Apologies if this has been posted before. This is a short video about the Girandoni air rifle that Lewis and Clark took with them as they traversed the country. It's a pretty cool video that I think many people here would enjoy. The NRA believes that it could be the most important rifle in US history.

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.
