FROM WIKIPEDIA
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. 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.
