Trigger Spring-Related Trigger Issues
Common trigger issues stemming from the spring include erratic trigger pull, inconsistent trigger resets, and a hard or overly sensitive trigger. These problems can significantly impact shooting accuracy and enjoyment. Knowing the underlying causes can save you a lot of trouble.
Possible Causes of Trigger Issues
A worn or broken spring is a frequent culprit. Excessive use, improper maintenance, or a spring that’s been subjected to extreme temperatures or impacts can lead to fatigue and breakage. Misaligned components, such as the trigger itself or the trigger housing, can also cause inconsistent or jerky trigger pulls. Furthermore, a spring that is either too weak or too strong can lead to various issues.
Finding the AR-15 trigger spring’s precise location can be a bit of a quest, but it’s crucial for proper function. Knowing where it resides is key for any gun enthusiast, and a good understanding of firearms is vital. For a different perspective on firearm mechanics, check out the Stevens Model 94 20 gauge here.

Diagnostic Methods for Trigger Spring Problems
A thorough visual inspection is often the first step. Check the spring for any obvious signs of damage, such as cracks, kinks, or breaks. Inspect the trigger mechanism for any misalignment or foreign debris that might be hindering the spring’s function. Additionally, systematically check for excessive wear or damage to the trigger housing.
Faulty Spring Behavior and Corresponding Symptoms, Ar15 trigger spring location
A weak spring will often result in a heavy, gritty trigger pull, and a very long trigger travel. Conversely, a spring that’s too strong can lead to a very short trigger pull, or a trigger that is too sensitive and may not reset properly. A broken spring will typically result in a complete failure to fire.
Comparison of Trigger Spring Types and Performance
Different trigger springs are designed for various firearm models and shooting styles. Higher-end springs, for example, often incorporate materials with higher tensile strength for enhanced performance. Lower-end springs, or those with less durable materials, may lead to quicker wear and tear. This is a crucial consideration when making decisions on replacement springs.
| Spring Type | Typical Performance | Potential Issues |
|---|---|---|
| High-strength steel | Smooth, consistent trigger pull; reduced wear | Can be more expensive |
| Mild steel | Acceptable performance; more affordable | May exhibit more wear and tear over time |
Trigger Spring Specifications and Variations
The heart of a smooth and reliable trigger is often the humble trigger spring. Understanding its specifications and variations is crucial for any AR-15 enthusiast looking to optimize their firearm’s performance. This section dives deep into the specifics, from standard measurements to the impact of different spring designs.Trigger springs in AR-15s are vital components influencing trigger pull weight and reset.
Different spring types, each with unique characteristics, offer varying degrees of responsiveness. Choosing the right spring can drastically affect the shooting experience.
Standard Specifications
Trigger springs are typically rated by their spring rate, a measure of the force required to compress the spring a given distance. This rate is often expressed in pounds per inch (lbs/in). Standard lengths and wire gauges are also critical parameters. Variations in these specifications can significantly impact the overall trigger performance.
Differences Between Trigger Spring Types
Various trigger spring types cater to different preferences and shooting styles. Some springs are designed for lighter trigger pulls, while others prioritize a crisp reset. A spring’s hardness, or its resistance to compression, is directly related to the force it applies. This hardness, in turn, influences the trigger’s pull weight and how quickly the trigger returns to its initial position.
Comparative Analysis of Trigger Spring Types
The table below highlights key characteristics of different trigger spring types.
| Spring Type | Spring Rate (lbs/in) | Length (inches) | Wire Gauge | Typical Application |
|---|---|---|---|---|
| Standard | ~10-15 | ~0.75 | ~0.040 | General purpose, balanced trigger pull |
| Heavy Duty | ~16-20 | ~0.75 | ~0.040 | For users who prefer a heavier trigger pull, or for enhanced durability |
| Light Duty | ~8-12 | ~0.75 | ~0.040 | For users seeking a lighter trigger pull, potentially sacrificing durability |
The table provides a general overview. Specific values may vary depending on the manufacturer and the specific AR-15 model.
Variations Based on Manufacturers and Models
Different manufacturers employ various spring designs to achieve their desired trigger characteristics. Some might use specialized materials or coil configurations to enhance the spring’s performance. Different AR-15 models may also feature trigger springs tailored to their specific design, optimizing for the unique geometry of the trigger mechanism. For example, a competition-grade AR-15 might use a spring with a higher spring rate for a precise trigger pull, whereas a hunting rifle might prioritize a smoother pull.
Impact of Spring Rates on Trigger Performance
A higher spring rate generally results in a heavier trigger pull. This heavier pull can be desirable for some shooters who prefer a more positive trigger engagement. However, an overly high spring rate can lead to a less responsive or less enjoyable shooting experience. Conversely, a lower spring rate typically results in a lighter trigger pull but can compromise the trigger’s crisp reset, making the gun feel less precise.
The optimal spring rate is often a balance between these two factors.
