I would still rather have an AK47, it's less accurate then the US M16, but it's just plain un stopable.

I've seen some guy have it so hot that the wooden grips are on fire and it still won't stop shooting. I've seen people bury them in sand, mud, dunk them in water, even bend the barrels around. but nothing you do will stop it from working for you.
