This could be the most important historical gun in the history of the U.S. It was used by Lewis & Clark during their Corps of Discovery expedition from 1803-1806. The illusion of superior firepower this single air rifle created — opponents never knew if there was one air rifle or 38 air rifles — enabled the small band of explorers to safely travel from east to west and back again and claim an area greater than one-half of the landmass of North America for the U.S. The Lewis & Clark Air Rifle can be seen at the NRA National Firearms Museum in Fairfax, Virginia.
This rifle is a reproduction of the Girandoni Air Gun used on the Lewis & Clark Expedition.
