The Model 1968 was deployed during the Falklands (Malvinas) campaign to retake Port Stanley and the weapon was used during Mount Longdon. The Argentine Army units which being the 7th Infantry Regiment and Argentine Marine platoons in the outer hills defending those positions used the Model 1968 as a direct-fire and indirect-fire anti-tank piece against advancing British formations. One contemporary account states these rifles were used to bombard advancing 3 PARA units and even hit a British MILAN anti-tank position during the Battle of Mount Longdon. The Argentine military attempted to use it as self-propelled artillery or as a tank destroyer. At least two prototypes (one being either an IHC M5 or M9 half-track and the other a Bren carrier) were fitted with a six-cannon mount each, similar to that of the US-made M50 Ontos.
