Ar 15 Not Ejecting Casing: A Comprehensive Guide
When you encounter an AR-15 that’s not ejecting casings, it can be a frustrating experience. This issue can arise due to various reasons, ranging from simple malfunctions to more complex problems. In this article, we will delve into the possible causes and solutions for this problem, ensuring that you can diagnose and fix it effectively.
Understanding the Ejection System
The ejection system of an AR-15 is a critical component that ensures the smooth operation of the firearm. It consists of several parts, including the ejection port, extractor, extractor spring, and ejection port cover. Understanding how these parts work together is essential in troubleshooting ejection issues.
| Part | Description |
|---|---|
| Ejection Port | The opening at the top of the receiver where spent casings are ejected. |
| Extractor | A spring-loaded device that pulls the spent casing out of the chamber. |
| Extractor Spring | Provides the force necessary for the extractor to pull the casing out of the chamber. |
| Ejection Port Cover | Protects the ejection port and prevents debris from entering the receiver. |
Now that we have a basic understanding of the ejection system, let’s explore the common reasons why your AR-15 might not be ejecting casings.
Common Causes of Ejection Issues
1. Malfunctioning Extractor
The extractor is responsible for pulling the spent casing out of the chamber. If the extractor is worn, bent, or not properly seated, it may not function correctly. Inspect the extractor for any signs of damage or wear, and replace it if necessary.
2. Improperly Seated Extractor Spring
The extractor spring provides the force necessary for the extractor to pull the casing out of the chamber. If the spring is not properly seated, it may not exert enough force. Ensure that the spring is seated correctly and that the extractor is fully engaged with the spring.
3. Debris in the Ejection Port
Debris, such as dirt, grime, or spent casings, can accumulate in the ejection port and interfere with the ejection process. Clean the ejection port thoroughly to remove any debris.
4. Incorrectly Fitted Magazines
Using a magazine that is not properly fitted to your AR-15 can cause ejection issues. Ensure that the magazine is seated correctly and that the follower is free to move smoothly.
5. Worn or Bent Follower
The follower is a spring-loaded component that feeds rounds from the magazine into the chamber. If the follower is worn or bent, it may not feed rounds properly, leading to ejection issues. Inspect the follower for any signs of damage and replace it if necessary.
Diagnosing and Fixing Ejection Issues
1. Inspect the Extractor and Extractor Spring
Begin by inspecting the extractor and extractor spring. Check for any signs of damage, such as bending or wear. If the extractor is damaged, replace it with a new one. Ensure that the extractor spring is properly seated and that the extractor is fully engaged with the spring.
2. Clean the Ejection Port
Use a cleaning rod and a brush to clean the ejection port thoroughly. Remove any debris, such as dirt, grime, or spent casings, that may be interfering with the ejection process.
3. Check the Magazine and Follower
Inspect the magazine and follower for any signs of damage or wear. Ensure that the magazine is seated correctly and that the follower is free to move smoothly. If the follower is damaged, replace it with a new one.
4. Test the Firearm
After making the necessary repairs and cleaning, test the firearm to ensure that it is now ejecting casings properly. Load a magazine with ammunition and fire a few
