I have several AR15's that range from pre-ban to post ban, carbine to H-Bar configuration. All are different makers AND have different market values and were purchased at random over a long period of time. Reading a great many posts here and elsewhere I find that in performance and quality one AR is pretty much the same as another, so much so that in a serious situation I could very easily choose the least expensive/quality AR rather than the "best". This of course seems to conflict with the majority of posts that would relate that brand X is a "super gun", heads and shoulders above the rest and therefore worth hundreds of more dollars!. Are their others out their who have owned several different brands of AR15's who have come to the same conclusion? Competition AR's don't apply, at least I don't think they do.
