naw, say it aint so. EVERYONE "knows" that AR-15's don't last more than a VERY few thousand rds, malfunction with every shot, etc. Funny, all the yotes and feral dogs that I have hit with 60 gr Nosler Partition softpoints have had real problems doing what ALL the guys shot with 223 ball in wars seem able to do (ie, carry on as if bitten by a mosquito). In fact, all of them were knocked for a loop and couldn't get up again. Strange, since the 223 is so "feeble", right?
