At the 240 sustained rate, how often should the barrel be changed?

• A. Every 10 minutes
• B. Every 2 minutes
• C. Every 1 minute
• D. Every 15 minutes

Answer: (A)

During sustained fire, the barrel heats up quickly and needs a practical cooldown period to avoid overheating and excessive wear. At a sustained 240 rounds per minute, the established practice is to swap the barrel every ten minutes. This interval keeps temperatures within safe operating limits, preserving accuracy and reliability while still allowing continuous fire for a useful period before changing. Changing more often, like every couple of minutes or every minute, would be unnecessarily frequent and slow you down, while waiting longer than ten minutes would let the barrel overheat and degrade performance or damage components. A ten-minute change balances heat management with operational tempo.
