Like waves, news stories tend to come in threes. In this case, we present the third celebrity gun for sale. Saying that, this M-16A1 (equipped with an M-203 grenade launcher) may already be sold; RM Auctions is putting the fully-functional Scarface machine gun on the block even as I type. It’s expected to fetch $150,000-plus. And why not? This is the little friend that Al Pacino’s character asks his antagonists to greet.
