A and B are next to joint collar on butt and shaft C and D are above and below wrap and a E ring is above butt cap FYI So yes it does have A and B
This has been debated before on here and different cuemakers call them differently. Southwest calls the A and B rings the rings above andYour C and D reference is actually A and B rings. I couldn't see a ring above the wrap. What happen to the 'A' ring?
