Understanding the AR-15 Heavy Trigger Spring: A Comprehensive Guide
When it comes to enhancing the performance of your AR-15 rifle, one of the most effective upgrades you can make is to replace the factory trigger spring with a heavier one. This simple modification can significantly improve the trigger pull weight, making your rifle more responsive and enjoyable to shoot. In this article, we will delve into the details of the AR-15 heavy trigger spring, exploring its benefits, installation process, and compatibility with various trigger systems.
Benefits of a Heavy Trigger Spring
One of the primary advantages of using a heavy trigger spring is the reduction in trigger pull weight. The factory trigger spring in most AR-15s is designed to provide a light, crisp trigger pull, which is great for rapid firing and accuracy. However, for some shooters, this light pull can be too sensitive and cause them to pull the trigger too quickly, leading to missed shots or poor accuracy.
By replacing the factory spring with a heavier one, you can achieve a more consistent and controlled trigger pull. This can help improve your shooting accuracy, especially at longer distances. Additionally, a heavier trigger pull can be beneficial for shooters who are prone to flinching or have a tendency to pull the trigger too quickly.
| Factory Trigger Spring | Heavy Trigger Spring |
|---|---|
| Light pull weight (typically around 4-6 lbs) | Heavier pull weight (typically around 6-8 lbs or more) |
| May cause flinching or rapid trigger pull | Improves consistency and control |
| Good for rapid firing and accuracy | Excellent for long-range shooting and precision |
Choosing the Right Heavy Trigger Spring
Selecting the appropriate heavy trigger spring for your AR-15 is crucial to ensure optimal performance. There are several factors to consider when choosing a spring, including the desired pull weight, trigger system compatibility, and the type of shooting you plan to do.
Trigger pull weight is a personal preference, but a common range for a heavy trigger spring is between 6-8 lbs. This weight provides a good balance between responsiveness and control. However, some shooters may opt for even heavier springs, such as 8-10 lbs, for increased precision and control.
Trigger system compatibility is also essential. Different trigger systems may require specific spring sizes and materials. For example, some trigger systems may require a stiffer spring to achieve the desired pull weight, while others may work well with a softer spring. It’s important to consult the manufacturer’s specifications or seek advice from an experienced gunsmith to ensure compatibility.
Installation Process
Installing a heavy trigger spring is a relatively straightforward process, but it does require some basic tools and knowledge. Here’s a step-by-step guide to help you through the installation process:
- Disassemble your AR-15 trigger group by removing the magazine catch, bolt catch, and safety selector.
- Remove the trigger and disconnect the hammer from the trigger bow.
- Remove the factory trigger spring and replace it with the new heavy trigger spring.
- Reassemble the trigger group, ensuring that the hammer is properly seated on the trigger bow.
- Test the trigger pull weight to ensure it meets your requirements.
It’s important to note that installing a heavy trigger spring may require some trial and error to achieve the desired pull weight. If the pull weight is too heavy, you may need to replace the spring with a lighter one or adjust the trigger sear. If the pull weight is too light, you may need to replace the spring with a heavier one or adjust the trigger sear.
Conclusion
Upgrading your AR-15 with a heavy trigger spring can significantly improve your shooting experience. By reducing trigger pull weight and providing a more consistent and controlled pull, a heavy trigger spring can help you achieve better accuracy and precision. When selecting a spring, consider the desired pull weight, trigger system compatibility, and the type of shooting you plan to do. With the right spring and some basic tools, you can easily install a heavy trigger spring and enjoy the benefits of a more responsive and accurate rifle.
