This is Atlas Copco part number 3121016500 pressure spring, stocked at Crowder Supply as AC-3121016500. Springs in a pusher leg fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It is called out in the parts diagram for the BBC 16W WS Pusher Leg Drill. It comes off the Atlas Copco BBC 16W Pneumatic Rock Drill. Compare it to the reference callout on the diagram to be sure it is the position you need.
