AR-15 Pistol Buffer Tubes
We offer two different types of pistol buffer tubes for your AR-15 pistol build. Both are extremely durable and it really comes down to personal preference. We also offer a crenellated butt cap that will fit either model and foam covers.

AR-15 Pistol buffer tube w/o gusset, Model PB01
This AR-15 pistol buffer tube is a simple, robust solution to equipping your AR-15 pistol economically without sacrificing quality. It is CNC machined from aircraft quality aluminum, hard coat black anodized and designed for use with any standard end plate.

Some buffer tubes on the market require that you modify the lower receiver by tapping the detent spring hole and inserting a small, socket set screw to retain the spring. In addition to that, those buffer tubes will not allow you to use an end plate of any type so your sling attach points are very limited. A final drawback is that they leave the end of your lower receiver exposed and since it is aluminum, it is much more likely to take damage than a steel end plate would.

With our buffer tube you simply choose the end plate you want to use and assemble it like you would any other lower. This allows you to keep your original end plate or replace it with one that has single or ambidextrous type sling attachment loops like the one shown in the pictures below.
