speaking of o rings. i oil mine before and after i use the marker. yet this last time when i took it apart afterwards one of the rings was really loose. I use C02 chich i understand can freeze o rings if you shoot too fast. i never shoot fast as i play sniper style woods and havent used it in speedball yet. anyways its on that vertical adapter behind the low pressere chamber, theres 2 inline orings, its the one towards the back of the marker. its an #015 80D o ring according to the diagram.
I'm confused cuz cold makes things contract, not expand. so why did the oring expand and get so loose it wouldnt stay on and had to replace it.
