In my opinion it's kinda pointless debating the virtues of a rifle for combat on a forum more inclined towards civilian shooting activities. I guess the people to ask would be special forces units, why do they still use M4's when there are supposedly better options? I'm not all up to play with it, but didn't US special ops ditch the FN SCAR and go back to M4's/416's because they thought it didn't offer any advantage over what they already had? For me personally, I can't really think of any semi auto platform more suitable for civilian applications than AR's. If I could only own two centrefires it would be a nice bolt action and a good AR. As for the comment about pistols, mp5's etc...I don't have the energy to go there...
