The AR-15/HK416 carbine buffer tube, also known as the receiver extension tube, is a key component of the AR-15 and HK416 style rifles. It serves several important functions in the firearm's operation. Here are some key points:

Attachment Point: The buffer tube is threaded and attached to the rear of the lower receiver. It is the part of the rifle where the stock or buffer tube assembly attaches. The stock or brace can then be mounted onto the buffer tube.

Buffer and Spring Housing: The buffer tube houses the recoil buffer and action spring. The buffer and spring are essential for controlling the cycling of the firearm, mitigating recoil, and ensuring reliable functioning.

Adjustable Stocks: Many buffer tubes are designed to accept adjustable stocks or stabilizing braces. These stocks can be adjusted for length to fit the shooter's preference and body size.

Compatibility: It's important to choose a buffer tube that is compatible with your specific AR-15 or HK416 rifle. Different designs and lengths of buffer tubes are available, and you should select one that matches your rifle's configuration.

End Plate and Castle Nut: The 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 stock or brace in place.

Brace vs. Stock: Note that some firearms use stabilizing braces instead of traditional stocks, which are designed to help shooters more comfortably and safely handle the firearm. The choice of brace or stock may have legal and regulatory implications depending on your location.
