 The Model LV ("Visor") is a marksman variant equipped with a fixed STANAG mount over the rear sight base; the optic generally used in this role is the British SUSAT sight in some units, the standard being a nationally produced 4 power ENOSA scope.A starlight scope was also available.Another model with a rotating drum rear sight used by the Infanteria de Marina was also called LV, leading to some confusion, even in training manual and logistics.
