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).  Blasted and black Type III hardcoat anodized.

1913 rail with QD mount now included!

Note: This part does not use M-LOK attachment, it has two 10-24 threaded holes that match 3-slot rail bolt spacing and thread pitch for increased strength.
