2. Spring Compression
Spring compression plays a crucial role in the proper function of an AR-platform rifle’s fire control group, directly influencing trigger pull weight, reset, and overall reliability. While proper spring direction ensures the force is applied correctly, the degree of compression determines the magnitude of that force. This intricate relationship between compression and direction is essential for achieving consistent and predictable trigger behavior.
-
Trigger Pull Weight:
The amount of compression directly affects the force required to pull the trigger. Higher compression results in a heavier trigger pull, while lower compression leads to a lighter pull. Finding the optimal compression is crucial for balancing shooter preference with reliable ignition. Too light a pull can increase the risk of accidental discharge, while too heavy a pull can negatively impact accuracy.
-
Trigger Reset:
Sufficient spring compression is necessary for reliable trigger reset. After firing, the spring pushes the trigger forward, allowing it to re-engage with the sear. Inadequate compression can result in a sluggish reset or failure to reset altogether, preventing follow-up shots. Conversely, excessive compression can make the reset feel overly stiff or contribute to binding within the trigger mechanism.
-
Hammer/Striker Impact:
Spring compression indirectly influences the force with which the hammer or striker impacts the firing pin. While the hammer spring primarily governs this force, the trigger spring’s influence on sear engagement and release timing can affect the hammer’s travel and thus its impact. Proper compression helps ensure consistent and sufficient force for reliable ignition.
-
Component Wear and Tear:
Incorrect spring compression can accelerate wear and tear on trigger components. Excessive compression places undue stress on the spring, trigger, and disconnector, potentially leading to premature failure. Insufficient compression, on the other hand, may cause inconsistent engagement and increased friction, also contributing to wear. Correct compression optimizes component life and maintains reliable function over time.
Understanding the relationship between spring compression and direction is fundamental for proper AR trigger function. Balancing these factors ensures reliable ignition, consistent trigger pull, and predictable reset, ultimately contributing to safe and accurate firearm operation.
