if you are not factoring in looks(how pretty of how ugly either one is), which platform, ar or ak, do you prefer in a 223/5.56/7.62x39 caliber rifle, and why? it is my understanding that ak's are a lot more tolerant to being bathed in mud/dirt etc & still able to perform well(and I think the ak has been around much longer). I have also been told with an ar you should only use brass cased ammo and not steel cased as it is too hard on the bcg, etc, whereas the ak will eat almost anything you feed it. the same people also say that you can shoot an ak until the barrel is red hot, dip it in cold water, and keep shooting it but that you wouldn't be able to do that with an ar. Sorry if this is too much in one post, but please share your thoughts with me on this.
