What does the fifth prefire safety check verify?

The fifth prefire safety check is essential for ensuring that a weapon is ready for safe operation. This specific check verifies the firing selector position, confirming that the weapon is set correctly for the intended mode of fire—either safe, semi-automatic, or fully automatic. This step is crucial because it directly impacts the control a user has over the weapon and helps prevent accidental discharges, which can occur if the firing selector is not in the desired position.

Understanding the firing selector's significance underlines its role in maintaining operational safety and preparedness during firearm use. For example, having the firing selector in the safe position before handling or transporting the weapon provides an added layer of safety against unintentional firing. This underscores the importance of thoroughly conducting this check as part of the overall prefire safety procedures.
