Which limitation was partially overcome by the Song Dynasty's use of cast composite crossbow triggers?

💡 Explanation

Cast triggers allowed for relatively consistent parts via investment casting, easing production quantities, because they simplified manufacturing relative to individually hand-fabricated mechanisms; therefore, feasibility increased, rather than trigger hardness changing or synchronization concerns being central.
