Product Info

The stock adaptor is specifically made to upgrade the Panzer AR12 Gen 4 Polymer Shotgun.  However, it may be adaptable to other makes or models.

How we make the adaptor.

The stock adaptor for your Panzer AR12 Gen 4 Polymer Shotgun upgrade is made in the USA.  These parts are manufactured using a CNC mill.   6061T6 aluminum is the material we use for both parts.  We machine it to tight tolerances and bead blast to a matte finish.  The product is then black anodized via Russel Products in Akron, Ohio  In order to install the stock, the adaptor needs the Buffer Tube Adaptor addition.   Therefore, allowing connection between the adaptor and the buffer tube.   If you need the buffer tube adaptor, you may purchase the stock adaptor assembly on our product page:

How to Install.

Your Shotgun will need to be cut one inch from the lower to install the adaptor.  The adaptor will fit right into the lower.  You will then want to screw the adaptor in place and attach the buffer tube adaptor.  Next, use the set screw to ensure the buffer tube adaptor will not move once installed, creating a snug fit.  Once both of the adaptors are screwed into place the buffer tube and stock are ready to be put on.

  1. I wish I could give a better review but it took a while for the package to ship out and arrive and when it did the package was missing the bolt that comes with the adapter, one of two parts in the package.
