The design replaces the buffer tube, buffer spring, buffer and pressure plug. This allows use as a buffer tube plug for pistol builds, or attachment of accessories via a standard 3-slot 1913 rail section, such as MPX folding stocks or braces. The system can be adjusted to provide optimum pressure to the 22lr backplate for maximum reliability (replaces the pressure plug system in a buffer tube receiver).
1913 rail not included. Although any 3 slot rail intended for M-LOK use should work, but we use and recommend Magpul brand to ensure proper fitment:
Note: This part does not use M-LOK attachment, it has two 10-24 threaded holes that match 3-slot bolt spacing and thread pitch for increased strength.
