AR-15 Trigger Not Resetting: A Comprehensive Guide

When you encounter an AR-15 trigger that’s not resetting, it can be a frustrating experience. This issue can arise due to various reasons, and understanding the problem is the first step towards resolving it. In this article, we will delve into the possible causes, symptoms, and solutions for an AR-15 trigger that’s not resetting.

Understanding the AR-15 Trigger Mechanism

The AR-15 trigger mechanism is a complex assembly that includes the trigger, hammer, sear, and disconnect. When the trigger is pulled, it releases the hammer, which in turn strikes the primer of the cartridge, causing the firearm to fire. The trigger reset is the point where the trigger returns to its original position after being pulled. If the trigger doesn’t reset, it can lead to malfunctions and unsafe conditions.

Common Causes of AR-15 Trigger Not Resetting

There are several reasons why your AR-15 trigger might not reset properly. Here are some of the most common causes:

• Debris or dirt in the trigger assembly

• Worn-out or damaged parts, such as the trigger, hammer, or sear

• Improper installation or adjustment of the trigger assembly

• Excessive tension on the trigger pull

Diagnosing the Problem

Before attempting to fix the issue, it’s essential to diagnose the problem correctly. Here are some steps you can follow:

1. Inspect the trigger assembly for any visible debris or dirt. Clean the assembly with a soft brush and compressed air.

2. Check for worn-out or damaged parts. If you find any, replace them with new ones.

3. Ensure that the trigger assembly is properly installed and adjusted. Refer to the manufacturer’s manual for instructions.

4. Check the trigger pull tension. If it’s too tight, it can prevent the trigger from resetting. Adjust the tension as needed.

Fixing the AR-15 Trigger Not Resetting Issue

Once you’ve diagnosed the problem, you can proceed with the following solutions:

1. Remove the magazine and ensure the firearm is unloaded.

2. Disassemble the trigger assembly according to the manufacturer’s instructions.

3. Inspect the parts for any signs of wear or damage. Replace any worn-out or damaged parts.

4. Check the trigger pull tension and adjust it if necessary.

5. Reassemble the trigger assembly and ensure that all parts are properly aligned.

6. Test the trigger to ensure that it resets correctly.

Preventing Future Issues

Preventing future issues with your AR-15 trigger involves regular maintenance and proper handling. Here are some tips:

• Keep your firearm clean and free of debris.

• Perform regular maintenance, such as lubricating the moving parts.
