Which step comes immediately before firing in the 240B/M2 cycle?

Explanation:
Locking is the step that must happen right before firing. After a round is fed and chambered, the bolt locks into the chamber to form a secure breach so the high-pressure gases can act on the bolt without the breech coming open. Once the bolt is locked, the firing sequence can occur, and the round is ignited. After firing, the bolt unlocks, extracts, and ejects, then the cycle returns to feeding for the next round. Feeding and chambering occur earlier, and unlocking happens after firing, so locking precedes the shot.
