During the command MAKE READY, what is checked for proper alignment and serviceability?

During the command "MAKE READY," the sights are checked for proper alignment and serviceability because they are essential for accurate aiming and ensuring the rifle is functioning optimally. Properly aligned sights allow the shooter to make precise adjustments to hit the target accurately. The shooter must confirm that the sights are properly set according to their individual preferences, as well as ensure they are clean and free of any obstruction that could impair visibility. This step is critical before proceeding with any firing sequence, as the sights are the primary means by which a shooter aligns their line of sight with the target.

While other components, such as the magazine, trigger guard, and ejection port cover, play important roles in the overall operation and safety of the rifle, they do not specifically pertain to aiming alignment. Checking the magazine ensures it is loaded and seated correctly, the trigger guard maintains safety during handling, and the ejection port cover protects against debris, but none of these components directly affect the alignment of the sighting system. Therefore, the emphasis on the sights during this command is foundational for effective marksmanship.
