Anyone know where I can find a list of all of the AR-15 components that can be purchased seperately, and which if any components have to be purchased as part of a kit? I think I saw a post awhile back that had a link to a forum that caters to AR15 aficionados, but can't seem to find it by doing a search. I am going to build an AR-15 for varmint hunting, but am going to try to keep costs as low as humanly possible without resorting to buying garbage components. I am not in a hurry, so my thoughts are if I can get a parts list I can tape it next to my PC and whenever I see a really fantastic sale price on a part I can buy it and cross it off the list. This way I can buy the gun in small pieces to help not only keep the price down but spread out the purchase over a period of time that will keep my wife talking to me.
