What does it mean to "ground" a rifle?

To "ground" a rifle means to safely place it on the ground in a way that ensures it cannot be accidentally discharged. This is typically done by opening the action of the rifle and inserting a cleared barrel indicator (CBI). The action must be open so that it is visibly safe, reducing the risk of misfires or accidental discharges. By using a CBI, the rifle is clearly marked as unloaded and safe, which is important for maintaining safety on the range.

Other options involve actions that do not prioritize safety in the same way. For example, placing a rifle in a case does not guarantee that it is clear of ammunition and safe for handling. Handing it to a range officer or laying it on the firing line without precautions could introduce risks in a live shooting environment. Hence, grounding a rifle, as defined, ensures the highest safety protocols are being followed.
