Now that the crime bill is gone there are a huge number and variety of AR-15 pistol posts on the forums. AR15.com has always been the ultimate resource and now there is a huge number of people playing with a system that was never really tested all that much in the past...
I think that an AR-15 pistol forum would add to the boards, provide a resource and common area for people to trouble shoot these weapons, and combine all of these related topics that are now getting posted all over the place to a single location....
I tried to gauge interest and you can see the results here:
