RSC Fusil Semi-Automatique Mle1917
Ribeyrolles, Sutter, and Chauchat - made by the Manufacture d’Armes de Tulle in France c.1917~18.
8x51mmR Lebel five-round en-bloc clip, gas-operated semi-automatic, loaded from the bottom.
Made with several Lebel parts, the RSC Mle1917 was the first semi-automatic military rifle to be mass-issued and used during a major conflict, namely World War one. It was a far cry from the revolutionary designs of the French rifle trials of the early 20th century, but it was decently reliable and provided a lot more firepower than the old Lebel Mle1886.
