U.S. Hall Model 1819 Breechloading Flintlock Rifle






The Hall Model 1819 Breechloading Rifle marks two important firsts in firearms history. This model was the first breechloading rifle to be adopted by the United States as a regulation military arm. It was also the first to successfully employ the concept of identical, precision-made, fully-interchangeable parts. Rifles and carbines in various models and calibers were produced from 1824 until 1853.
