A gunsel is a slang term used to describe a criminal carrying a gun. On September 3, 1885, Buford "Mad Dog" Tannen shot at Marty McFly in the Palace Saloon. Buford Tannen then attempted to hang Marty, but he was saved when Doc Brown used his homemade sniper rifle to shoot the rope that was around his neck. On September 7, 1855, Buford Tannen shot Marty McFly, who was going by the name "Clint Eastwood". However, Marty survived as he used a trick he learned watching A Fistful of Dollars to create a makeshift bulletproof vest.
