The Fusil Modèle 1874 or Gras was the French Army's primary service rifle from 1874 to 1886. Designed by Colonel Basile Gras, the Gras was a metallic cartridge adaptation of the single-shot, breech-loading, black powder Chassepot rifle. It was developed from 1872 to 1874 as a response to the German adoption of the Mauser Model 1871 metallic cartridge rifle.

Modified in 1880 as the M80 with an improved breechblock and in 1914 as the M14 to accommodate the 8×50mmR Lebel smokeless powder cartridge, the Gras was replaced as the standard-issue service rifle by the Lebel in 1886.

Converted from the Chassepot, the Gras^[2] was in 11 mm (0.43 in) caliber and used black powder centerfire metallic cartridges with a 385 gr (24.9 g; 0.88 oz) bullet over a 78 gr (5.1 g; 0.18 oz) charge. It was a robust and hard-hitting single-shot weapon. Additionally it had a triangular-shaped Model 1874 "Gras" sword bayonet. The Gras rifle was replaced from 1886 by the Lebel rifle.

The Gras was manufactured in response to the development of the Boxer cartridge in 1866, and the British 1870 Martini–Henry rifle which used it.^[3] Those were soon emulated by the Germans with the 1871 Mauser.^[3] The French Army set up a study group in September 1872 that chose the metallic over the paper cartridge. A second study group in 1873 looked at various metallic cartridge adaptations. Colonel Gras proposed a modification of the Chassepot to accept metal cartridges and on 7 July 1874, the French Army chose his design over the M1871 Beaumont rifle.

The Hellenic Army adopted the Gras in 1877, and it was used in all conflicts until the Second World War. It became the favourite weapon of Greek guerrilla fighters,^[4] from the various revolts against the Ottoman Empire to the resistance against the Axis, acquiring legendary status. The name entered the Greek language, and grades (γκράδες) was a term colloquially applied to all rifles during the first half of the 20th century. It was manufactured by Manufacture d'armes de Saint-Étienne, one of several government-owned arms factories in France. However most of the Gras rifles (60,000) used by the Hellenic military were manufactured under licence by Steyr in Austria.

The Gras rifle was partly the inspiration for the development of the Japanese Murata rifle, Japan's first locally-made service rifle.^{[citation needed]}

According to the Vietnamese historian Phạm Văn Sơn, a Vietnamese general in the Cần Vương movement, Cao Văn Thắng, managed to copy the design of "an 1874 type fast-firing rifle of French". However, the Vietnamese version did not have a rifled barrel, and the range was limited.^[5]

In 1915, 450,000 Gras rifles were sent to the Russian Empire.

After 1918, Mle 1874 rifles were exported to Yugoslavia, Poland and Greece.^[6]
