Springfield model 1873

The Springfield Model 1873 was a trapdoor breechblock service rifle produced by the Springfield Armory for the United States military. It was the first standard-issue breech-loading rifle adopted by the United States Army (although the Springfield Model 1866 had seen limited issue to troops along the Bozeman Trail in 1867). The rifle, in both full-length and carbine versions, was widely used in subsequent battles against Native Americans and was also issued in limited numbers to volunteer units in the Spanish-American War and the Philippine Insurrection. The Model 1873 was the fifth variation of the Erskine S. Allin trapdoor breechblock design. The infantry rifle model featured a 325⁄8-inch (829 mm) barrel, while the cavalry carbine used a 22-inch (560 mm) barrel. It was superseded by an improved model, the Springfield Model 1884, also in .45-70 caliber.
