Manufacture d'armes de Saint-Étienne (lit. St. Étienne Arms Manufacturer) was a French state-owned firearms manufacturing company. Founded in 1764, the site was annexed in 2001 and the company merged into the Nexter defense conglomerate.


The company was founded in 1764 with the approval of King Louis XV of France and overseen by a Mr. de Montbéliard. A more modern factory was built in 1864, with rifles like the Gras and Chassepot being produced around that time.

The company experienced a decline around the 1960s, with the site being taken over by GIAT Industries in 1989; the site was closed in 2001 and was gazetted a monument historique in 2006.[1]
