The only thing that really bothers me is that there are basically two ACRs. One is by Bushmaster and the other is by Remington. The Remington ACR actually has a 1x7 barrel twist I believe and is chrome-lined, while the Bushmaster is not. This is probably indicative of other differences between the two. I'm afraid the Bushmaster version is more of a civilian toy or novelty item than an ultra-reliable my-life-is-on-the-line weapon. I don't want that to be the case, but time will tell.
