The seemingly insignificant AR-15 stock spring plays a crucial role in the reliable function of your firearm. Understanding its purpose, common issues, and replacement process is vital for maintaining a properly functioning and safe rifle. This comprehensive guide will delve into everything you need to know about AR-15 stock springs.
Understanding the AR-15 Stock Spring's Role
The AR-15 stock spring, often overlooked, is a critical component of the buttstock assembly. Its primary function is to provide the necessary tension to keep the buffer tube firmly in place and the stock securely attached. This seemingly simple task is paramount for several reasons:
-
Maintaining Stock Stability: The spring ensures the stock remains firmly connected to the receiver extension (buffer tube), preventing movement or looseness during firing. A weak or broken spring can lead to instability, impacting accuracy and potentially causing discomfort or injury.
-
Buffer Tube Retention: The spring works in conjunction with the buffer retainer to keep the buffer tube securely attached to the lower receiver. Without sufficient spring tension, the buffer tube could become dislodged, leading to malfunction.
-
Smooth Stock Deployment: In collapsible stocks, the spring contributes to a smooth and reliable extension and retraction of the stock. A properly functioning spring ensures a firm and consistent locking mechanism.
Common Problems with AR-15 Stock Springs
While generally durable, AR-15 stock springs can eventually wear out or break due to repeated use and exposure to the elements. Here are some common issues you might encounter:
-
Weakened Spring: Over time, the spring loses its tension, resulting in a loose stock and potential instability during firing. This is often noticeable by a loose or wobbly feel of the stock.
-
Broken Spring: In more extreme cases, the spring might break completely, rendering the stock unusable. This can occur due to fatigue, improper installation, or damage from external forces.
-
Corrosion: Exposure to moisture and other environmental factors can lead to corrosion, compromising the spring's integrity and function.
Identifying the Need for Replacement
Several signs indicate that your AR-15 stock spring might need replacing:
- Loose Stock: If your stock feels loose or wobbly, it's a strong indicator of a weakened spring.
- Difficult Stock Deployment/Retraction: In collapsible stocks, difficulty extending or retracting the stock could point to a problem with the spring.
- Visible Damage: Inspect the spring for any signs of damage, including cracks, breaks, or significant corrosion.
Replacing Your AR-15 Stock Spring: A Step-by-Step Guide
Replacing an AR-15 stock spring is a relatively straightforward process. However, always prioritize safety and ensure you are familiar with the proper procedures before attempting any repairs. (Note: Specific steps may vary slightly depending on your stock type. Refer to your firearm's manual for detailed instructions if needed.)
