The Importance of AR15 Barrel Nut Shims

As an avid shooter and owner of multiple AR15 rifles, I have come to understand the importance of using barrel nut shims. These small metal shims may seem insignificant, but they play a crucial role in ensuring the proper alignment and stability of the barrel on your AR15.

One of the main reasons why barrel nut shims are necessary is to achieve a tight and secure fit between the barrel and upper receiver. The barrel nut is responsible for holding these two components together, and any movement or looseness can affect accuracy and performance. By using shims, you can eliminate any gaps or unevenness between the two parts, resulting in a more stable platform.

Moreover, barrel nut shims also help with proper gas tube alignment. The gas tube is responsible for cycling the rifle’s action, and if it is misaligned or bent due to an improperly tightened barrel nut, it can cause malfunctions or even damage to your rifle. Shims ensure that the gas tube is perfectly aligned with the gas port on the barrel, allowing for smooth operation.

In addition to these functional benefits, using barrel nut shims can also aid in achieving better accuracy. A properly aligned and secured barrel reduces any potential stress on

My Buying Guide on ‘Ar15 Barrel Nut Shims’

Introduction

As an avid gun enthusiast, I have spent countless hours researching and trying out different parts for my AR15. One crucial component that often gets overlooked is the barrel nut shims. These small pieces play a significant role in the accuracy and performance of your rifle. In this buying guide, I will share my knowledge and experience to help you make an informed decision when purchasing AR15 barrel nut shims.

Understanding Barrel Nut Shims

Before diving into the buying guide, it is essential to understand what barrel nut shims are and their purpose. Barrel nut shims are thin metal washers that are placed between the barrel nut and the receiver of an AR15 rifle. They help in aligning the barrel with the upper receiver, ensuring proper headspacing and accuracy. Without these shims, there can be excess play between the two components, resulting in a decrease in accuracy.

Factors to Consider

When looking for AR15 barrel nut shims, there are a few factors that you should keep in mind:

1. Material: The most common materials used for barrel nut shims are stainless steel or aluminum. Both materials are lightweight and durable, but aluminum tends to be softer and may wear out faster than stainless steel.

2. Thickness: Barrel nut shims come in various thicknesses ranging from 0.001 inches to 0.010 inches. The thicker the shim, the more it will affect headspacing and potentially affect accuracy.

3. Compatibility: It is crucial to ensure that the barrel nut shim you choose is compatible with your specific AR15 model. Some shims may not work with certain receivers or barrels due to differences in dimensions.

The Importance of Proper Headspacing

Headspacing refers to how well the bolt locks into place against the chamber of your rifle’s barrel when closed fully. A proper headspace is crucial for safety and accuracy when firing your rifle. If there is too much or too little headspace, it can cause malfunctions or even damage your firearm.

Benefits of Using Barrel Nut Shims

Now that we understand what barrel nut shims are let’s discuss why they are essential:

1. Improved Accuracy: As mentioned earlier, using barrel nut shims ensures proper headspacing, which results in better accuracy when shooting your AR15 rifle.

2. Increased Reliability: By properly aligning the barrel with the receiver using shims, you can reduce wear on various components such as bolts and extractors, leading to increased reliability of your firearm.

Conclusion

In conclusion, investing in high-quality AR15 barrel nut shims is crucial for any serious shooter who wants optimal performance from their rifle. Remember to consider factors such as material, thickness, and compatibility when making your purchase decision.
I hope this buying guide has been helpful in guiding you towards choosing the right barrel nut shim for your AR15 rifle.
