Design Details
The design of the weapon includes telescopic, red-dot and mechanical sights; cold-forged barrel; folding and adjustable butt stock; as well as the capability to semi-automatic, three round burst and full auto fire. The weapon can be chambered for the 5.56x45mm NATO or the 6.8x43mm SPC round. It has a cyclic rate of fire of 750 rounds per minute. Most of the rifle's receiver is constructed of a polymer reinforced with carbon-fibers with an underlying titanium frame and comes in black, dark-green and desert-tan colors as well as the SEDENA digital camouflage patterns used by the Mexican army. The charging handle can be installed on either side of the rifle with gas piston located above the barrel, which operates under a multi-lugged rotary barrel system. Safety/fire mode selectors are located above the pistol grip on both sides of the FX-05.
The internal mechanism and barrel are made of advanced corrosion-resistant stainless steel. An Indigenous programmable air-burst grenade launcher is currently under development for the FX-05, which will be able to fire standard NATO munitions in addition to Mexico's new RSE-7 fuel-air grenade round but until it is finalized the FX-05 will use the AG36 grenade launcher as used on the G36. The FX-05 is one of the world's few assault rifles featuring polygonal rifling, which eliminates the normal grooves of a weapons barrel replacing them with a system of "hills and valleys" in a rounded polygonal pattern.
The FX-05 is available in several configurations optimized for differing use, including; Assault rifle, Carbine, Light machine gun and Sharpshooter variants.
