, sure if we are talking a broad side of a barn.
I take it you've never shot an AK, they're known for reliability, definitely not accuracy. And WC is pretty spot on with his assessment on a standard AR-15's range with your typical 55 grain Walmart .223, no if you start getting into the 20-24" AR's with a 1/7th twist in the barrel to stabilize a much heavier grain load, sure, they can reach past 400 yards, but a .223 round doesn't have much behind it at that point. If I'm going past 300 yards, I'm pulling out my .308.
