Understanding the AR-15 Trigger Reset Spring: A Comprehensive Guide

The AR-15 trigger reset spring is a crucial component of the firearm’s trigger assembly. This small yet vital part plays a significant role in the overall functionality and reliability of the AR-15 rifle. In this article, we will delve into the details of the trigger reset spring, its importance, and how it affects the shooting experience.

What is the AR-15 Trigger Reset Spring?

The AR-15 trigger reset spring is a coil spring that is responsible for resetting the trigger after it has been pulled. It is located between the trigger and the sear, and its primary function is to ensure that the trigger returns to its original position after being activated. This allows for a smooth and consistent trigger pull, which is essential for accurate shooting.

How Does the Trigger Reset Spring Work?

When you pull the trigger of an AR-15, the trigger reset spring is compressed. As the trigger is released, the spring pushes the trigger back to its original position. This process is crucial for maintaining consistent trigger pull weight and ensuring that the firearm can be fired repeatedly without any issues.

Here’s a step-by-step breakdown of how the trigger reset spring works:

• When you pull the trigger, the trigger reset spring is compressed.

• As the trigger is released, the spring pushes the trigger back to its original position.

• This action ensures that the trigger is reset and ready for the next shot.

Importance of the Trigger Reset Spring

The trigger reset spring is a critical component of the AR-15 trigger assembly. Here are some of the reasons why it is so important:

• Consistent Trigger Pull: The trigger reset spring ensures that the trigger pull weight remains consistent throughout the shooting process. This is essential for maintaining accuracy and consistency in your shots.

• Smooth Operation: A properly functioning trigger reset spring contributes to the smooth operation of the firearm. This makes the AR-15 more enjoyable to shoot and reduces the likelihood of operator fatigue.

• Reliability: The trigger reset spring plays a significant role in the overall reliability of the firearm. A failing spring can lead to inconsistent trigger pull weight, which can cause malfunctions and reduce accuracy.

Types of Trigger Reset Springs

There are several types of trigger reset springs available for the AR-15. Here are some of the most common types:

• Standard Trigger Reset Spring: This is the most common type of trigger reset spring and is typically included with most factory AR-15s.

• Lightweight Trigger Reset Spring: These springs offer a lighter trigger pull weight, which can be beneficial for rapid firing and long-range shooting.

• Heavyweight Trigger Reset Spring: These springs provide a heavier trigger pull weight, which can be advantageous for precision shooting and reducing the likelihood of accidental discharges.

How to Replace the Trigger Reset Spring

Replacing the trigger reset spring is a relatively straightforward process, but it requires some basic tools and knowledge of the AR-15’s trigger assembly. Here’s a step-by-step guide on how to replace the trigger reset spring:

1. Disassemble the firearm by removing the magazine, chamber flag, and bolt carrier group.

2. Remove the trigger assembly from the upper receiver.

3. Remove the trigger, hammer, and sear from the trigger assembly.

4. Remove the old trigger reset spring from the trigger assembly.

5. Install the new trigger reset spring into the trigger assembly.

6. Reassemble the trigger assembly and reinstall it into the upper receiver.

7. Reassemble the firearm and perform a function check.

Common Issues with the Trigger Reset Spring

Like any other component, the trigger reset spring can experience issues over time. Here are some common problems that can occur with the trigger reset spring:

• Wear and Tear: Over time, the trigger reset spring can become worn and lose its tension, leading to inconsistent trigger pull weight.

• Breakage: In
