thehighroad.com has always been a top gun board. So is ar15.com.
Was on TheHighRoad.org for a long time, through the...um...”late unpleasantness”. It took a turn for the worse (relatively), but maybe it has come around. Who is running it now?
AR15.com is good if you focus on gun-related stuff only. My only problem with it is they let the liberaltarians bashed Christians and Christianity ad nauseam in their General Discussion forum, but say one negative thing about Islam and you get your pee pee slapped.
