Well I'm a newbie paintballer and I got my first gun a Spyder (unknown model) but discovered it was leaking CO2 out of the barrel. I took it to my local paintball shop and they fixed it up and it started working fine all that day. But later that night I wanted to show my dad the gun and screwed in the CO2 tank and it started leaking from the place under the grip handle on my gun. I looked under it and it seems there is a hole where a screw should be but I'm not really sure since I don't remember a screw being there. Help!
Here are some pictures of the area I think its leaking from if its not from under the grip handle its on the metal piece connecting the CO2 to it.
