Types of AR-15 Buffer Tubes
There are two main types of AR-15 buffer tubes: mil-spec and commercial-spec.
Mil-Spec Buffer Tube: This type has a diameter of approximately 1.148 inches. It is the standard used by the military and most manufacturers. Mil-spec tubes are typically preferred for their consistency and compatibility with a wide range of stocks and accessories.
Commercial-Spec Buffer Tube: This type has a slightly larger diameter of approximately 1.168 inches. Commercial-spec tubes are usually less expensive but have fewer options for aftermarket stocks and accessories.
How to Choose the Best AR-15 Buffer Tube
Here are the key things to consider when shopping for the best AR-15 buffer tube.
Material and Construction
The material used to make a buffer tube determines its overall durability. Most buffer tubes are made from aluminum, with 7075-T6 being the most durable and commonly recommended for its strength and longevity. Another common aluminum is 6061-T6, which is still strong but not as durable as 7075-T6.
The other thing to consider is the finish. The best AR-15 buffer tube comes with a hard-anodized finish, which provides resistance to corrosion and wear.
Buffer Tube Length and Positions
Buffer tubes come in different lengths and with different numbers of adjustment positions. The standard AR-15 carbine buffer tube typically has 6 adjustment positions, which allows you to adjust the length of the pull. There are also buffer tubes with fewer or more positions.
Compatibility
Ensure the buffer tube is compatible with your lower receiver and stock. Mil-spec tubes are generally more universally compatible, while commercial-spec tubes may limit your choices for aftermarket parts.
Intended Use
Consider how you will use your AR-15. A carbine-length buffer tube is most common and suitable for most applications, including tactical and home defense. Rifle-length buffer tubes are used in fixed stock configurations and can offer different recoil characteristics.
Buffer and Spring
The buffer and spring play crucial roles in the function of your buffer system. Make sure to choose a buffer and spring that match your tube length and intended use (standard, heavy, etc.). Heavier buffers can reduce felt recoil and improve cycling reliability.
Price
Lastly, consider the price. While it’s important to stay within your budget, avoid overly cheap options that may compromise on quality. Balance cost with the features and reliability offered.
FAQs
- What is the purpose of the buffer tube?
The buffer tube houses the recoil buffer and buffer spring, which absorb recoil energy, cycling the firearm’s action and aiding in its function.
- What length buffer tube do I need?
It depends on your AR-15 configuration and intended use. Most AR-15s use a rifle-length buffer tube, but carbine and pistol-length tubes are also available for different setups.
- Do I need any special tools to install a buffer tube?
Installing a buffer tube typically requires basic tools like a castle nut wrench and an armorer’s wrench. Some buffer tube kits may include the necessary tools, but it’s a good idea to have them on hand.
