Thanks Rob, I've had a look. As I understand it, if you insert it fully, your eyepiece would still mount on the portion where the undercut occurs.
Also I don't have any of those eyepieces.
Replacement barrels are what is required. Perhaps I could fill the undercut grove with Spakfilla?
Actually, I'll try the suggestion of checking if there is a sharp inward facing edge on the brass compression ring and bevel it off. That sounds very promising.
