Single Stage vs. Two Stage AR15 Triggers: What's The Difference?


In the dynamic world of firearms, the AR-15 platform stands as an iconic symbol of versatility and customization. Among the many components that enthusiasts tweak to enhance performance, the trigger system holds a pivotal role. Two prevalent options for AR-15 triggers are the Single Stage and Two Stage triggers, each offering distinct advantages catering to specific preferences and applications. The market offers many mil-spec and drop-in upgrades to consider. If you're building an AR15 or considering an upgrade, you need to know what sets these two types of triggers apart.


Single Stage Triggers 


Single Stage triggers have a consistent pull weight throughout the entire trigger squeeze, providing a seamless and uninterrupted experience. Single Stage triggers are straightforward, with a single, continuous pull from start to release. This simplicity often translates to ease of use, making it an attractive option for beginners or those who prioritize uncomplicated functionality and unwavering reliability.  Ideal for scenarios requiring rapid and continuous shots, Single Stage triggers facilitate quicker follow-up shots. This makes them a preferred choice for applications such as competitive shooting and dynamic target engagement.


Generally, Single Stage triggers are more cost-effective than their Two Stage counterparts. This affordability makes them accessible to a broader range of gun owners, especially those entering the AR-15 customization realm.


Two Stage Triggers


Two Stage triggers have a distinct initial take-up, known as the first stage, followed by a distinct wall then "break" leading to the shot release, referred to as the second stage. The two-stage design allows for a more deliberate and controlled trigger pull. This precision is particularly advantageous in scenarios where accuracy is paramount, such as long-range shooting or precision competitions. Allowing the shooter to place the trigger on the "breaking point" using tactile feedback.  This in turn leads to enhanced trigger control. Shooters can gauge the amount of force required for the shot by feeling the first and second stages. This enhanced control is appreciated by marksmen who prioritize a predictable and consistent trigger pull.


Two Stage triggers often have a more defined wall before the break, reducing the likelihood of accidental discharges. This safety feature is valued by individuals who prioritize safety in various shooting environments.


Which Trigger is Right for You? Choosing the Right Trigger.


Competition Shooting


• Single Stage: Ideal for disciplines where speed is crucial, such as 3-Gun competitions, where rapid and accurate shots are essential.


• Two Stage: Suited for precision shooting competitions like PRS (Precision Rifle Series), where accuracy and controlled trigger pulls play a pivotal role.


Reliability and Duty Use


• Single Stage: Offers simplicity and reliability, making it a solid choice for duty use or self-defense scenarios.


• Two Stage: The enhanced control and safety features make it suitable for applications where a measured and controlled shot is imperative.


Ultimately, the choice between Single Stage and Two Stage triggers often boils down to personal preference. Those who prioritize simplicity, speed, and cost might lean towards Single Stage, while shooters valuing precision, control, and safety might opt for the Two Stage triggers.


In the diverse landscape of AR-15 customization, the trigger system remains a nuanced choice, allowing enthusiasts to tailor their firearms to their specific needs and shooting styles. Whether unleashing rapid volleys on the competition field or meticulously placing shots on distant targets, the AR-15 trigger, be it Single Stage or Two Stage, is a critical component in the pursuit of firearm perfection.
