Why I Believe Ar 15 Barrel Shims are Necessary

As a gun enthusiast and owner of an AR 15 rifle, I have come to understand the importance of barrel shims. At first glance, they may seem like a minor and insignificant component, but in reality, they play a crucial role in the overall performance of the rifle.

One of the main reasons why barrel shims are necessary is to achieve proper alignment between the barrel and the receiver. Any misalignment can lead to accuracy issues and even potential safety hazards. The shims help to adjust and fine-tune this alignment, ensuring that the barrel is perfectly centered in relation to the receiver.

Another reason for using barrel shims is to mitigate any potential issues with headspace. Headspace refers to the distance between the bolt face and the chamber of a firearm when it is closed. If this distance is too large or too small, it can affect the functioning of the gun and cause malfunctions. By using shims, you can adjust and achieve optimal headspace for your AR 15.

Furthermore, barrel shims also play a crucial role in reducing recoil. By properly aligning and securing the barrel with shims, you can minimize any movement or shifting during firing, resulting in

My Buying Guide on ‘Ar 15 Barrel Shims’

As a gun enthusiast, I have gone through the process of purchasing and installing barrel shims for my AR 15 multiple times. Through my experience, I have learned the importance of selecting the right barrel shims for optimal performance and accuracy. In this buying guide, I will share my knowledge and tips on purchasing AR 15 barrel shims.

What are AR 15 Barrel Shims?

AR 15 barrel shims are thin, metal washers that are used to properly align the barrel of your rifle with the upper receiver. They are typically made of stainless steel or aluminum and come in various thicknesses. The purpose of using barrel shims is to allow for precise adjustments to achieve better accuracy and reduce any play between the barrel and receiver.

Why Do You Need AR 15 Barrel Shims?

Even with high-quality manufacturing, some AR 15 rifles may have slight misalignments between the upper receiver and barrel. This can result in inconsistent accuracy and affect your shooting experience. Installing barrel shims can address this issue by ensuring a tight fit between the two components, resulting in improved accuracy.

Moreover, if you are building your own custom AR 15 rifle from scratch, using barrel shims can help you achieve a perfect alignment between the upper receiver and barrel.

Factors to Consider When Buying AR 15 Barrel Shims

1. Material: The most common materials used for making barrel shims are stainless steel and aluminum. Stainless steel is more durable but also more expensive than aluminum.

2. Thickness: Barrel shims come in various thicknesses ranging from .001 inches to .020 inches. The thickness you choose will depend on your specific rifle’s needs, so it’s essential to measure your rifle’s gap before making a purchase.

3. Compatibility: Not all barrel shims fit all AR 15 rifles. It’s crucial to ensure that the shim you choose is compatible with your specific rifle model.

4. Brand Reputation: With so many options available in the market, it’s always a good idea to go for trusted brands that have a good reputation among gun enthusiasts.

Tips for Installing AR 15 Barrel Shims

1. Properly clean the upper receiver and barrel before installation.

2. Use a torque wrench to tighten the shim screws evenly to avoid any warping or misalignment.

3. Start with thinner shims first and add thicker ones if needed until you achieve proper alignment.

4. Double-check alignment after tightening by gently pushing down on the gas block while looking at the gap between the gas block and handguard.

In Conclusion

AR 15 barrel shimming may seem like a small detail, but it can make a significant difference in your rifle’s performance and accuracy. By considering factors such as material, thickness, compatibility, and brand reputation when purchasing shims, you can ensure that you get high-quality products that will improve your shooting experience. Remember to take your time during installation and always double-check alignment before finalizing everything.
