The French rifle that could be cleaned with just rags and motor oil

In short: In the grueling environments of the Algerian War and Indochina, the MAS-49 became a legend of reliability. It was a semi-automatic workhorse so robust that it could be maintained with nothing more than basic supplies, offering a level of durability that defied the era's technical demands.

The MAS-49 was the result of 'spiral development,' a design philosophy where small, iterative improvements were made to successive models rather than radical overhauls. It evolved from the MAS-38/39 and MAS-40 prototypes, eventually refining the MAS-44. Only 6,200 MAS-44 units were manufactured, mainly for French Navy Commandos stationed in Indochina; however, the French Army chose the MAS-49 as their primary service rifle in July 1949, substituting various old bolt-action models such as the K98k and Lee–Enfield.

Technologically, the MAS-49 utilized a direct impingement gas system first tested by the French in 1901. This design allowed gas to move the bolt carrier to open the action, while a rear-locking tilting bolt—similar to the Browning Automatic Rifle—ensured reliability. A key mechanical advantage was that the system did not deposit gas fouling on the bolt itself, a separate part. This, combined with a mechanism that could be disassembled for cleaning in just a few seconds, contributed to its reputation for enduring harsh service in Djibouti, French Guiana, and the Battle of Kolwezi.

The rifle's evolution culminated in the MAS-49/56 in 1957. This variant was shortened and lightened for airborne and mechanized troops and featured a new combination compensator/rifle grenade launcher for NATO-standard 22mm grenades. Despite its success, production was eventually curtailed when the United States provided France with hundreds of thousands of M1 rifles and carbines between 1951 and 1960. The MAS-49/56 remained the French service rifle until 1979, when it was finally succeeded by the FAMAS bullpup assault rifle.
