LBE Unlimited AR15 Buffer Tube Kit

Yes, this is a complete assembly. It includes the six-position buffer tube, recoil spring, buffer, receiver end plate, and castle nut, so you have all the necessary hardware to complete your lower receiver build.

Yes, this is a Mil-Spec buffer tube, meaning it is designed to fit standard Mil-Spec stocks. If you are using a commercial-spec stock, it will not fit properly on this tube.

The woodland brown finish is a distinct, earthy tone designed to add a custom aesthetic to your build. It is a durable coating, but keep in mind that color matching can vary slightly depending on the lighting and the other components in your setup.

You will need a castle nut wrench (often called an AR-15 stock wrench) to properly tighten the castle nut and secure the end plate. While some people attempt this with other tools, a dedicated wrench is the safest way to avoid marring the finish.

Yes, the included buffer is a standard weight designed for reliable cycling in most typical AR-15 carbine configurations. If you are building a specialized setup, such as a short-barreled rifle or one with a suppressor, you may eventually need to experiment with different buffer weights.
