What is a Buffer Tube and What Are They Used For?
A buffer tube is associated with the buttstock. The buffer tube houses two key components: the buffer and the buffer spring. Another purpose of the tube is that it serves as an attachment end for your AR-15โs buttstock.
The purpose of the buffer tube is as space for the buffer to function as it's supposed to. The buffer itself is designed to help you resist a good amount of the rifleโs recoil. Most of these buffer tubes have adjustable positions which make the AR-15 more usable for the shooter.
How to Choose a Buffer For Your AR-15 Pistol
One of the most important skills to have when it comes to looking for a great buffer tube is distinguishing a great quality one from a crappy one, especially when it's your first time purchasing one. If anything, it's always good to get the opinion of those who have bought buffer tubes in the past. A lot of gun forums online have members talking about why they chose a certain buffer tube. But to save you time here's the list some of them have determined as "decision driving factors":
Material
Of course, the overall quality of the product will be based on the kind of material it's made from. Almost all gun manufacturers in the United States adhere to strict standards to ensure a buffer tube is made of the highest quality. Most of the time, aluminum will be the odds-on favorite.
More specifically, aircraft quality aluminum or 6061-T6 aluminum is the top materials of choice. Durability is an important factor, since these buffer tubes are not only designed to take beatings but if taken care of properly, will last many years.
Phase 5 Tactical - AR-15/M16 Pistol Buffer Tube is made of Aluminum, hardcoat anodized.
Price
As a budget shopper, almost every purchase will be based on price. And we wonโt blame you if youโre one of the many that do. There are a ton of gun accessories that are high in quality and carry an affordable price tag. Your mission is to find the same in an AR-15 pistol buffer tube, particularly if youโre also a first-time buyer as well. Remember to pay close attention to what the tube is made of and how long it will likely last.
Standalone or Parts Included
Depending on your current situation, you can choose between a standalone product or one with parts included. If youโre building an AR-15 pistol from scratch and have parts, like a buffer and the buffer spring, a standalone buffer tube is what youโll want. However, if you want the whole kit and kaboodle all at the same time, obviously a kit will do.

People Also Ask
To help you with your search for the perfect AR-15 pistol buffer tube, weโve decided to add a couple of frequently asked questions. These were asked by people who want to know more information about the legality of these parts as well as the difference between a carbine and pistol gas system. Here are the following questions:
Is it Legal to Attach a Rifle-Length Buffer Tube to an AR Pistol?
As far as we know, the ATF has not stated that a rifle-length buffer tube is illegal to attach to an AR pistol. However, the debate on the legality is up in the air. Itโs important to do your own research to determine whether or not it is legal to do so in your jurisdiction. Itโs good to err on the side of caution so you donโt face any potential legal headaches. Alternatively, when in doubt, donโt.
What is the Difference Between a Carbine and Pistol Buffer System?
One of the distinct differences between a carbine and pistol buffer system is length. A pistol-length system is shorter in length and more reliable compared to the carbine buffer system. However, some say the tubes themselves are pretty much the same exact length. Another thing that some AR-15 owners say is that one of them has less spring noise than the other.
