Response to I built a .20 Disco Carbine

Does the OD of the barrel need to close to the ID of the barrel or is that what the O-ring is for? As far as picking a O-ring size what's the general guide lines on fit and tolerances? Really appreciate the help guys...I can tell this is going to be a fun project. Always have a blast makin chips.
