leaking problem on my sentinel
This is the first marker I have ever bought so I don't know a lot about them. I have a leak in it somewhere. My friend swears up and down that it is the VELOSITY PIN located on the inside of the piece on the front, under the barrel. This piece has the screw in it that regulates the co2 (i think?). I have gone to hardware stores trying to get the right size o-ring for it. Seems like a #6 or #7 could be the one. Does anyone know what size o-ring to get for this gun? It just says Sentinel on one side and AM on the other.
