http://palmettostatearmory.com/2066.php Federal Lake City XM855LC AC1 5.56mm 62gr. FMJ Ball Ammo 420rds on strippers for $129 with $10 shipping.
Not bad, especially shipping to South Korea.....
Not trying to steer you away from it. But if its for range use, might look towards XM193. It might be a little cheaper too. Or if your not worried about the steel cases, look to our Russian friends for ammo.
BTW what upper did you end up with?
