Understanding the AR-15 trigger spring's orientation is crucial for proper function and safe operation. This guide will clarify the correct direction and address common misconceptions, ensuring you can confidently assemble and maintain your AR-15.
Identifying the AR-15 Trigger Spring
The AR-15 trigger spring is a small but vital component. It's a relatively simple coil spring, but its directionality is critical. Before we delve into the direction, let's quickly identify the spring itself. It's typically located within the trigger group, positioned behind the trigger and interacting with the hammer. It’s a small, usually uncoated, spring.
Correct Orientation: The "Hammer-First" Principle
The key to understanding the AR-15 trigger spring’s direction is the "hammer-first" principle. The spring's orientation should allow it to exert force primarily on the hammer. Think of it this way: when the trigger is pulled, the spring should assist in the hammer's rearward movement, before it then moves back into its resting position.
Incorrect installation can lead to malfunction, potentially resulting in failure to fire or, worse, unintended discharge. This underscores the importance of paying close attention to spring orientation.
Visualizing the Installation
Imagine you're looking at the trigger group from the back. The spring should be oriented so the open end of the coil (the end with the larger diameter) faces the hammer. The smaller, tighter end of the coil is generally directed towards the trigger itself. This ensures the spring provides consistent, reliable force during trigger operation.
Troubleshooting Incorrect Spring Installation
If you've accidentally installed the spring incorrectly, you might encounter several issues. These include:
- Failure to fire: The hammer may not move sufficiently to strike the firing pin.
- Sluggish trigger pull: The spring’s resistance may be significantly altered, creating a heavy or uneven trigger pull.
- Erratic trigger function: The trigger may feel spongy, inconsistent, or unreliable.
If you suspect incorrect spring orientation, disassemble the trigger group and carefully re-install the spring, paying close attention to the "hammer-first" principle as described above.
Beyond the Basics: Trigger Spring Variations
While the fundamental principle remains consistent, slight variations might exist depending on the specific trigger group manufacturer and model. However, the core concept – ensuring the spring's primary force is directed towards the hammer – should always apply. Always consult your firearm's manufacturer's instructions and diagrams for specific guidance on your model.
Safety First: Professional Assistance
While this guide provides valuable information, working with firearm components demands caution. If you're uncomfortable or unsure about any aspect of assembling or disassembling your AR-15, seek assistance from a qualified gunsmith. Safety should always be the top priority.
