Ah yes, the mighty, mystical AK. Gift from the God of War.
Not only does it never need maintenance,
never fail to fire due to water, sand, or being run over by a Humvee,
can eat up even low priced steel cased ammo like it was candy,
and is never a worry about messing up it's appearance with scratches and dings because it's already so damn ugly.
It can also be used as a club to beat your opponents to death with.
