hi guys got my vamo v6 today it as an adjustable center pin that you turn with a flat screw driver , its fine with some big tanks but then with smaller 5.10 types it needs to be adjusted outwards then when i switch back to kanger i need to screw it back down , i was just wondering do i need to screw it back down or would tightening the kanger tank up tight push the pin back down ? as i ear some are adjustable floating pins would i do harm to it if i tightened the tank quite tight and if i unscrew all the way dose the screw come all the way out i dont want to mess to much with it as i dont no what im doing and i only had it today lol ,
