The Mondrago'n rifle (Ger.)
The Mondragon rifle was invented by Manuel Mondragon, a Mexican army officer, in 1887 and built by SIG in Switzerland. It was the first semiautomatic battle rifle ever fielded. It was issued as the Modelo 1890. It probably would have been totally unknown except the Mexican government defaulted on the payment and forfeited the undelivered rifles, which SIG sold to the Imperial German army during the unpleasantries in Europe from 1914-1918.
