The MKA 1919 stock adapter assembly is designed for the Akdal MKA shotgun upgrade. All bolts are included in the assembly. However, the stock, castle nut, and buffer tube will need to be purchased separately in order to complete the upgrade to the collapsible stock.
How we make the adaptor.
The stock adaptor for your MKA 1919 Shotgun stock 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 https://www.russprodco.com/. 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 do not need the buffer tube adaptor, you may purchase the stock adaptor alone on our product page: https://ar-shotgun.com/product/mka-1919-stock-adapter/.
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.
