AR-15 Spring: The Ultimate Guide to Choosing the Perfect One for Your Rifle

Featured in:

The AR-15 Spring is an essential component of the AR-15 platform. This spring plays a vital role in ensuring the smooth and reliable functioning of your rifle. It is often overlooked by many gun owners, but it can have a significant impact on your shooting experience.

Without the proper tension from the AR-15 spring, your firearm may not cycle correctly or may fail to eject spent casings. This can cause frustration and even safety concerns for shooters. Therefore, understanding this crucial part of your weapon is necessary to keep it in top working condition.

In this article, we will delve deeper into what an AR-15 spring is and how it works within your rifle's mechanism. We'll also discuss different types of springs available in the market today and their functions. By reading this article, you'll gain a better appreciation for just how important these small but mighty components are to firearms enthusiasts everywhere!

The AR-15 Spring: Understanding Its Importance in Your Rifle

As a gun enthusiast, you know that an AR-15 is more than just a rifle. It's an extension of yourself, and it deserves the best components to perform at its peak potential. One of the most crucial parts of your rifle is the spring.

In this article, we will delve into everything there is to know about AR-15 springs. From their benefits to comparisons with other types of springs, as well as tips on how to maintain them properly.

The Basics: What Is an AR-15 Spring?

An AR-15 spring refers to one or several helical tension springs used in different parts within your rifle. They come in various lengths and strengths depending on their intended use.

A quick overview:

Type Location Used Purpose
Buffer Spring Inside Receiver Extension Tube (Buffer Tube) & Buffer Assembly Absorbs recoil energy from fired round; returns bolt carrier assembly forward after firing
Trigger Spring Trigger Group Affects trigger pull weight
Hammer Spring Hammer Group Makes sure hammer strikes rear of firing pin hard enough for ignition

Benefits Of Using An Upgraded / High-Quality Ar-15 Springs

The stock spring that comes with your gun may be adequate for casual users but upgrading it could lead to many improvements:

  1. Better accuracy – Quality buffer springs can reduce muzzle rise and provide better stability during rapid fire.
  2. Consistent cycling – This means less jamming while shooting.
  3. Faster follow-up shots – As mentioned earlier, quality buffer springs will reduce muzzle rise which makes acquiring targets faster.
  4. Improved reliability – Performance upgrades using high-quality trigger/hammer/spring kits often result in smoother operation improving overall reliability
    5.Improved Longevity – replacing factory or worn-out lower parts springs with enhanced aftermarket alternatives is an important part of rifle maintenance that can extend the life of this critical component.

Comparing different types of AR-15 Springs

There are many types of springs available in the market, each claiming to be better than others. Let's discuss some commonly used ones:

Type Description
Mil-Spec Spring This is the standard spring that comes with your gun. It works well for most casual users but has a limited lifespan and may not perform well under stress.
Chrome Silicon Spring Made from silicon wire, they have better longevity and cycling than mil-spec variants.
Cryogenically Treated Springs Makes use of extreme cold to improve durability by nearly 300%, which means fewer replacements are needed over time.

Tips For Maintaining Ar-15 Springs

  1. Lubrication: Keep your gun lubricated regularly as this will prevent dust, soil or other debris from getting inside and causing damage to internal components including springs.

  2. Check for wear & tear: Always keep an eye out for any signs of wear-and-tear on your riffle’s lower parts kit when cleaning it after use or during inspection before firing again.

  3. Replacement Schedule: Have an accurate replacement schedule in place as per manufacturer recommendations based on usage patterns (round count), climate conditions, environment etc.To avoid potential breakdowns during high-stress situations.


An AR-15 spring is one small yet critical piece within a complex machine – but its importance cannot be overstated when it comes to maintaining proper function and overall performance levels.The quality, type and condition all factor into how effective they really are in terms of reliability,durability,maintainance costs,time efficiency,and ultimately accuracy.A little bit more investment upfront can go a long way towards improving firearm operation,safety,reliability,longevity,resale value, and overall enjoyment of the shooting sport. So be sure to choose your springs wisely!


What is an AR-15 spring and what purpose does it serve in the rifle?

The AR-15 spring is a small but crucial part of the popular semi-automatic rifle. It's responsible for several important functions in the firearm, including powering its action and ensuring that it cycles properly.

One of the most important roles that an AR-15 spring plays is to provide tension against other parts within the gun, such as bolts or buffers. In simple terms, this tension ensures that when one part moves backwards during cycling, there's enough force from another Spring to push them back into place afterwards.

Springs also help absorb recoil by absorbing energy from firing rounds. This helps prevent damage to other parts of the firearm over time.

In some cases, depending on modifications made by individual users or manufacturers – there may be more than one type of spring within an AR-15 gun.

What are different types of springs used in an AR-15 rifle?

There are many types of springs used in various components throughout an AR-15 rifle – each serving a specific function.

Some common types include buffer springs (which sit inside buffer tubes), extractor springs (used with extractors), magazine catch springs (keep magazines locked into place) and trigger/hammer Springs which allow for smooth movement with minimal resistance between these two critical components.

Other vital areas where you'll find Springs include gas blocks/gas tubes – where they work alongside pistons to regulate pressure along barrels – helping both accuracy and efficiency while reducing maintenance required over time.

How often should I replace my Ar 15 Springs?

AR 1an5s pring life can vary widely depending on how frequently you use your firearm or how heavily modified it may be compared to stock models offered by manufacturers.
If you're using your gun often at ranges or for home defense purposes; generally speaking – you'll want to have spare replacement Springs available at all times if possible.

To determine when it's time to replace your AR-15 springs, you should keep an eye out for any changes in the rifle's performance or handling. If you notice issues with cycling or feeding, trigger reset (or lack thereof), accuracy problems – then that could be a signal that it’s time to check and see if the spring needs replacement.

As a general rule of thumb – replacing Springs every 5000 rounds is something most gun enthusiasts recommend, but this varies depending on manufacturer recommendations as well as use cases.

Can I upgrade my AR-15 springs?

Yes! Upgraded Springs are available through aftermarket manufacturers and can provide some additional benefits over factory stock parts.
For example – aftermarket buffer springs may be stronger than their factory equivalents which can help reduce muzzle rise by providing more resistance against recoil forces generated during firing.

However, remember that not all upgraded options will fit perfectly into your firearm without modification so consult with experts before making any replacements.

Another thing worth noting is how much modification has been done to your firearm already; installing heavier/better quality Springs may require extra power from other components in order for everything to function optimally together.

Are there any downsides of having worn-out Ar 15 Spring?

If left unchecked over longer periods – yes.
Worn-out or malfunctioning AR-15 springs won't provide the same level of tension required within the weapon itself as they begin losing their ability to properly push back components into place after being fired due either reduced strength/capacity from repeated use (fatigue) OR physical damage incurred.
This can cause malfunctions like failure-to-feed/failure-to-cycle/failure-to-eject, misfires and worse – putting both users & bystanders at risk during operation.
In extreme cases where these critical failures present themselves under normal operating conditions like competitions/home defense scenarios etc., permanent damage may occur leaving owners with non-functional firearms unless maintenance/repairs are undertaken immediately.
