Notes

The FN CAL represents FN's initial entry into the 5.56mm market, predating its highly successful FNC by over a decade. The rifle's complexity and cost made it commercially unviable against simpler designs like the M16. The CAL's three-round burst mechanism was ahead of its time, as this feature would not become common on military rifles until the 1980s. The lessons learned from the CAL's market failure directly informed the design philosophy of the FN FNC, which prioritized manufacturing simplicity and cost-effectiveness. Some sources report 20- and 30-round magazine capacities, while MilitaryFactory also mentions 25-round options. The weapon was adopted in small numbers by Gabon, Lebanon, Mexico, and Morocco.

Background

The FN CAL is often called FN's 'first failure' in the assault rifle market, a stark contrast to the legendary success of the FN FAL. Yet without the CAL's expensive lessons in 5.56mm rifle design, the world might never have seen the FN FNC, the SCAR, or the other successful FN military rifles that followed. Every great success story needs a first draft.
