What command is automatically executed by a Cadet before he hands his rifle to an inspector?

Inspection, Arms

Explanation:

With the Inspection Arms command, the Cadet raises the weapon at the port position for inspection

The command Ready, Port, Arms has to be given next to Inspection  Arms before further movement can be commanded

Cadets are not advised to practice Inspection Arms except where a demilitarized rifle is available

Drill commands or Drill ceremony are commands for a group of marching Cadets in a foot drill.

good question. i'll be looking into that. (this is a joke sir)
