The series of previews kicks off this week with a look at "The Air Rifle that Won the West." You read that right. While the Winchester Model 1876 and it's role in America's westward expansion has led to that iconic lever-action rifle being known as THE gun that won the West, NRA Museums Director Jim Supica highlights another candidate for the title. The little known Girandoni Air Rifle predates the Model 1876 and played a small but important role in opening America.
