The US Springfield Model 1795 Musket was the first smoothbore flintlock musket produced in the United States. It was based on the French Model 1763 Charleville musket and like the French design was a .69 caliber musket. The Charleville and the Brown Bess were the two most famous muskets during the 18th century. The Charleville musket had been the primary musket used by Americans during the American Revolutionary War. The Charleville being the more accurate of the two, it was selected as the model for a new American musket.
