Installation Process
If you have no gunsmithing skills, then you don’t have to worry about installing a buffer tube. Most of the buffer tubes that we put on here are easy to install. All it takes are the right tools and a few minutes of your time in order for you to install one properly.

Frequently Asked Questions (FAQ)
Here are some frequently asked questions (FAQs) some people may have.
Q: What is a Buffer Tube and What Are They Used For?
A buffer tube is another term for a receiver extension. This is a protuberance that sticks out of your AR-10 rifle. The buffer tube is made to serve 2 purposes. Firstly, it will house what is known as the recoil buffer apparatus. Second, it also serves as an accessory to your rifle’s buttstock.
Inside a buffer tube, there is a large spring that is also known as an action spring. This spring comprises the recoil buffer mechanism inside. The buffer tube allows the bolt, buffer tube, and spring itself to go in the tube flattened and shoot itself forward.
Q: Are AR-15 and AR-10 Buffer Tubes The Same?
The quick answer: no. To give you an even drawn-out answer, almost all the parts of a buffer tube may not be compatible with each other. In simple words, an AR-15 buffer tube may not be able to work properly in an AR-10 rifle and vice versa. The tube lengths, however, are similar. But other than that, the parts like the lower parts or the rail system will not be compatible with any other AR-style rifle other than its own.
However, some parts like the buttstock, hammer, or pistol grip are most likely well-matched for either an AR-15 or AR-10.
