2 Stage AR Trigger?
When it comes to the world of firearms, the trigger is one of the most crucial components. It’s the part that connects the shooter’s finger to the gun’s firing mechanism. Among the various types of triggers available, the 2-stage AR trigger stands out for its unique design and performance. In this article, we will delve into what a 2-stage AR trigger is, how it works, and its advantages over other trigger types.
Understanding the Basics of a 2-Stage AR Trigger
A 2-stage AR trigger is a type of trigger found on many modern semi-automatic rifles, particularly those chambered in .223 Remington or 5.56x45mm NATO. Unlike a single-stage trigger, which has a consistent pull weight throughout the entire trigger stroke, a 2-stage trigger has two distinct stages. The first stage is lighter and serves as the take-up, while the second stage is heavier and requires more effort to break the shot.
Let’s take a closer look at the two stages of a 2-stage AR trigger:
| Stage | Description | Pull Weight |
|---|---|---|
| First Stage | Take-up stage, where the trigger is pulled smoothly without any resistance. | Varies, typically around 1-2 pounds |
| Second Stage | Break stage, where the trigger reaches its maximum weight and the shot is fired. | Varies, typically around 4-6 pounds |
How Does a 2-Stage AR Trigger Work?
The 2-stage AR trigger works by utilizing a series of mechanical components, including the trigger, sear, hammer, and firing pin. When you pull the trigger, the first stage is engaged, and the trigger moves smoothly without any resistance. This allows the shooter to focus on aiming and preparing for the shot.
Once the trigger reaches the second stage, the sear engages the hammer, which in turn strikes the firing pin. This action releases the pressure on the primer, causing the gun to fire. The distinct stages of the trigger make it easier for shooters to identify when the shot is about to be fired, which can be beneficial in competitive shooting or when precision is crucial.
Advantages of a 2-Stage AR Trigger
There are several advantages to using a 2-stage AR trigger:
- Improved Accuracy: The distinct stages of the trigger make it easier for shooters to identify when the shot is about to be fired, which can lead to more precise aiming and shooting.
- Reduced Trigger Creep: Trigger creep is the phenomenon where the trigger moves slightly forward after being pulled, causing the shot to be fired prematurely. The 2-stage design helps minimize this issue.
- Enhanced Comfort: The lighter first stage of the trigger makes it more comfortable to pull, especially during extended shooting sessions.
- Customization: Many 2-stage AR triggers are adjustable, allowing shooters to fine-tune the pull weight and trigger response to their preferences.
Popular 2-Stage AR Triggers
Several manufacturers produce 2-stage AR triggers, each with its unique features and benefits. Here are a few popular options:
- Geissele SSA: Known for its durability and consistent performance, the Geissele SSA is a favorite among competitive shooters and law enforcement officers.
- DPMS LR-308: This trigger is designed specifically for the LR-308 rifle and offers a smooth, consistent pull weight.
- Timney AR-5: The Timney AR-5 is a popular choice for shooters looking for a high-quality, adjustable trigger with a wide range of pull weights.
Conclusion
In summary, a 2-stage AR trigger is a valuable addition to any semi-automatic rifle. Its unique design and performance offer several advantages, including improved accuracy, reduced trigger creep, enhanced comfort, and customization options. Whether you’re a competitive shooter, a hunter, or a recreational shooter, a 2-stage AR trigger can help you achieve better results on the range.
