What is the last step in the cycle of operations?

The last step in the cycle of operations for the M16A3/M4A1 Service Rifle is cocking. This step is crucial because it prepares the weapon for the next shot by resetting the hammer after it has fired. Once the firing pin has struck the primer, the cartridge is discharged, and the cycle continues through ejection, extraction, chambering, and feeding. However, until the weapon is cocked, it cannot be fired again. Cocking ensures that the rifle is ready to be fired again by resetting the firing mechanism, making it the final step in the operational cycle.
