I'm trying to get some solid advice. Would like to hear any opinions on what is better for a guy wanting investment/part time range shooting/home protection. I thought I was ready to get a Colt 6920, but have had some friends tell me that the AK is "more reliable", and may be better suited for my purposes. I very much value what I hear from the guys on the forum here, authorities on the subject of AR's. Many thanks.
