The seemingly insignificant AR-15 extractor spring plays a crucial role in the reliable function of your firearm. Understanding its purpose, common problems, and how to replace it is vital for any AR-15 owner, whether you're a seasoned shooter or a newcomer. This comprehensive guide will equip you with the knowledge to maintain your rifle's performance and ensure its continued safe operation.
The Role of the AR-15 Extractor Spring
The AR-15 extractor spring, a small but mighty component, is responsible for providing the necessary force to reliably extract spent cartridge casings from the chamber after firing. It works in conjunction with the extractor itself, a claw-like piece that grabs the spent casing's rim. Without a properly functioning spring, the extractor may not engage the casing firmly enough, leading to malfunctions.
Understanding the Extraction Process
The extraction process is a critical sequence of events:
- Firing: The round is fired, propelling the bullet downrange.
- Bolt Carrier Movement: The bolt carrier group (BCG) begins its rearward movement.
- Extractor Engagement: As the BCG retracts, the extractor, powered by the spring, grabs the spent casing's rim.
- Extraction: The extractor pulls the spent casing from the chamber.
- Ejection: The spent casing is then ejected from the weapon via the ejection port.
Common Problems and Signs of a Weak or Broken Extractor Spring
A weak or broken extractor spring can lead to a variety of malfunctions, including:
- Failure to Extract (FTE): The most common symptom is the inability of the extractor to remove the spent casing from the chamber. The round will be stuck, requiring manual clearing.
- Double Feeds: A weak spring might not extract the casing fully, resulting in a new round being loaded on top of the spent casing, leading to a dangerous jam.
- Stovepipes: The spent casing might be partially extracted but fails to clear the ejection port, creating a stovepipe jam.
Identifying a faulty spring usually involves observing these malfunctions during firing. If you experience any of these issues consistently, it's crucial to inspect the extractor spring. A visual inspection might reveal a broken, bent, or significantly weakened spring.
Replacing Your AR-15 Extractor Spring: A Step-by-Step Guide
Replacing the extractor spring is generally a straightforward process, but it requires careful attention to detail. Improper handling can damage other components. Always follow safety procedures and consult your firearm's manual.

The process typically involves:
- Disassembling the BCG: Carefully remove the bolt carrier group from the upper receiver.
- Removing the Extractor: The extractor is usually held in place by a spring and pin. The specific method will vary based on the manufacturer.
- Replacing the Spring: Carefully remove the old spring and replace it with a new one, ensuring proper orientation.
- Reassembling the BCG: Reassemble the BCG, paying close attention to the proper positioning of all components.
- Testing: Once reassembled, test-fire the rifle to verify proper function. Always follow safe firearm handling practices at a designated shooting range.
Choosing the Right Replacement Spring
When purchasing a replacement extractor spring, it's crucial to choose one specifically designed for your AR-15. Using an incorrect spring could lead to malfunctions or damage to your firearm. Always source parts from reputable manufacturers and suppliers.
Conclusion: Maintaining Your AR-15's Reliability
The seemingly minor AR-15 extractor spring is critical to the rifle's reliable operation. Understanding its function, recognizing the signs of failure, and knowing how to replace it are essential skills for any AR-15 owner. Regular maintenance and timely replacement of worn parts are key to ensuring the safety and continued performance of your firearm. Remember to always prioritize safety and consult your owner's manual before performing any maintenance or repair work.
