I'm in search of an upper and wanting to look around on other boards that are geared towards ARs. I'm a member at many places, but I want the forum to be mainly channeled towards AR users. I know of AR15.com and M4Carbine forums. Anything I'm missing? I've been looking for a couple of days, but I can't find a 18" barrled complete upper w/ BCG and 13"(approx) full rail. I've found ONE that I like, but it's a damned Stoner and is $2400. I think I'm looking to spend around $1,100-$1,300 in case any of y'all know any leads. So -- any forums I'm not aware of?
