The AR-15 platform's popularity stems from its modularity and adaptability. One often-overlooked component crucial to smooth, reliable operation is the trigger spring. While seemingly insignificant, upgrading this seemingly small part can significantly impact your rifle's performance, feel, and overall reliability. This guide delves into the reasons why an AR-15 trigger spring upgrade might be beneficial, the different types available, and what to consider when making your choice.
Why Upgrade Your AR-15 Trigger Spring?
A worn or weak trigger spring can lead to several problems:
- Creep: A sluggish or inconsistent trigger pull with a noticeable "creep" before the break. This affects accuracy and shot placement, particularly in precision shooting.
- Reset Issues: Difficulty in the trigger resetting after the shot, leading to potential malfunctions and delays in follow-up shots.
- Light Primer Strikes: Insufficient spring force might not provide enough energy to reliably ignite the primer, resulting in misfires.
- Increased Trigger Pull Weight: A weaker spring can sometimes lead to a heavier trigger pull than intended, negatively affecting trigger control and shooter comfort.
Types of AR-15 Trigger Springs
AR-15 trigger springs come in various strengths and materials, each affecting the trigger's feel and performance. Common options include:
-
Standard Springs: These are the factory-installed springs, providing the manufacturer's specified trigger pull weight and feel. They are often adequate for standard shooting but may not be optimal for competitive or precision shooting.
-
Enhanced Springs: These are designed to provide a more consistent and crisp trigger pull while maintaining reliability. They often improve reset speed and reduce creep. These are a good starting point for an upgrade.
-
Heavy Springs: Used in some specialized applications (e.g., suppressors), heavier springs help mitigate the increased pressure on the firing pin resulting from the added back pressure. They are usually not recommended for standard applications as they increase trigger pull weight.
Choosing the Right AR-15 Trigger Spring Upgrade
Selecting the proper spring depends on several factors:
- Your Shooting Style: Precision shooters often prefer a lighter, crisper trigger, while those focused on rapid fire might favor a slightly heavier spring for enhanced control.
- Your Rifle's Usage: Heavy-duty use (e.g., military or law enforcement) might necessitate a more robust spring compared to recreational shooting.
- Your Trigger Group: Some aftermarket trigger groups are designed to work optimally with specific spring weights. Check your manufacturer's specifications before upgrading.
Installation and Considerations
Installing an AR-15 trigger spring is generally straightforward but requires careful attention to detail. Consult a qualified gunsmith or a reputable online guide with detailed, illustrated instructions if you are not comfortable with disassembly and reassembly of firearm components. Improper installation can lead to malfunctions or even damage to your rifle.
Disclaimer: Always prioritize safety when working with firearms. Always ensure the firearm is unloaded and clear before handling any components. If you are unsure about any aspect of this process, seek the assistance of a qualified gunsmith.
Conclusion
Upgrading your AR-15 trigger spring can significantly enhance the performance and reliability of your rifle. However, proper research and careful selection are critical to achieving the desired results. By understanding the different types available and considering your specific needs, you can significantly improve your shooting experience. Remember to always handle firearms responsibly and safely.
