The British .577 Snider–Enfield was a breech-loading rifle. The American inventor, Jacob Snider created this firearm action, and the Snider–Enfield was one of the most widely used of the Snider varieties. The British Army adopted it in 1866 as a conversion system for its ubiquitous Pattern 1853 Enfield muzzle-loading rifles, and used it until 1880 when the Martini–Henry rifle began to supersede it. The British Indian Army used the Snider–Enfield until the end of the nineteenth century.
