I have owned both. I now have Norinco MAK-90 and have fired many rounds without a single jam. Not as accurate as the AR but good enough. I owned a Colt AR about seven years ago but had to sell it when I first got married because we needed the money. It was very accurate and very well made. It would function without any jams on "namebrand" ammo but when I shot Wolf or other offbrand ammo it ceased being a semi-automatic and became a jamo-matic. I always had this in the back of my mind about the rifle and it bothered me. I will own another AR someday so I will be cool in the eyes of the gunsnobs at the range but I will defend my son,my wife, and myself with the AK.
