What occurs after the barrel is stopped in a recoil operated weapon?

In recoil operated weapons, when the barrel is stopped after firing, the next steps are critical to the functioning of the firearm. Immediately following the stoppage of the barrel, the energy generated from the initial shot causes the bolt to move backward. As the bolt travels back, it compresses the recoil spring. This compression of the spring stores potential energy that is crucial for chambering the next round.

As the bolt moves back, it also ejects the spent cartridge case, making room for a new round to be chambered when the spring decompresses and pushes the bolt back forward. This entire sequence ensures that the weapon can prepare for quick follow-up shots.

This process is essential in maintaining the weapon's rate of fire and efficiency. The action of compressing the spring and chambering a new round is pivotal, and thus, this option accurately describes what happens in the operation cycle of a recoil operated weapon after the barrel is stopped.
