What are the three steps in the cycle of operation for the M240 after feeding the weapon?

The cycle of operation for the M240 after feeding the weapon involves chambering, locking, and firing.

Chambering is the process during which the round is moved from the feed tray into the chamber of the weapon, making it ready to be fired. Once the round is chambered, the action must then accomplish locking, which secures the bolt into the chamber with the cartridge. This is crucial as it ensures that the round is held in place under the high pressures produced during firing. Finally, firing occurs when the trigger is pulled, causing the firing mechanism to ignite the primer of the cartridge, resulting in the round being fired. This three-step sequence is essential for the reliable operation of the M240 and enables it to perform effectively in a variety of conditions.
