About

What it is, and why it matters

Copy a link to this section

The Charleville Model 1766 is a .69 caliber flintlock smoothbore muzzle-loading musket, a lightened refinement of the heavier Modèle 1763 and the standard infantry arm of the French Army in the years before the definitive Modèle 1777. The 1766 pattern thinned the barrel wall, shortened the lock, slimmed the walnut stock and replaced the earlier trumpet-shaped ramrod with a lighter button-head rod retained by a spring under the breech. Shipped in large quantities to the American Continental Army during the Revolutionary War, it served as one of the principal patterns the first U.S. military muskets were copied from.

Muskets of the 1766 light pattern were among the French arms that France shipped to Washington's Continental Army, and they directly informed the design of the United States Springfield Model 1795.

Often grouped with the Modèle 1763 as the '1763/1766 light pattern'. Weight figure follows George Moller's research (~8.36 lb); modern reproductions are typically heavier at around 10 lb. Barrel and weight vary slightly across the Charleville, Saint-Étienne and Maubeuge arsenals.
