I may be wrong but the typical weaponry didn't change much at all during the 18th century. There was only minor difference between the British Brown Bess and the French standard musket, and only minor detail changes to each. Sure some American units used rifles, but they were a minority. Kings Mountain was the exception to that rule. Also with the exception of the frontier, smoothbore muskets, or fowling pieces were the normal household long arm among the civilian population.
