How to Choose the Best AR-15 Buffer Tube
Irrespective of whether you are an AR-15 buffer tube for the first time or looking for an upgrade, below are the key things to consider before you make any purchase.
Mil-Spec vs. Commercial Spec
There are two main standards for buffer tubes: Mil-Spec and Commercial-Spec.
Mil-Spec buffer tubes have a slightly smaller diameter and are more standardized. On the other hand, Commercial-Spec buffer tubes have a slightly larger diameter. So, ensure that you settle for a buffer tube that matches your lower receiver’s specifications.
Length
The length of buffer tubes varies from one model to the other to accommodate various stock configurations. The most common lengths are rifle-length (A2), carbine-length, and pistol-length. Choose a length that not only fits your intended setup but also matches your desired length of pull.
Construction Quality
Like any other gun component, the construction quality of buffer tubes determines their overall durability. The best AR-15 buffer tube is made with high-quality materials such as aircraft-grade aluminum. Such tubes stand out in terms of durability and longevity. Besides, they are relatively lightweight so the buffer tube won’t add unnecessary weight to your rifle setup.
Fixed vs Adjustable Tubes
Buffer tubes for AR-15 can be either fixed or adjustable. Choosing between the two types is largely a matter of individual preference. Adjustable buffer tubes allow you to change the length of pull by adjusting the stock position, providing more versatility. On the other hand, fixed buffer tubes have a set length.
Weight
Weight is the other important feature to take into consideration. Opt for the lightest buffer tube you can get, especially if you’re building a lightweight AR-15. It will hardly add any bulk that can interfere with the rifle’s performance. Light tubes are also more effective at absorbing recoil.
Cost
It is also important to pay attention to the cost. The best AR-15 buffer tube is one that meets your budget without compromising quality and performance. Since these tubes are available at various price points, consider your budget while balancing quality and features. Keep in mind that investing in a higher-quality buffer tube can contribute to the overall reliability and performance of your rifle.

- What length buffer tube do I need for my AR-15?
The length of the buffer tube you need depends mainly on the type of stock you plan to use. Most AR-15s use a rifle-length (A2) or carbine-length buffer tube.
