Cheapest atf stop leak I've seen is £6 so I was thinking it's maybe worth a punt as a reseal is a faff and likely to cost more.
If it doesn't work then I can always use the fluid on the car!
Are the internal seals accessible/available - worth a thought before doing anything that is irreversible. Presumably you have tried different makes of CO bulbs, some are shorter/longer than others. Have you tried a Crosman bulb (contains lubricant for internal seals)?
