While moving back to my home country, I had emptied the air, and removed the screw next to the fill port, I was trying to remove the manometer, not sure what I was thinking, this was in November. My rifle was stuck in customs, and after a lot of back and forth, I finally was able to get it back. When I took the rifle out of the case, and was looking to put the screw back in, I felt something fall out. On searching the floor, I found a really tiny ball bearing, not sure if it fell from inside the area where the screw is supposed to go to. I have attached images. Can one of you please help me here. Also, the rifle was stored empty for close to 5 months. Will I have to replace any of the o-rings before trying to fill it up again. Thanks in advance.
