An AR-15 pistol buffer tube, also known as a receiver extension tube, is a specific type of buffer tube designed for use with AR-15 pistols. It serves a critical function in AR-15 pistol builds, and there are some key differences between it and a standard rifle buffer tube. Here's what you need to know:

Attachment Point: The AR-15 pistol buffer tube is threaded and attaches to the rear of the lower receiver, just like a rifle buffer tube.

Length: The pistol buffer tube is shorter in length compared to a rifle buffer tube. It's designed to accommodate AR-15 pistols, which have shorter barrels and no traditional shoulder stock. The shorter length allows the shooter to use a pistol brace or stabilizing arm brace instead of a shoulder stock.

Pistol Braces: AR-15 pistols often use stabilizing pistol braces. These braces can be attached to the pistol buffer tube and are designed to provide additional support and control while firing the pistol. It's important to note that these braces are not intended to be shouldered like a traditional stock in most cases due to legal and regulatory considerations.

End Plate and Castle Nut: Similar to a rifle buffer tube, the pistol buffer tube typically includes an end plate and a castle nut. These components are used to secure the buffer tube to the lower receiver and to lock the pistol brace in place.

Compatibility: When selecting an AR-15 pistol buffer tube, it's important to ensure compatibility with your specific AR-15 pistol build. Some AR-15 pistol buffer tubes are designed to work with certain brace designs.
