Fusil FX-05 Xiuhcoatl (Fire Snake) Assault Rifle (2008)

Authored By Staff Writer | Last Updated: 5/22/2015

The FX-05 Assault Rifle was first observed in 2006 and entered formal service with the Mexican Army in 2008.

Seeking to upgrade their supplies of standard-issue HK G3A3 series assault rifles, Mexican authorities centered in on the HK G36 system. The original G3 appeared in 1959 and went on to see widespread use with a host of countries and in countless conflicts. The system relied on the 7.62x51mm NATO cartridge and fired through a roller-delayed blowback action from a 20-round detachable box magazine. A 50-round drum could be affixed for the squad automatic weapon role. The G36, on the other hand, represented a much more modern solution from the same German Heckler & Koch firm. It was introduced in 1997, fired the 5.56x45mm NATO cartridge from a gas-operated/rotating bolt action and was compatible with a 30-round box magazine or 100-round "C-Mag" drum. The Mexican government and Heckler & Koch had agreed to a locally-produced version of the G36 in which factories would be built directly in Mexico under license.

At some point, it was determined by Mexican authorities that it would make more fiscal sense in the long run to design, develop and produce an indigenous assault rifle system. As such, the HK G36 initiative fell to naught and work began on developing a suitable modern replacement for the outgoing HK G3 models. The result became the FX-05 which is entirely constructed from local resources. it represents a drastic departure for the Mexican military and security forces who had relied on importation of foreign weaponry for decades before the arrival of the indigenous FX-05. The FX-05 subsequently entered service in 2008 and has seen considerable action in the Mexican drug wars to date. Manufacture of the FX-05 is handled by the Direccion General de Industria Militar del Ejercito (DCIME).
