The CAL (Carabine Automatique Légère, Light Automatic Carbine) is a Belgian assault rifle that was manufactured by Fabrique Nationale.
It resembled the company's highly successful FN FAL, but was an original design.
Unlike the FAL, it was a market failure, although its development led to the more successful FN FNC.
Prior to the development of the CAL, FN had already constructed a scaled-down FAL prototype before shelving the idea as unmarketable.
While the construction of the new CAL reflected these design principles, it was still relatively expensive and complex, and met with no significant sales.
