Looking to build a sort of long boy honey badger.

I have a complete AR with a geissele buffer/ tube and H2 spring. https://www.freedomtrading.com/Q-Shorty-Stock-BLK-p/acc-shorty-stock-black.htm This stock has peaked my interest. The H2 buffer and spring are great, no raddle. Is there a longer tube version of this out there so I can keep using my current spring ad buffer?
