That is why I stick to the 5.56mm and assault clips. Way more powerful.
You should upgrade the lethality with a flash suppressor and pistol grip too. Almost no force short of a super volcano could stop you with that kind of power in your hands.
I have also found that the black or camo AR’s are even more powerful. I’ll bet if it had a bayonet lug on it you could drop a blue whale from 100 miles away.
