The US Springfield Model 1842 Musket was a .69 caliber percussion lock musket manufactured and used in the United States during the 19th Century. It is a continuation of the Model 1816 line of muskets but is generally referred to as its own model number rather than just a variant of the Model 1816. It was the most common weapon used in the Mexican-American War and the first year of the American Civil War. Standard musket had an overall length of 58 inches and barrel length of 42 inches. A shorter musketoon version M1847 also existed. M1842/1847 were the last smoothbore muskets of the US Army, being replaced with Springfield M1855/1861 .58 caliber rifled muskets.
