The 1795 Springfield infantry musket was the first US Military musket produced domestically. The design was a copy of the 1766 French musket that was used in large numbers by the US.
This .69 caliber flintlock musket was 60 inches long in total and weighed 10 pounds. Typical range of the musket was only 50 yards.
This musket was the basic issued weapon the War of 1812, Mexican-America War and even up to the Civil War. During the Civil War many were finally converted to percussion cap muskets.
Some members of the Corps of Discovery used the musket as well, making them a extremely well traveled musket from the start!
