Yeah, the gun forum is generally referred to as the "Gungeon." The main function of that and the Israel-Palestine (aka "IP") forum and a couple of others is to keep the non-mainstream or otherwise-embarrassing members off the big forums with their issues, and thus avoid the divisive flame wars that inevitably result when they get out of their cages.
Over time the Gungeon has been about evenly divided between those who support the RKBA, and those who want every weapon down to and including sharpened pencils banned.
