Out of curiosity, Thanis, what would prompt you to include the AK-47 in the same category as these other two rifles? The effective range alone would put the AR-10 and M1A in their own categories, in my opinion, and without a doubt the .308 and 7.62 NATO rounds both handle light materials better than the 7.62x39. Regarding the AR-10 and M1A, like HotGuns says, I can't think of anything in particular that it does better, or even comparably, than the AR-10. For the amount of money that you'd sink into an M1A-type weapon to make it as accurate as an AR-10 type weapon, you'd already have a nice AR and glass to go with it, and probably some goodies besides (mags, ammo, the usual).
That being said, my AR-10 project isn't even going to be in .308 or 7.62 NATO.
