The Charleville Musket was one of the most advanced rifles of its day during the 1770-1776 time period. There were smooth bore and rifled bore versions, hardened retaining bands for the barrel, the scouring stick was modified with a pear shaped head for better cleaning and powder compression. The scouring stick had a compression spring. Finally it had a modified lock plate, just to name just a few of the changes during that span of years.
