There are none that I can think of off the top of my head, but that doesn't mean it hasn't happened. Again, I think criminals will use anything in the commission of an offence that would replicate.... I think about robberies that happen sometimes with simply a barrel of a gun, not a complete firearm, maybe wrapped in a blanket so that the store owner doesn't know what they're facing.
