The FX-05 Xiuhcoatl ("Fire Serpent", literally "Turquoise-Serpent" in Classical Nahuatl,) is a Mexican assault rifle, designed and built by the Dirección General de Industria Militar del Ejército (General Directorate of Military Industry of the Army) through the Fabricas Militares (Military Factory). The rifle was officially presented in the military parade on September 16, 2006, in the hands of the Special Forces Airmobile Group, GAFE (Grupo Aeromóvil de Fuerzas Especiales).

The design was coordinated by the Centro de Investigación Aplicada y Desarrollo Tecnológico de la Industria Militar or CIADTIM (Center of Applied Research and Technology Development Military Industry) and SEDENA and all of its parts are built in Mexico. According to the director of the DGIM, Otilio Ramírez Serrano, by July 2019 approximately 155,000 rifles have been produced.

The FX-05 is distributed among the Mexican Armed Forces, and the military industry is aiming to produce 30,000 per year.
