Why Upgrade Your AR-15 Trigger?
Factory Trigger Shortcomings
The factory trigger that comes standard in many AR-15s often leaves much to be desired. While functional, these triggers are frequently built to a budget, prioritizing cost over performance. This can manifest in a number of ways, ultimately hindering your shooting.
Factory triggers frequently suffer from a heavy pull weight. This means you need to apply a considerable amount of force to the trigger before it fires. This increased resistance makes it difficult to maintain a steady hold, especially when taking longer shots or during rapid-fire sequences. This heavy pull also makes it harder to feel the precise moment of trigger break, which is crucial for accurate shot placement.
Creep and slop are another common issue. Creep refers to the movement of the trigger before it breaks, and slop is the looseness or play in the trigger mechanism. Excessive creep and slop reduce the predictability of the trigger, making it harder to anticipate the break point and contribute to inconsistencies in shot placement.
The break itself might not be crisp and clean. Instead, it might feel mushy or uneven, further complicating the task of precisely controlling the shot. A clean, crisp break, on the other hand, provides immediate and predictable feedback, allowing for greater precision and faster follow-up shots.
All these factory trigger shortcomings combine to diminish accuracy. A heavy, gritty trigger makes it harder to maintain a stable sight picture, increasing the chances of pulling the shot. Inconsistent break points and excessive creep contribute to errors in shot placement.
Advantages of a Drop-In Trigger
The answer to these problems? A drop-in trigger offers a significant advantage. A drop-in trigger is a self-contained unit that houses the entire trigger mechanism, including the trigger, hammer, disconnector, and springs. It typically installs easily, without needing to take apart the lower receiver.
A drop-in trigger fundamentally enhances your experience by improving accuracy and precision. The smoother pull, cleaner break, and often lighter pull weight translate directly into tighter groups and more accurate shots. You’ll find yourself hitting your targets more consistently and with greater confidence.
The ease of installation is another major selling point. Installing a drop-in trigger is typically straightforward, even for those with minimal gunsmithing experience. This ease contrasts sharply with the often-complicated process of upgrading individual trigger components. You often need only a few basic tools, like a punch and hammer, and the instructions are generally clear and concise.
These units are often engineered with enhanced reliability in mind. High-quality materials and precision manufacturing contribute to a trigger mechanism built to withstand the rigors of frequent use, minimizing the chances of malfunctions. You can expect greater longevity from these trigger systems.
Finally, a drop-in trigger offers a markedly better trigger feel. A smoother, more consistent pull and a crisp, predictable break make the shooting experience more enjoyable and intuitive. This heightened responsiveness allows for more effortless trigger control, leading to improved accuracy and faster follow-up shots.
Key Features to Consider When Choosing a Drop-In Trigger
Selecting the right drop-in trigger can significantly improve your shooting. However, with so many options, it’s vital to consider several key features before making your decision.
Pull Weight
The pull weight of a trigger is a critical specification, often measured in pounds. It refers to the amount of force required to pull the trigger until the gun fires. The ideal pull weight varies depending on your intended use. For competition shooting, a lighter pull weight, perhaps between three and four pounds, allows for quick and precise shots. For defensive or tactical applications, a slightly heavier pull weight, between four and five pounds, might be preferred to reduce the risk of accidental discharges. Some triggers offer adjustable pull weights, allowing you to fine-tune the trigger’s feel to your preference and needs.
Trigger Break
The trigger break refers to the point at which the trigger releases the hammer, firing the round. A crisp and clean break is highly desirable. It means the trigger releases the hammer predictably and without any significant creep or mushiness. A clean break makes it easier to anticipate the shot and ensures that your sight picture remains stable at the moment of firing, enhancing accuracy. Avoid triggers that feel spongy or have a long, unpredictable break.
Reset
Reset is another essential factor. It refers to the distance the trigger travels after the shot until it resets and is ready to fire again. A short reset means the trigger requires less movement to reset, allowing for faster follow-up shots. This is particularly beneficial in dynamic shooting situations where quick follow-up shots are critical.
Trigger Style
The trigger style, whether it’s a curved or flat face, is a matter of personal preference. Some shooters find curved triggers more familiar and comfortable, while others prefer the straighter feel of a flat-faced trigger. Flat-faced triggers often provide a consistent contact point, potentially improving trigger control for some shooters. Consider what feels most natural and comfortable for your finger.
Materials and Construction
The materials and construction quality are critical to a trigger’s performance and longevity. Look for triggers manufactured from high-quality materials such as hardened steel or aircraft-grade aluminum. Coatings such as nickel boron, or Diamond-Like Carbon (DLC) can enhance durability and reduce friction, providing a smoother, more reliable trigger pull. A well-built trigger will withstand thousands of rounds and maintain its performance over time.
Installation Ease and Compatibility
The ease of installation and compatibility with your AR-15 are essential. Most drop-in triggers are designed for straightforward installation, often requiring only minimal disassembly of the lower receiver. Ensure the trigger you choose is compatible with your specific lower receiver. Review the manufacturer’s instructions for compatibility information and ensure that any special tools required are readily available.
Safety Features
Safety features are also important. Ensure that the trigger incorporates appropriate safety mechanisms, such as trigger safeties, to prevent accidental discharges. The trigger should function safely and reliably. If your AR-15 has an upgraded safety, make sure the trigger is compatible with the function of that safety selector.
