What is the missing step in the function check for the M240?

Placing the safety on "S" safe is a crucial step in ensuring the safe handling of the M240. It is designed to prevent any accidental discharge of the weapon while it is being checked or handled. By engaging the safety to the "S" position, the user can confidently conduct other checks, such as verifying the ammunition and inspecting the weapon, without the risk of firing.

Safety protocols are paramount in firearms training and operation, emphasizing that the safest approach involves ensuring that the weapon is rendered inoperative before any further actions. This is particularly important in a military or operational environment, where the M240 may be handled by multiple individuals or in various conditions. By adopting this safe practice, operators ensure not only their safety but also the safety of those around them, reinforcing a culture of caution and responsibility in handling firearms.
