Why I Always Use AR15 Barrel Nut Shims

As an avid shooter and owner of multiple AR15 rifles, I have learned the importance of proper barrel installation. One key component in this process is the barrel nut. This small but crucial piece holds the barrel in place and ensures proper alignment with the upper receiver. However, even with proper torque and alignment, there can still be slight variations in how tightly the barrel nut sits against the receiver. This is where AR15 barrel nut shims come into play.

I first learned about barrel nut shims when I encountered issues with my AR15’s accuracy and consistency. After some research and consultations with experienced gunsmiths, I discovered that my barrel was not properly aligned due to a small gap between the barrel nut and upper receiver. This resulted in inconsistent pressure on the barrel, leading to inconsistent shots.

To fix this issue, I started using AR15 barrel nut shims during every barrel installation. These shims are thin metal washers that are placed between the upper receiver and barrel nut, filling any gaps and ensuring a snug fit. By doing so, I have noticed a significant improvement in my rifle’s accuracy and consistency.

Moreover, using barrel nut shims also helps prevent any potential damage to

My Buying Guide on ‘Ar15 Barrel Nut Shims’

As a gun enthusiast and owner of an AR15 rifle, I understand the importance of having the right accessories for optimal performance. One crucial accessory for an AR15 is the barrel nut shim. This small but essential component plays a vital role in ensuring the stability and accuracy 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.

What are AR15 Barrel Nut Shims?

Before diving into the buying guide, it is essential to understand what exactly AR15 barrel nut shims are and their purpose. Barrel nut shims are thin metal or plastic washers that are placed between the barrel nut and upper receiver of an AR15 rifle. They help to fill any gaps between these two components, providing a tighter fit and stabilizing the barrel.

Why do you need AR15 Barrel Nut Shims?

Having a stable barrel is crucial for consistent accuracy when shooting with an AR15 rifle. Over time, as you fire rounds through your rifle, there might be slight wear and tear on the upper receiver’s threads or barrel threads. This can cause a slight loosening of the barrel nut and affect the stability of your rifle’s barrel. By using barrel nut shims, you can compensate for this wear and tear and maintain a tight fit between the upper receiver and barrel.

Factors to consider when buying AR15 Barrel Nut Shims

When looking to purchase AR15 barrel nut shims, here are some essential factors to keep in mind:

Material

The most common materials used for making barrel nut shims are aluminum, stainless steel, or plastic. Aluminum shims are lightweight but durable, while stainless steel shims offer more strength but add weight to your rifle. Plastic shims may not be as durable as metal ones but can be easily replaced if needed.

Thickness

Barrel nut shims come in various thicknesses, ranging from 0.001 inches to 0.010 inches. The thickness you choose will depend on how much gap needs to be filled between your upper receiver and barrel.

Compatibility

Not all AR15 rifles have the same thread pitch or diameter for their upper receivers’ threads or barrels’ threads. It is crucial to check if the shim you are considering is compatible with your specific rifle model before making a purchase.

Where to buy AR15 Barrel Nut Shims?

You can find AR15 barrel nut shims at most gun stores or online retailers that specialize in firearm accessories. It is always recommended to purchase from reputable sellers who offer quality products at reasonable prices.

Conclusion

Investing in high-quality AR15 barrel nut shims is essential for maintaining stability and accuracy in your rifle’s performance. With this buying guide, I hope I have provided valuable insights into what factors to consider when purchasing these crucial components for your AR15 rifle. Remember always to do thorough research before making any purchases and opt for quality over price when it comes to firearm accessories.
