What should you do after opening the action of an air rifle?

After opening the action of an air rifle, the appropriate next step is to charge the rifle with air. This step is essential because it prepares the rifle for firing by pressurizing the air system. Properly charging the rifle with air ensures that it is ready to operate correctly when the trigger is pulled. It is critical in the sequence of operations to ensure safety and functionality.

Opening the action allows for any existing round to be removed and ensures that the chamber is clear, which is a safety measure. Charging the rifle afterward signifies that the shooter's intention is to prepare for shooting after confirming the rifle is in a safe state.
