The Lebel Model 1886 rifle (French: Fusil Modèle 1886 dit "Fusil Lebel") is also known as the "Fusil Mle 1886 M93", after a bolt modification was added in 1893. It is an 8 mm bolt action infantry rifle that entered service in the French Army in 1887. It is a repeating rifle that can hold eight rounds in its forestock tube magazine, one round in the transporter plus one round in the chamber. The Lebel rifle has the distinction of being the first military firearm to use smokeless powder ammunition. The new gunpowder, "Poudre B," was nitrocellulose-based and had been invented in 1884 by French chemist Paul Vieille. Lieutenant Colonel Nicolas Lebel contributed a flat nosed 8 mm full metal jacket bullet ("Balle M," or "Balle Lebel"). Twelve years later, in 1898, a solid brass pointed (spitzer) and boat-tail bullet called "Balle D" was retained for all 8mm Lebel ammunition. Each case was protected against accidental percussion inside the tube magazine by a primer cover and by a circular groove around the primer cup which caught the tip of the following pointed bullet. Featuring an oversized bolt with front locking lugs and a massive receiver, the Lebel rifle was a durable design capable of long range performance. In spite of early obsolete features, such as its tube magazine and the shape of 8mm Lebel rimmed ammunition, the Lebel rifle remained the basic weapon of French line infantry during World War I (1914–1918). Altogether, 3.45 million Lebel rifles were produced by the three French state factories between 1887 and 1916.[1]

The Mle 1886 Lebel rifle was issued with a long needle-like quadrangular épée bayonet, the Épée-Baïonnette Modèle 1886, with a length of 52 cm. (20 in.). With its X-shaped cross section, the épée bayonet was optimized for thrusting, designed to readily penetrate thick clothing and leather. The bayonet was dubbed "Rosalie" by French soldiers who were issued it during World War I.[1]
