Which outcome accelerated the spread of cast-iron crossbows?

💡 Explanation

The casting process enabled standardized parts like triggers, using ASSEMBLY LINE production, because replication became easier than craft production; therefore, weapon production expanded rapidly, rather than remaining limited by complex hand-fitting by individual artisans.
