If your budget allows for $1,300 or so, I'd say get the Sig 556 that starts shipping this week. If it lives up to expectations, you'll have the best of both the AR (accuracy, common / cheap mags & ammo, drop down magwell, good ergonomics, optic rail, good sights once you buy the BUIS of your choice, etc.) & AK (it should run and run and run).
Not to offend .308 Galil types, but to get one is gonna cost you like $2500 or so. Not many imported, not many for sale, not cheap. Personally having fired them I prefer the FAL.
