"Mauser Bolt Action Rifle" (Mauser Bolt Action Rifle) is a series of manual rifles developed by German firearms designer Peter Paul Mauser (Peter Paul Mauser) and his family business (Mauser Company, Mauser-Werke). With "rotating rear pull bolt" (Bolt Action) as the core design, it is one of the most influential rifles from the 19th to the 20th century. Its history spans two world wars, and technological innovation and military applications have profoundly affected the development of global firearms.

It is a bolt action rifle widely used by the French military from the late 19th century to the early 20th century. It was first adopted by the French army on March 14, 1890, and a full-length rifle variant was introduced in 1902. During World War I, the B é tier rifle was not only used by the French army, but also equipped the French Foreign Legion and French colonial forces. In 1916, in order to improve combat effectiveness, the B é tier system underwent significant improvements and the "Modify é 1916" version was launched. The main improvements included adding a handguard and expanding the magazine capacity from 3 to 5 rounds to match the capacity of the Mauser rifle used in Germany.
