How we make the adaptor.

The stock adaptor for your Panzer Arms AR12 KMR Shotgun stock upgrade is made in the USA.  These parts are manufactured using a CNC mill.  We use 6061T6 aluminum is the material 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 would like to purchase the whole stock upgrade, you can purchase the kit 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 Folding stock adaptor in place and attach the stock.
