So in my re-evaluating my firearm needs, I have a gap in the inventory for a long range gun. Now I'm not what I would call a long range shooter nor do I really care to get down to brass tack...drivers (tee hee). I want .308 due to poplularity and use with military (ie plenty of ammo available). I'm looking into a M1A or FAL, but after palying some COD:MW2 with AresV and asking what he thought of the M1A, he suggested a AR in .308, since it's same operation as a 5.56 AR nothing new to learn. I hadn't even given them a thought, but it does sound like it will fit my needs better. What are the negatives and positives of the .308 AR as I know next to nothing about them?
